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.
