Chapter 3
Operation
The 9M426-02 FDDI SmartSwitch Module is a three port switch module with two
front panel HSIM interfaces and one INB-2 backplane interface. This module,
with the proper HSIM, may be used for an FDDI, ATM, WAN and other
high-speed connectivity for the SmartSwitch 9000 chassis.
System Management Buses
There are two management channels within the SmartSwitch 9000 system: the
SMB-1 and the SMB-10. These buses provide out-of-band management and inter-
module management communication.
SMB-1 Bus
The SMB-1 is a 1Mbs management bus located within the SmartSwitch 9000. This
bus is utilized by all diagnostic controllers in the system including connectivity
modules, power supply modules and the environmental module. The SMB-1
transports inter-chassis information between system components, such as power
and environmental information, as well as diagnostic messages. Periodic
loop-back tests are performed by all modules which share this bus to ensure the
validity of SMB-1. In the event a failure is detected on SMB-1, the SMB-10 may be
used as an alternate communication channel.
SMB-10 Bus
The SMB-10 is a 10Mbs management bus located within the SmartSwitch 9000
which is also used for inter-chassis communication of modules as well as serving
as an out-of-band management channel into the SmartSwitch 9000. The SMB-10 is
externalized from the chassis via an optional Ethernet Port Interface Module
(EPIM) located on the front of the Environmental Module. Through an EPIM
connection, full SNMP management of the SmartSwitch 9000 is available out-of-

Operation
band from user data. Modules which share the SMB-10 bus periodically send out
loop-back packets to ensure the validity of SMB-10. In the event a fault is detected
on the SMB-10, the SMB-1 can be used as an alternate communication channel by
the modules.
System Diagnostic Controller
This diagnostic controller is composed of a Z-80 microprocessor and its
supporting logic. The diagnostic controller is designed to control the power-up
sequencing of modules, monitor the 9M426-02 input and output power
parameters, keep watch over the main host processor, as well as monitor the
temperature and control the SMB LANVIEW diagnostic LED. Although the
diagnostic controller and the main host processor can operate independent of
each other if needed, they exchange information about each other’s status and
overall module condition. The information gathered by the diagnostic controller
is available to the network manager via local/ remote management and the LCD
located on the environment module. The 9M426-02 has been designed so that in
the event of a diagnostic controller fault, the 9M426-02 will continue to function.
DC/DC Converter
The DC/ DC converter converts the 48 VDC on the system power bus to the
necessary operating voltages for its host network services module. The diagnostic
controller monitors and controls the operation of the DC/ DC converter.
INB Interface
Each module that attaches to the INB has an INB Network Interface Block (NIB).
The INB NIB converts canonical frames to fixed length data blocks for
transmission onto the INB. For data blocks received from the INB, the INB NIB
reassembles the data blocks received from the INB back into canonical frames for
transmission to the SmartSwitch ASIC then from the SmartSwitch ASIC to the
front panel ports.
SecureFast Switch
The SmartSwitch ASIC is a hardware based switch design that is the key building
block of the SmartSwitch 9000. All filtering/ forwarding decisions are made in
hardware as opposed to software as in traditional switches. This custom
hardware allows the SmartSwitch ASIC to process over 150K frames per second.
The SmartSwitch ASIC is designed to support up to 64 ports that are shared
3-2

Operation
between the host processor, the INB backplane, and LAN/ WAN interfaces on the
front panel of SmartSwitch 9000 modules. The SmartSwitch ASIC can operate in
two modes: as a traditional switch, or as a SecureFast Switch (SFS). When
operating in traditional switch mode, it makes filtering/ forwarding decisions
based on Destination Address (DA), with standard IEEE 802.1d learning. When
operating in SecureFast Switch mode, all filtering/ forwarding decisions are made
based on a DA-SA pair and its receive port. These DA-SA pairs with the
associated receive port are programmed into the switch using Cabletron’s
SecureFast Virtual Network Server (SecureFast VNS). This provides the network
administrator with the ultimate network security without the performance
degradation found when using routers or traditional switches with special
filtering capabilities. The SmartSwitch 9000 enterprise switching system can
support modules operating in traditional switch mode and SecureFast Switch
mode simultaneously providing security when/ where needed and ease of
configuration where security is not required.
i960 Core
The i960 core provides the SNMP protocol stacks, to support industry standard
MIBs. Additionally, Cabletron enterprise extension MIBs are supported for each
media type. Advanced management services, such as the Distributed LAN
Monitor, telnet and network address to MAC address mapping, are also provided
by the i960 core.
The Host engine sends and receives packets via the CPU SmartSwitch ASIC
Interface. This allows the traditional switch to perform spanning tree protocol and
other traditional switching functions. The SMB Interfaces provide communication
to the Host Engine for management functions and communication with other
modules in the chassis.
