High-Speed Transmissions; The Sfp Advantage; Dual Power Input; Flexible Mounting - Advantech EKI-7629C User Manual

Chapter 1
1.1 Introduction
Aside from 8 x 10/100Base-TX fast Ethernet ports, the EKI-7629C/CI 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 up-linking 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 flexibly.
Also, the long MTBF (Mean Time Between Failures) ensures that the EKI-7629C/CI will
continue to operate until a Gigabit network infrastructure has been established, without
requiring any extra upgrade costs.
1.1.1

High-Speed Transmissions

The EKI-7629C/CI 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.
1.1.2

The SFP Advantage

The EKI-7629C/CI'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 dis- tances 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 mod- ule in one slot and one 110km
module in the other.
1.1.3

Dual Power Input

EKI-7629C/CI 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-7629C/CI is extremely compact (79 x 152 x 105 mm) and can be mounted on a
DIN-rail or a panel, so it is suitable for any space-constrained environment.
1.1.5

Advanced Protection

EKI-7629C/CI supports up to 3,000 V
supports 4,000V
it can secure equipment against unregulated voltage and make systems safer and
more reliable. Further, EKI-7629C/CI provides currency overload protection with a
resettable fuse to ensure that the device component won't be damaged by overload
current.
