Product Description - Magnum 6K25e Managed Fiber Switch
The Magnum Managed Fiber Switch boosts the performance of large Ethernet
LANs, typically serving as a “backbone” switch. It has the flexibility to handle a mix of
both fiber and twisted-pair switched ports along with Gigabit backbone port options.
Industry-standard IEEE 802.1p QOS prioritization is included, providing high
performance switching services for both “smooth” streaming and “bursty” data traffic.
The Magnum 6K25e has up to 25 ports capacity, all of which may be
configured as fiber ports, but still offers a space-saving rack-mount chassis that is only
1U (1.70in. or 4.32cm) high. The “mixed-media” capability allows user selection of all
popular flavors of fiber port connectors and modes, including even 10Mb fiber along
with Gigabit ports. It also allows a mix of 10/100Mb RJ-45 (copper) ports and a fiber

Gigabit port in the same unit. This flexibility is achieved via a family of 6K25e port
modules for copper and fiber-built-in (emphasizing Small Form Factor fiber for high
fiber port density), 6-port modules for fiber and RJ-45 combinations, and 1Gb port
module selections using GBICs. These modules can be factory configured in a base
chassis unit (or may be changed in the field by trained technicians) to adapt the unit to
the user’s application and Ethernet cabling requirements. Even evolving mixed-media
requirements for 10Mb and 100Mb fiber and copper as well as Gigabit ports can be
handled by the Magnum 6K25e product.
The 6K25e managed switches also provides PoE option via Power-pass-through and
power –inside PoE modules and allows the users to select a wide option of combo PoE
modules to support 802.3af pd devices. See details in sec 5.2.10 and 5.2.11. The Power
Sourcing Equipment (PSE), and are fully compatible with Powered Devices (PD)(e.g
wireless access points, IP phones) that comply with the IEEE 802.3af PoE standard. The
PoE switch ports have an auto-sensing algorithm, so that they provide power only to
802.3af, PoE end devices. PoE is managed by a multi-stage handshake to protect
equipment from damage and to manage power budgets .The PoE ports will
discontinue supplying power when the PoE powered devices are disconnected, and
support the 802.3af PoE PSE standard for over-current protection, under-current
detection, and fault protection.
The packaging and power-input options target the Magnum 6K25e at heavy-
duty applications. The chassis mounting rack style may be “regular” (with the ports and
LEDs in the front and the power input and management console connector in the rear) or
“Reverse” (with the ports and LEDs and the power-input and the management console
connector all in the rear and a duplicate set of LEDs in the front). Rack widths
accommodated include standard 19” RETMA, ETSI, and 23” Telco. Input power may be
AC, or –48VDC for Telco environments, or 24VDC for Industrial applications.
Designed for use in network traffic centers, the Magnum 6K25e Managed
Fiber Switches are easy to install and use. Addresses of attached nodes are automatically
learned, maintained and aged out, adapting the switching services to network changes.
LEDs provide status information on each port. The Magnum 6K25e provides high
performance plug-and-play hardware operation, 802.1p packet prioritization in hardware,
and industry-standard managed networks software functionality, all in convenient 1U
rack-mount packages.

Installation and User Guide (10/07)
2.2.1
Magnum 6K25e and 6K25eR chassis
The Magnum 6K25e is a 19” rack-mountable Ethernet Switch with three
eight-port slots (A, B, and C) and one Gb-only slot (D) for configuration flexibility. Slots
A, B and C may be configured with any of a large selection of fiber and copper port
types and combinations of types, typically eight ports per module, but sometimes 6 or 4
ports or even one Gb port. Slot D may be configured with a Gb module that accepts
GBICs. The port types configurable using the 4 slots allows the 6K25e to efficiently
serve a large variety of applications, especially using fiber media. The Magnum 6K25e
port modules are normally factory installed, but may be changed or added in the field.
(See Section 5)
Figure 2.2.1a: “Regular” 6K25e front view, configured for 24 +1 Gb ports
Status LEDs are part of each port module and are viewable when connecting
the Ethernet media. A “regular” rack-mount 6K25e is shown in Figure 2.2.1a. On
“Reverse” rack-mount models, there is a duplicate set of LEDs on the other (front) side
for normal status viewing from that direction. Of course, with management, the port
status data is also available in software.

2.2.9
Packet Prioritization, 802.1p QOS
Quality of Service means providing consistent predictable data delivery to
users from datagram paths that go all across a network. As a LAN device, the Magnum
6K25e can do its part to prevent any QOS degradation while it is handling Ethernet
traffic through its ports and buffers.
The Magnum 6K25e switching hardware supports the IEEE 802.1p standard
and fulfills its role in support of QOS, giving packet processing priority to priority tagged
packets according to the 802.1p standard. In addition to hardware support for QOS, the
MNS software (R2) supports two priority queues that can be shared across the eight
levels of defined packet priorities for application-specific priority control by the user
through software configuration settings.
2.2.10 Frame Buffering and Flow Control
Magnum 6K25e’s are store-and-forward switches. Each frame (or packet) is
loaded into the Switch’s memory and inspected before forwarding can occur. This
technique ensures that all forwarded frames are of a valid length and have the correct
CRC, i.e., are good packets. This eliminates the propagation of bad packets, enabling all
of the available bandwidth to be used for valid information.
While other switching technologies (such as "cut-through" or
"express") impose minimal frame latency, they will also permit bad frames to propagate
out to the Ethernet segments connected. The "cut-through" technique permits collision
fragment frames (which are a result of late collisions) to be forwarded which add to the
network traffic. Since there is no way to filter frames with a bad CRC (the entire frame
must be present in order for CRC to be calculated), the result of indiscriminate cut-
through forwarding is greater traffic congestion, especially at peak activity. Since
collisions and bad packets are more likely when traffic is heavy, the result of store-and-
forward operation is that more bandwidth is available for good packets when the traffic
load is greatest.
When the Magnum 6K25e Switch detects that its free buffer queue space is
low, the Switch sends industry standard (full-duplex only) PAUSE packets out to the
devices sending packets to cause “flow control”. This tells the sending devices to
temporarily stop sending traffic, which allows a traffic catch-up to occur without
dropping packets. Then, normal packet buffering and processing resumes. This flow-
control sequence occurs in a small fraction of a second and is transparent to an observer.
Another feature implemented in Magnum 6K25e Switches is a collision-based flow-
control mechanism (when operating at half-duplex only). When the Switch detects that

Installation and User Guide (10/07)
its free buffer queue space is low, the Switch prevents more frames from entering by
forcing a collision signal on all receiving half-duplex ports in order to stop incoming
traffic.
2.2.11 Managed Network Software (MNS-6K ) for Magnum 6K25e-Series
Magnum 6K25e’s come with Rel3.7 licensed MNS-6K software, which allows the user
to configure the Magnum 6K25e as a Managed Switch and implements security features

Installation and User Guide (10/07)
2.4
Applications
Magnum 6K25e Fiber Switches offer high performance and modularity. They
provide the flexibility of 100Mbps fiber and copper ports as well as Gigabit ports, with
industry-standard LAN management software. Magnum 6K25e Switches are easily used
in a variety of applications including MANs (metropolitan area networks) client/server
computing, secure VLAN- performance upgrades to departmental networks, and LAN
traffic centers require Gb backbone services. The performance characteristic of the
6K25e Switches enables them to inter-connect a series of subnets (one subnet per 6K25e
Switch port) in a LAN traffic center. The subnet connections may be via fiber or twisted
pair cabling, 100Mbps or 10 Mbps speed, and full-or half-duplex mode.
The mixed-media capability is ideal for upgrading existing Ethernet LAN
networks where existing cabling must be accommodated. The fiber-built-in media
capability is ideal for integrating future-proof fiber cabling into the LAN structure.
Example 1. In a Telecommunications storage data application, a secure managed switch
is required to provide an Ethernet backbone for a diversified network with multiple
subnets. The backbone consists of high speed LAN segments supported by 1000Mbps
full-duplex future-proof fiber media to provide secure long distance LAN connections.
The entire network is sharing a higher bandwidth Gigabit-enabled data-mining server for
the vital database located in a separate secured building. The copper ports are required
for multiple subnets inside the building. The entire spread network is managed to provide
easy, detectable, uninterrupted support through a viewable SNMP monitor.

Equipped with IGMP-L2 mode enhanced features allow the Magnum 6K25e to
meet the fastest growing application of video monitoring or video surveillance
demand of industry and provide an economical and effective solution to meet
that expectation.
3.0
Installation
Before installing the equipment, it is necessary to take the
following precautions:
1.) If the equipment is mounted in an enclosed or multiple rack
assembly, the environmental temperature around the equipment
must be less than or equal to 500C.
2.) If the equipment is mounted in an enclosed or multiple rack
assembly, adequate airflow must be maintained for proper and
safe operation.
3.) If the equipment is mounted in an enclosed or multiple rack
system, placement of the equipment must not overload or load
unevenly the rack system.
4.) If the equipment is mounted in an enclosed or multiple rack
assembly, verify the equipment’s power requirements to prevent
overloading of the building/s electrical circuits.
5.) If the equipment is mounted in an enclosed or multiple rack
assembly verify that the equipment has a reliable and
uncompromised earthing path.
6.) 24vdc, -48vdc, and 125vdc must be installed in restricted
access locations.
7.) CB-Circuit breakers of 10Amps should be shown on top of the
Rack.
This section describes installation of the
Magnum 6K25e Switches, as well as connection of
the various Ethernet media types.
3.1
Locating Magnum 6K25e Switches
The location of a Magnum 6K25e Switch
is dependent on the physical layout of the network.
Typically the Switch is placed in a central wiring
location where groups of network devices need to
be connected in order to communicate with each
other. These Switches are typically rack mounted in
a wiring closet see Section 3.3.2 below), but
because they have rubber feet they can also be installed on a shelf or table top unit. The
compact size allows it to be easily placed in an office or lab area, and it can also be either
shelf of wall-mounted (see Section 3.3.1 below). Figure 3.1: Location of the Magnum
6K25e’s cooling fans

Magnum 6K25e Gigabit Fiber Switch
Installation and User Guide (10/07)
Locate an AC receptacle that is within six feet (2 meters) of the intended
Magnum 6K25e site. The rugged metal case of the Magnum 6K25e will normally
protect it from accidental damage in a lab or workplace setting. Maintain an open view
of the front to visually monitor the status LEDs. Keep an open area around the unit so
that cooling can occur from the small fan on the left side, while the unit is in operation.
See figure below.
3.2
Connecting Ethernet Media
The Magnum 6K25e Switches are specifically designed to support all
standard Ethernet media types within a single Switch unit. This is
accomplished by using a family of different port Modules which can be
individually selected and configured per-port. See Section 2.4 for a description
of the PMs.
The various media types supported along with the corresponding IEEE
802.3 and 802.3u standards and connector types are as follows:

Connecting Fiber Optic ST-type, “twist-lock”
The following procedure applies to installations using a PM with ST-type fiber
connectors. This procedure applies to ports using a 6K25e module, MST-type
port.
1. Before connecting the fiber optic cable, remove the protective dust caps from the
tips of the connectors on the PM. Save these dust caps for future use.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue
dampened in alcohol. Make certain the connectors are clean before connecting.
Note:
One strand of the duplex fiber optic cable is coded using color
bands at regular intervals; you must use the color-coded strand on the
associated ports at each end of the fiber optic segment.

Installation and User Guide (10/07)
3. Connect the Transmit (TX) port (light colored post) on the Magnum PM to the
Receive (RX) port of the remote device. Begin with the color-coded strand of
the cable for this first TX-to-RX connection.
4. Connect the Receive (RX) port (dark colored post on the PM) to the Transmit
(TX) port of the remote device. Use the non-color coded fiber strand for this.
5.
The LINK LED on the front of the PM will illuminate when a proper
connection has been established at both ends (and when power is ON in
the unit). If LINK is not lit after cable connection, the normal cause is
improper cable polarity. Swap the fiber cables at the PM connector to
remedy this situation.
3.2.2
Connecting Fiber Optic SC-type, "Snap-In"
The following procedure applies to installations using a PM with SC-type fiber
connectors, i.e., using 6K-MSC, 6K-SSC single-mode.
When connecting fiber media to SC connectors, simply snap on the two square male
connectors into the SC female jacks of the 6KPM until it clicks and secures.
3.2.3
Connecting Single-Mode Fiber Optic
When using single-mode fiber cable, be sure to use single-mode fiber port
connectors. Single-mode fiber cable has a smaller diameter than multi-mode fiber cable
(9/125 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx
are the diameters of the core and the core plus the cladding respectively). Single-mode
fiber allows full bandwidth at longer distances, and may be used to connect 10 Mb nodes
up to 10 Km apart, or 18Km with the 6K-SSC.
The same procedures as for multi-mode fiber applies to single-mode fiber
connectors. Follow the steps listed in Section 3.2.2 above.
3.2.4
Connecting Twisted Pair (RJ-45,CAT3, CAT5, Unshielded or Shielded)
The RJ-45 ports of the Magnum 6K25e can be connected to the following two
media types: 100BASE-TX and 10BASE-T. CAT 5 cables should be used when making
100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3 may be
used. In either case, the maximum distance for unshielded twisted pair cabling is 100
meters (328 ft).
Media

NOTE : It is recommended that high quality CAT. 5 cables (which work for both 10 Mb
and 100Mb) be used whenever possible in order to provide flexibility in a
mixed-speed network, since dual-speed ports are auto-sensing for either 10 and
100Mb/s.

Installation and User Guide (10/07)
The following procedure describes how to connect a 10BASE-T or 100BASE-
TX twisted pair segment to the RJ-45 port. The procedure is the same for both
unshielded and shielded twisted pair cables.
1. Using standard twisted pair media, insert either end of the cable with an RJ-45
plug into the RJ-45 connector of the port. Note that, even though the connector is
shielded, either unshielded or shielded cables and wiring may be used.
2. Connect the other end of the cable to the corresponding device
3. Use the LINK LED to ensure proper connectivity by noting that the LED
will be illuminated when the unit is powered and proper connection is
established
NOTE: for Power Substations: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the RJ-45 ports are intended for
connectivity to other communication equipment such as routers or
telecommunication multiplexers installed in close proximity (i.e., less than 2
meters or 6.5ft) to the 6K25e. It is not recommended to use these ports in
substation applications to interface to field devices across distances which
could produce kigh (greater than 2500V ) levels of ground potential rise (GPR)
during line-to-ground fault conditions. The 6K25e passes the
1613specifications for zero packet loss with fiber ports & with RJ45 ports used
as indicated here.
3.2.5
Connecting Twisted Pair (CAT5E or better, Unshielded or Shielded)
The RJ-45 Gigabit ports of the Magnum 6K25e can be connected to the media
types, 1000BASE-T or CAT 5E or better 100-ohm UTP or shielded twisted pair (STP)
balanced cable. The CAT 5E or better 100-ohm UTP or shielded twisted pair (STP)
balanced cable is recommended to use when making 1000BASE-TX connections. In
either case, the maximum distance for unshielded twisted pair cabling is 100 meters (328
ft). See Section 4.3 for manual Up-Link switch on port 1 of copper port modules.

NOTE : It is recommended that high quality CAT. 5E cables (which work for both 100
Mb and 1000Mb) be used whenever possible in order to provide flexibility in a
mixed-speed network.
The following procedure describes how to connect a 1000BASE-T twisted pair segment
to the RJ-45 port. The procedure is the same for both unshielded and shielded twisted
pair cables.
1. 1000Base-T connections require that all four pairs or wires be connected. Insert
either end of the cable with an RJ-45 plug into the RJ-45 connector of the port.
Note that, even though the connector is shielded, either unshielded or shielded
cables and wiring may be used.

Gigabit SFP (Small Form-factor Pluggable) Optical Transceivers
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
communications for both telecommunication and data communications applications. Due
to its compact, hot pluggable characteristics, SFPs are becoming a very popular choice
for various applications. The small-chassis Magnum 6KQ is designed for industry-
standard Gb-SFPs and Gb-SFPCU (copper) for user selection of the SFP gigabit media
type as desired.
All SFPs used in Magnum 6KQs are compliant with the industry standard Multi-Source
Agreement (MSA) ensuring compatibility with a wide range of networking kit.

Note: It is highly recommended to remove the fiber cable first before
removing the SFP transceiver for any reason. Not removing the fiber cable first can
damage the fiber cable, cable connector or optical interfaces. It is advised not to remove
and insert a SFP transceiver frequently as this may shorten its useful life.
Note: Always use an ESD wrist strap while handling the SFP transceivers
since the SFP modules are static sensitive devices.
Note: The copper 1000BASE-T SFP transceiver port supports 1000Mb only. It is
recommended to use a straight-through RJ-45(4-twisted pair) connection while
connecting to any Server/workstation. While connecting with any Switch/repeater or
other device, it is recommended to use Crossover RJ-45 (4-twisted pair) category 5 or
higher cabling. The maximum length supported on copper 1000BASE-T is 100mts (328
ft.).

Magnum 6K25e Gigabit Fiber Switch
Installation and User Guide (10/07)
3.3.1
Rack-mounting (for 19” RETMA racks), regular Magnum 6K25es
Installation of a Magnum 6K25e Fiber Switch in a 19” rack is a simple
procedure. The units are 1U (1.70”) high. When properly installed, the front-mounted
LED status indicators should be in plain view and easy to read. Rack-mount installation
requires special 19” rack-mounted brackets and screws (included with each Magnum
6K25e unit). These brackets attach to the front sides of the Switch (regular package, i.e.,
not the Reverse version), which is then typically fastened into a standard 19” RETMA
rack as shown here.
The 23” brackets and the ETSI (European metric, approx. 21”) brackets are
also available (optional) for rack-mounting of Magnum 6K25e Switches. These brackets
are popular in the Telco industry where they are a standard for Central Office rack-
mounting purposes. The 23” and the ETSI brackets are mainly used for larger equipment

Ethernet cabling, there is no need to power down the unit. Individual segments can be
connected or disconnected without concern for AC power-related problems or damage to
the unit.
Power supply options are available to suit the 6K25e Switches to special high-
availability communications and/or heavy industrial-grade applications, including:
*
*
-48VDC, 24VDC and 125VDC with single DC input,
-48VDC, 24VDC and 125VDC with dual-source DC input,
See the Appendices of this manual for more details. Use an RFQ for other variations.
3.4.1 Alarm Contacts for monitoring internal power, and Software Traps
The Alarm Contacts feature, optional on Magnum 6K25e’s, provides two
Form C Normally Closed (NC) contacts to which the user can attach two sets of status
monitoring wires at the green terminal block. When this option is present, the terminal
block for Alarm Contacts is part of the Power Input panel in the Magnum 6K25e case.
The AC or DC power input connection is in the same panel. A manual On-Off Switch for
power to the unit is not available on 6K25e units with the Alarm Contacts option, as
these two features occupy the same space in the case.
The first NC Alarm Contact (top position) is a “Software Alarm”, operated
by user settings in the MNS-6K software. The user can disable the Software Alarm
feature with a software configuration command if desired. When the Software Alarm is
enabled, the Form C Normally Closed (NC) contact is held close during normal software
operation. A user-defined software malfunction, such as an SNMP Trap or a Software
Security violation or an S-Ring Fault, causes the contact to open and thus trigger an
alarm in the user’s monitoring system
The second (bottom position) NC Alarm Contact is held close when there is
power on the main board inside of the 6K25e. This provides a “Hardware Alarm”
because the NC contacts will open when internal power is lost, either from an external
power down condition or by the failure of the power supply inside of the Magnum 6K25e
Switch. Useful info. about Alarm contacts:
1. There is four terminal block (1,2,3,4)provided next to AC/DC power supply
2. The top two pins (1,2) are software operated
3. The bottom two pins (3,4) are hardware operated
4. By default it is NC (normally closed)
5. The software operation need to be enable and set to get the Alarm traps. For detail
information about the Software Alarm and software control of SNMP alarm traps, please
reference the Magnum MNS-6K Software User Manual. (Chapter 19th).

6K25e Port Module (6KPM) Installation
The Magnum 6K25e Switches are normally received from the factory with all
required 6KPM modules installed. There may be situations where 6KPM cards need to
be added or replaced. In cases where additional 6KPM cards are needed, the faceplate
for an available front-mounted slot must be removed. The following procedure describes
this operation.
3.5.1 Preparation for Installing and Removing 6KPMs
STOP!!!
Be sure the power cord and connections
for all powers single or dual, is unplugged
from the chassis before attempting to remove
and/or replace any PM cards.
Failure to do so may result in damage to the unit
and will void the warranty.
Caution- Avoid Static Discharge: The port modules (like most electronic
equipment) are sensitive to static discharge. Use proper ESD measures when
handling port modules.
Step 1. Make sure the 6KPM Card package has all necessary accessories to install it
properly. Each 6KPM Card package except the Gigabit, for field installation
contains (Daughterboard (Bigger) and Granddaughter board (smaller), three 5/8
stand offs for Granddaughter board, six #4-40 Pan-Head screws along with
Front panel face plate package. The Front panel faceplate package includes 3
retainer brackets and six #2-56 flat head screws.
NOTE: Every 6KPM Card package comes with their matching Daughter and
Granddaughter board. The copper 6KPM card should not work properly if
mixed with other Fiber combo 6KPM card packages. Always install the PM
module separately one by one to avoid the mixing.
Step 2. Remove Chassis Cover
The Magnum 6K25e chassis are combined with top and bottom parts and

assembled together with the help of 22 Philips-head screws. There are 7 screws located
on the front-bottom and rear-top of the unit and four screws each on the sides. Remove
these screws. Once these are removed, the top cover is easily lifted off the chassis base.
When the chassis top cover has been removed, the interior of the unit is exposed.
Figure 3.5.1a: Removing Chassis Cover
Caution: Be careful not to disturb the power supply.
Looking down into the Magnum 6K25e unit, notice that there are individual
PM installation spaces and female latch(white) connectors provided on the main board
along with four stand-off’s for each 6KPM card position. (See Figure 3.5.1b).
Figure 3.5.1b: Magnum 6K25e, Top view without chassis cover
Step 3. Remove front panel face plate retaining screws
There are four PM slots (A, B, C and D) located on the front of the chassis cover.
Looking into the vertical placed Chassis cover of the unit, there are three brackets with
retaining screws (#256 flat head ) which hold each PM Face plate card slot securely.
These six screws shown in the picture below are used to secure a PM face plate in
position, but unscrew only four of the screws as shown in Fig. below. These screws are
also used to secure the individual 6KPM cards screen plate which can be subjected to
significant forces from the attached cables. (See Figure 3.5.1c)

A Magnum 6K25e provides switched connectivity at Ethernet wire-speed
among all of its ports. The Magnum 6K25e supports10/100Mbs for copper media and 10
or 100Mb separate traffic domains for fiber ports to maximize bandwidth utilization and
network performance. All ports can communicate to all other ports in a Magnum 6K25e,
but local traffic on a port will not consume any of the bandwidth on any other port.

Magnum 6K25e Gigabit Fiber Switch
Installation and User Guide (10/07)
Magnum 6K25e units are plug-and-play devices. There is no software
configuring necessary to be done for basic operation at installation or for maintenance.
The only hardware configuration settings are user options for an UP-LINK Switch
(resides inside the unit) on the 6K8-RJ45. Optional Half / Full duplex mode and 10 or
100Mbps selection for the switched ports must be configured through MNS software per
unit as per the requirement. The internal functions of both are described below.
Filtering and Forwarding
Each time a packet arrives on one of the switched ports, the decision is taken to
either filter or to forward the packet. Packets whose source and destination addresses are
on the same port segment will be filtered, constraining them to that one port and relieving
the rest of the network from having to process them. A packet whose destination address
is on another port segment will be forwarded to the appropriate port, and will not be sent
to the other ports where it is not needed. Traffic needed for maintaining the operation of
the network (such as occasional multi-cast packets) are forwarded to all ports.
The Magnum 6K25e Switches operate in the store-and-forward switching
mode, which eliminates bad packets and enables peak performance to be achieved when
there is heavy traffic on the network.
Address Learning
All Magnum 6K25e units have address table capacities of 4K node addresses
suitable for use in larger networks. They are self-learning, so as nodes are added,
removed or moved from one segment to another, the 6K25e Switch automatically keeps
up with node locations.
An address-aging algorithm causes least-used addresses to fall out in favor of
frequently-used addresses. To reset the address buffer, cycle power down-and-up.

on the inside of the unit on the port module board next to the RJ45 port # 1 which it
controls. It enables the port’s cable to be cascaded (X) to a 10/100Mb repeater or
switching hub in the network. The manual Up-link switch position is configured as (=)
position as default factory setting, where used for all-copper module or combo modules.
4.4
Auto-Cross(MDIX) and Auto-negotiation, for RJ-45 ports
The RJ-45 ports independently support auto-cross (MDI or MDIX) in
auto-negotiation mode and will work properly with all the other connected devices
with RJ-45 port whether it supports Auto-negotiation or not (e.g 10Mb Hub, media
converter) or fixed mode at 10Mb or 100Mb Half/Full Duplex(managed switch). No
cross-over cable is required while using the 6K8’s copper port to other devices.
Operation is according to the IEEE 802.3u standard.
The Managed 6K25e-Series Fast Ethernet copper ports, can be set for either fixed 100Mb
speed or for 10/100 F/H N-way auto-negotiation per the IEEE802.3u standard. The
selection is made via MNS software. The factory default setting is for auto-negotiation.
At 10Mb or 100Mb-fixed speed, the user may select half- or full-duplex mode by MNS
Software for each RJ-45 port separately. For detail information See Section (10.1 at
page no.52) of this manual to access the “6K-MNS(Rel 3.7) Software user guide”
One frequently-used application for the Managed Magnum 6K25e Switch
copper ports is to connect one of them using a fiber media converter to another Switch in
the network backbone, or to some other remote 100Mb device. In this case, it is
desirable to operate the fiber link at 100Mb speed, and at either half- or full duplex mode
depending on the capabilities of the remote device. Standard commercially available
Fast Ethernet media converters mostly do not support auto-negotiation properly, and
require that the switched port to which they are connected be at 100Mb fixed speed.
Attachment to 10/100 auto-negotiation ports typically will not work properly. The
6K25e Switch’s RJ-45 ports handle this situation by configuring the ports as per desire
through MNS software port settings and can check the port status of each port after the
change.
When Magnum 6K25e RJ-45 copper ports are set for auto-negotiation and are
connected to another auto-negotiating device, there are 4 different speed and F/H modes
possible depending on what the other device supports. These are: (1) 100Mb full-duplex,
(2) 100Mb half-duplex, (3) 10 Mb full-duplex and (4) 10 Mb half-duplex.
The auto-negotiation logic will attempt to operate in descending order and will normally

Magnum 6K25e Gigabit Fiber Switch
Installation and User Guide (10/07)
arrive at the highest order mode that both devices can support at that time. (Since auto-
negotiation is potentially an externally controlled process, the original “highest order
mode” result can change at any time depending on network changes that may occur). If
the device at the other end is not an auto-negotiating device, the 6K25e’s RJ-45 ports
will try to detect its idle signal to determine 10 or 100 speed, and will default to half-
duplex at that speed per the IEEE standard.
General information -
Auto-negotiation per-port for 802.3u-compliant switches occurs when:
-- the devices at both ends of the cable are capable of operation at either 10
Mb or 100Mb speed and/or in full- or half-duplex mode, and can
send/receive auto-negotiation pulses, and . . .
-- the second of the two connected devices is powered up*, i.e., when
LINK is established for a port, or
-- the LINK is re-established on a port after being lost temporarily.
•
NOTE – Some NIC cards only auto-negotiate when the computer system
that they are in is powered up. These are exceptions to the “negotiate at
LINK – enabled” rule above, but may be occasionally encountered.
When operating in 100Mb half-duplex mode, cable distances and hop-counts
may be limited within that collision domain. The Path Delay Value (PDV) bit-times must
account for all devices and cable lengths within that domain. For Magnum 6K25e Fast
Ethernet switched ports operating at 100Mb half-duplex, the bit time delay is 50BT.
4.5
Flow-control, IEEE 802.3x standard
Magnum 6K25e Switches incorporate a flow-control mechanism for Full-
Duplex mode. The purpose of flow-control is to reduce the risk of data loss if a long
burst of activity causes the switch to save frames until its buffer memory is full. This is
most likely to occur when data is moving from a 100Mb port to a 10 Mb port and the
10Mb port is unable to keep up. It can also occur when multiple 100Mb ports are
attempting to transmit to one 100Mb port, and in other protracted heavy traffic situations.

Magnum 6K25e Gigabit Fiber Switch
Installation and User Guide (10/07)
Magnum 6K25e Switches implement the 802.3x flow control (non-blocking)
on Full-Duplex ports, which provides for a “PAUSE” packet to be transmitted to the
sender when the packet buffer is nearly filled and there is danger of lost packets. The
transmitting device is commanded to stop transmitting into the 6K25e Switch port for
sufficient time to let the Switch reduce the buffer space used. When the available free-
buffer queue increases, the Switch will send a “RESUME" packet to tell the transmitter
to start sending the packets. Of course, the transmitting device must also support the
802.3x flow control standard in order to communicate properly during normal operation.
Note: When in Half-Duplex mode, the 6K25e Switch implements a
back-pressure algorithm on 10/100 Mb ports for flow control. That is, the
switch prevents frames from entering the device by forcing a collision indication
on the half-duplex ports that are receiving. This temporary “collision” delay
allows the available buffer space to improve as the switch catches up with the
traffic flow.
4.6
Power Budget Calculations for Magnum 6K25e PM’s with Fiber Media
Receiver Sensitivity and Transmitter Power are the parameters necessary to
compute the power budget. To calculate the power budget of different fiber media
installations using Magnum products, the following equations should be used:
OPB (Optical Power Budget) = PT(min) - PR(min)
where PT = Transmitter Output Power, and PR = Receiver Sensitivity
Worst case OPB = OPB - 1dB(for LED aging) - 1dB(for insertion loss)
Worst case distance = {Worst case OPB, in dB} / [Cable Loss, in dB/Km]
where the “Cable Loss” for 62.5/125 and 50/125µm (M.m) is 2.8 dB/km,
and the “Cable Loss” for 100/140 (Multi-mode) is 3.3 dB/km,
and the “Cable Loss” for 9/125 (Single-mode) is 0.5 dB/km
and the “Cable Loss” for 9/125 (Single-mode) is 0.4 dB/km (LXSC25)
and the “Cable Loss” for 9/125 (Single-mode) is 0.25 dB/km
(LXSC40)
and the “Cable Loss” for 9/125 (Single-mode) is 0.2 dB/km (LXSC70)

* Note: The use of either multi-mode or single-mode fiber to operate at 100Mbps speed
over long distances (i.e., in excess of approx. 400 meters) can be achieved only
if the following factors are both applied:
•
The 100Mb fiber segment must operate in full-duplex (FDX) mode, i.e. the
full-duplex (factory default) setting for 100Mbps fiber ports must be used,
and
•
The worst-case OPB of the fiber link must be greater than the fiber cable’s
passive Attenuation.
(Attenuation = Cable loss + LED aging loss + Insertion loss + safety factor)

6KPM Module Description
An important feature of the Magnum 6K25e is the use of Port
Modules for flexible mixed-media connectivity to RJ-45 and fiber media. Since
the Magnum 6K25e Switches have dual-speed capability for copper ports, the 6
or 8-port interfaces are designed to support all standard Ethernet media types at
10 or 100Mps speed. Each 6K25e PM provides six or eight ports for
connecting Ethernet segments with its individual connector type and media.
For a list of 6K25e Port Module types, refer to Section 1.2
Each 6K25e PM is individually described in the following sections.
NOTE: The port #1 on the RJ-45 ports on all the modules, either all
RJ-45 ports or used for COMBO module is set as (=) other user ports.

feature eliminates the need for a special twisted pair crossover cable when connecting to
a hub or another switch.
Each port has an Activity (ACT) LED indicating packets being received, a
Link (LK) LED that indicates proper connectivity with the remote device when lit, a
FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when off), and a
“10/100” LED indicating 100Mb when lit (or 10 Mbps when off).
Important Note: The 10/100 RJ-45 ports are supported with Auto-negotiation and
Auto-crossover (MDIX), which allow the RJ-45 ports to automatically Link with any RJ-
45 device and eliminate the use of cross-over cable.
NOTE: for Power Substations: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the RJ-45 ports are intended for
connectivity to other communication equipment such as routers or
telecommunication multiplexers installed in close proximity (i.e., less than 2
meters or 6.5ft) to the 6K25e. It is not recommended to use these ports in
substation applications to interface to field devices across distances which
could produce kigh (greater than 2500V ) levels of ground potential rise (GPR)
during line-to-ground fault conditions. The 6K25e passes the
1613specifications for zero packet loss with fiber ports & with RJ45 ports used
as indicated here.

Installation and User Guide (10/07)
The LEDs on 6KP8-RJ45- PoE module are slightly different compared to
regular (non-PoE) RJ-45 modules as shown in Fig 2. When the PoE port is in use, the
PoE LED is ON when connected properly to a 803.af compliant PD device on that port.
When non-PoE devices are connected, the PoE LED is OFF. Operation of Ethernet data
traffic is not affected by PoE.
LINK and ACTIVITY LEDS are combined on the PoE modules into one LED
that is marked as LINK/ACT, as shown in the diagram.
PoE LEDs Summary
•
For PoE devices, each RJ-45 PoE port supports only 802.3af complaint
devices. The PoE LED is ON when the attached PD is drawing power from the
port.
•
•
For non-PoE devices connected, the PoE port will act as a normal RJ-45 port
and the PoE LED is OFF. No power is being sent out from the port.
The PoE ports in Magnum 6K’s with 48VDC power input act as a pass-
through, so the 48VDC power source must be strong enough to provide power
to the 6K switch and to all the 8 RJ-45 ports with PD devices connected (up to
15 watts per PoE port).
•
In the case where the 48VDC power in not internally connected and no power
is coming to the PoE ports for some reason, all the PoE port LEDs are ON
simultaneously to indicate a trouble condition. The ports will still operate
properly for data traffic.

It protects the Switch from incorrect DC input connections. An incorrect polarity
connection, for example, will neither affect the Switch, its internal power supply, nor will
it blow the fuse in the internal power supply.
The manual power “On-Off” Switch (optional) is used for powering the unit on
and off when it is placed into or taken out of service.

In this picture, the -48VDC
terminal block on the Magnum 6K25e
is located on the rear of the unit and is
equipped with three (3) screw-down
lead posts. It is similar for 24VDC and
125VDC options on Magnum 6K25e.
The leads are identified as negative (-),
ON
OFF
36-70VDC
positive (+),
48VDC and chassis ground (GND).
The actual connection procedure is very straightforward. Simply connect the
Figure B4.0: -48VDC Terminal Block on Magnum 6K25e-
leads to the Magnum unit, beginning with ground. Ensure that each lead is securely
tightened.
Note: The GND should be hooked up first. The 6K25e unit has a floating ground, so
the user may elect to Ground either + or = terminal to suit the customer’s use.
Before connecting hot lines to the Terminal Block of –48VDC, 24VDC or
125VDC, always use a digital voltmeter to measure the output voltage of the power
supply and determine the lead which is more “+ve potential”. The more “+ve” voltage
lead from 48V or –48V supply must be connected to the post labeled “+”.
An ON-OFF manual switch is optional for DC power. This can be used to cut
off power connections and as a RESET for the Magnum 6K25e Switch.

Magnum 6K25e Gigabit Fiber Switch
Installation and User Guide (10/07)
With the exception of the dual DC input power connections and the power
supply, all specifications and configuration options for the Magnum 6K25e -48VDC,
24VDC and 125VDC models with this Dual-Source option are identical to those listed in
the Magnum 6K25e Fiber Switches Installation and User Guide, including Appendix B
“Internal DC Power Supply Option”
C2.0
MAGNUM 6K25E, with -48VDC, 24VDC and 125VDC Dual-Source option
The 6K25e-Switch models with the internal -48VDC, 24VDC and 125VDC
Dual-Source power supply are designed for installations where a battery plant is the
power source, and where two separate power sources are utilized in order to increase
operational uptime and to simplify maintenance.
The functionality of the Magnum 6K25e Switch -48VDC, 24VDC and
125VDC Dual-Source Option units is identical to the standard AC-powered models.
Refer to the main sections of this Installation and User Guide for a detailed description
of the Magnum 6K25e Switches.

DUAL-SOURCE OPTION, THEORY OF OPERATION
The Dual-Source DC power

option is designed using diodes inside
of the chassis on each DC power input
line. A diode is placed in each of the
four input lines (behind the four

so that power from an external source

can only flow into the unit. This allows the unit to operate whenever DC power is
correctly applied to either or both of the two inputs
C4.0
FEATURES AND BENEFITS OF THE DUAL-SOURCE DESIGN
a) The Switch unit can receive power from either input, “A” or “B”. The hub will normally draw
its power from the DC source with the highest voltage at a given time.
b) The Switch unit will not allow power to flow from a higher voltage input to a lower voltage
input, i.e. the two DC power sources are not mixed together by the hub.
c) When one correct DC input is present, the Switch will receive power if the other DC input is
absent, or even if it is connected with reverse polarity or shorted or grounded.
d) Reverse polarity connections, if they should accidentally occur on either input, will not damage
the Switch or power supply internally (nor will it blow the fuse in the internal power supply)
because of the blocking action of the diodes. This is true even if one input connection is
reversed while the Switch is operating from the other source.
e) The Switch will not receive power (and will not work) when both inputs are simultaneously
absent or are both incorrectly connected.
