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. 

 

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. 

 
 

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. 

 
 

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. 

 
 

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. 

 
 

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. 

 
 

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. 

 
 

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.
