Chapter 1
Overview
1.1 Introduction
The EKI-4524RI/4524ARI is a cost-effective solution, which meets the high reliability
requirements demanded by industrial applications. The equipment is able to operate in
wide temperature environments and supports variants of power input. Besides, the
EKI-4524RI/4524ARI is designed for the applications supposed to have certain electric
interference. Equipped with isolated power and isolated communication ports, the
device has high resistance toward electrical noise. It has been proved to work well for
harsh applications.
1.1.1 The SFP Advantage
The EKI-4524RI/4524ARI’s two SFP fiber slots provide a lot of flexibility for planning
and implementing a network. The slots can accept any SFP-type fiber transceivers
designed for transmitting over distances of either 500m (multi-mode), 10km, 30km,
50km, 70km or 110km (single-mode), and the slots support SFP transceivers for WDM
single-fiber transmissions. This means that you can easily change the transmission
mode and distance of the industrial switch by simply pulling out the SFP transceiver
and plugging in a different one. The SFP slots 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 transceiver in one slot and one 110km in the other.
1.1.2 High-Speed Transmissions
The EKI-4524RI/4524ARI 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.
1.1.3 19” Rack Mounting
The EKI-4524RI/4524ARI comes with a rack-mounted kit and can be mounted in an
EIA standard size, 19-inch Rack. The Switch can be placed in a wiring closet with other
equipment.
1.1.4 Advanced Protection
The power line of EKI-4524RI/4524ARI supports up to 4,000 V
DC
EFT protection, which
secures equipment against unregulated voltage and makes systems safer and more
reliable, while 8,000 V
DC
ESD protection for Ethernet ports makes the equipment more
suitable for harsh environments.
1.1.5 Easy Troubleshooting
LED indicators make troubleshooting quick and easy. Each 10/100 Base-TX port has
LED indicators that display the link status, transmission speed and collision status.
