Chapter 1

1.1 Introduction

The 5 10/100TX w/ 4 PoE Injector Industrial Switch is a cost-effective solution and
meets the high reliability requirements demanded by industrial applications. Besides,
the equipment support 24V/48V DC power input and provides the PoE function w/
48V DC output for kinds of Powered Devices to receive power as well as data over the
RJ-45 cable.
1.1.1

High-Speed Transmissions

The EKI-2525PA 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-2525PA 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-2525PA is extremely compact (49 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-2525PA 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-2525PA 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-2525PA is between -40 ~ 75 ℃. With such a
wide range, you can use the EKI-2525PA 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.
