Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from damage.
1. To avoid electrical shock, always disconnect the power from your PC chassis before you
work on it. Don't touch any components on the CPU card or other cards while the PC is
on.
2. Disconnect power before making any configuration changes. The sudden rush of power
as you connect a jumper or install a card may damage sensitive electronic components.

Chapter 1 Overview
1.1 Introduction
The EKI-2525P is a cost-effective solution and meets the high reliability requirements
demanded by industrial applications. Using fiber port can extend the connection
distance that increases the network elasticity and performance. Besides, the industrial
switch provides the PoE function for kinds of Powered Devices to receive power as
well as data over the RJ-45.
1.1.1
High-Speed Transmissions
The EKI-2525P includes a switch controller that can automatically sense transmission
speeds (10/100 Mbps). The RJ-45 interface can also be auto-detected, so MDI or MDI-
X is automatically selected and a crossover cable is not required. All Ethernet ports
have memory buffers that support the store-and-forward mechanism. This assures that
data is properly transmitted.
1.1.2
Power-over-Ethernet (PoE)
PoE eliminates the need to run AC power to other devices on a wired LAN. While using
Power-over-Ethernet system, installers need to run only a single Category 5 Ethernet
cable that carries both power and data to each device. This allows greater flexibility in
the locating of network devices and significantly decreasing installation costs in many
cases.
1.1.3
Dual Power Input
EKI-2525P redundant power input design is with power reserve protection to prevent
the switch device broken by wrong power wiring. When one of power input is fail, P-
Fail LED will turn on and send an alarm through a relay output for notifying user.
1.1.4
Flexible Mounting
EKI-2525P is extremely compact (37 x 140 x 95 mm) and can be mounted on a DIN-
rail or a panel, so it is suitable for any space-constrained environment.
1.1.5
Advanced Protection
EKI-2525P supports up to 3,000 VDC surge protection for power line, and also
supports 4,000V ESD for Ethernet ports. With these 2 strong protections, it can secure
equipment against unregulated voltage and make systems safer and more reliable.
Further, EKI-2525P provides currency overload protection with a resettable fuse to
ensure that the device component won’t be damaged by overload current.
1.1.6
Wide Operating Temperature
The operating temperature of the EKI-2525P is between -10 ~ 60 ℃. With such a wide
range, you can use the EKI-2525P in some of the harshest industrial environments that
exist.
1.1.7
Easy Troubleshooting
LED indicators make troubleshooting quick and easy. Each 10/100 Base-TX port has 2
LEDs that display the link status, transmission speed and collision status. Also the
three power indicators P1, P2 and P-Fail help you diagnose immediately.

2.3 Mounting
The EKI-2525P supports two mounting methods: DIN-rail & Wall.
2.3.1
Wall mounting
EKI-2525P can be wall-mounted by using the included mounting kit. Then, hang on the
EKI-2525P to the nails on the wall.
First, use the screws included in the package to combine the EKI-2525P and metal
mounting kit. And then you can install the device firmly via the components, please see
Figure 2.5 as below.

2.3.2
DIN-rail Mounting
You can also mount EKI-2525P on a standard DIN-rail by below steps.
The DIN-rail kit is screwed on the industrial switch when out of factory. If the DIN-rail kit
is not screwed on the industrial switch, please screw the DIN-rail kit on the switch first.
First, hang the EKI-2525P to the DIN-rail with angle of inclination. See figure 2.6.

2.4 Network Connection
The EKI-2525P has 5 x RJ-45 ports that support connection to 10 Mbps Ethernet, or
100 Mbps Fast Ethernet, and half or full duplex operation. EKI-2525P can be
connected to other hubs or switches through a twisted-pair straight through the cable
or a crossover cable up to 100m long. The connection can be made from any TX port
of the EKI-2525P (MDI-X) to another hub or switch either MDI-X or uplink MDI port.
The EKI-2525P supports auto-crossover to make networking more easy and flexible.
You can connect any RJ-45 (MDI-X) station port on the switch to any device such as a
switch, bridge or router.
2.5 Power Connection
The EKI-2525P supports dual 48 VDC power inputs and power-fail relay output.
Figure 2.8: Pin Assignment of the Power Connector
You can connect an alarm indicator, buzzer or other signaling equipment through the
relay output. The relay opens if power input 1 or 2 fails (‘Open’ means if you connect
relay output with an LED, the light would be off).

Chapter 3 Troubleshooting
1.
Power Input
Verify that is using the right power cord/adapter 48 VDC, please don’t use the power
adaptor with DC output voltage higher than 48V, or it will burn this converter down.
2.
Cable
Select the proper UTP cable to construct user network. Please check that is using the
right cable. Use Unshielded Twisted-Pair (UTP) or Shielded Twisted-Pair (STP) cable
for RJ-45 connections: 100 Category 3, 4 or 5 cable for 10 Mbps connections or 100
Category 5 cable for 100 Mbps connections. Also, be sure that the length of any
twisted-pair connection does not exceed 100 meters (328 feet).
3.
Diagnosing LED Indicators
The switch can be easily monitored through panel indicators, which describes common
problems user may encounter and where user can find possible solutions, to assist in
identifying.
If the power indicator does not light up when the power cord is plugged in, user may
have a problem with power cord. Then check for loose power connections, power
losses or surges at power outlet. If user still cannot resolve the problem, contact the
local dealer for assistance.
If the Industrial switch LED indicators are normal and the connected cables are correct
but the packets still cannot transmit, please check your system’s Ethernet devices
configuration or status.
