Chapter 1 Overview

1.1 Introduction

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

To reduce the risk of power failure, the EKI-7626C/7626CI provides +12 ~ 48 V

dual

power inputs. When one of the power inputs fails, P-Fail LED will turn on and send an

alarm through a relay output for notifying the user; and the switch will toggle to the

secondary power input.

1.1.4 Flexible Mounting

EKI-7626C/7626CI 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/7626CI 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/7626CI more suitable for harsh environments.
