EKI-2725 User Manual 2

Chapter 1 Overview

1.1 Introduction

The EKI-2725 is a full industrial Gigabit Ethernet switch. Featuring 5 x

10/100/1000Base-TX ports, the EKI-2725 is designed not only to handle data intensive

applications, but by also featuring the "Jumbo Frames" function with an MTU

(Maximum Transmission Unit) up to 9Kbytes in one frame, the EKI-2725 can handle

voice, video, and even large multimedia transmissions at Gigabit high speeds.

1.1.1 High-Speed Transmissions

The EKI-2725 includes a switch controller that can automatically sense transmission

speeds (10/100/1000 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 Dual Power Input

EKI-2725 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.

1.1.3 Flexible Mounting

EKI-2725 is 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.

1.1.4 Advanced Protection

EKI-2725 supports up to 3,000 VDC surge protection for power line, and also supports

4000V 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-2725 provides currency overload protection with a resettable fuse to

ensure that the device component won’t be damaged by overload current.

1.1.5 Wide Operating Temperature

The operating temperature of the EKI-2725 is between -40 ~ 75 ℃ (wide operating

temperature model) or -10 ~ 60 ℃ (standard model). With such a wide range, you can

use the EKI-2725 in some of the harshest industrial environments that exist.

1.1.6 Easy Troubleshooting

LED indicators make troubleshooting quick and easy. Each 10/100/1000 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.
