EKI-7626C User Manual 2

Chapter 1 Overview

1.1 Introduction

Aside from 16 x 10/100Base-TX fast Ethernet ports, the EKI-7626C comes equipped

with 2 combo 10/100/1000 Mbps RJ-45 copper ports/mini-GBIC expansion ports.

Traditional RJ-45 ports can be used for uplinking wide-band paths in short distance (<

100 m), or the appropriate replaceable SFP module can be used for the application of

wideband uploading and long distance transmissions to fit the field request flexibility.

Also, the long MTBF (Mean Time Between Failures) ensures that the EKI-7626C will

continue to operate until a Gigabit network infrastructure has been established, without

requiring any extra upgrade costs.

1.1.1 The SFP Advantage

The EKI-7626C’s two SFP fiber slots provide a lot of flexibility when planning and

implementing a network. The slots can accept any SFP-type fiber module and these

modules are designed for transmitting over distances of either 500m (multi-mode),

10km, 30km, 50km, 70km or 110km (single-mode) – and the slots support SFP

modules for WDM single-fiber transmissions. This means that you can easily change

the transmission mode and distance of the switch by simply pulling out the SFP

module and plugging in a different module. The SFP modules are hot-swappable and

plug-and-play! Also, the fact that the switch has two of these slots, means that the

network manager can, for example, have one 10km module in one slot and one 110km

in the other.

1.1.2 High-Speed Transmissions

The EKI-7626C 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.

1.1.3 Dual Power Input

EKI-7626C 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-7626C is compact and can be mounted on a DIN-rail or panel, so it is suitable for

any space-constrained environment.

1.1.5 Advanced Protection

The power line of EKI-7626C supports up to 3,000 V

EFT protection, which secure

equipment against unregulated voltage and make systems safer and more reliable.

Meanwhile, 4,000 V

ESD protections for Ethernet ports make EKI-7626C more

suitable for harsh environments.
