Chapter 1
Overview
1.1 Introduction
To create reliability in your network, the EKI-7659CPI comes equipped with a
proprietary redundant network protocol—X-Ring that was developed by Advantech,
which provides users with an easy way to establish a redundant Ethernet network with
ultra high-speed recovery time less than 10 ms.
Aside from 8 x 10/100Base-TX fast Ethernet ports, the EKI-7659CPI comes equipped
with 2 combo 10/100/1000 Mbps RJ-45 copper ports or 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-7659CPI will
continue to operate until a Gigabit network infrastructure has been established, without
requiring any extra upgrade costs. Besides, the equipment support 48V DC power
input and provides the PoE function w/ 48V DC output for kinds of Powered Devices
to receive power as well as data over the RJ-45 cable.
1.1.1
The SFP Advantage
The EKI-7659CPI’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
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
High-Speed Transmissions
The EKI-7659CPI 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.
1.1.4
Dual Power Input
