Chapter 1 Overview
1.1 Introduction
To create reliability in your network, the EKI-2548I 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.
1.1.1 High-Speed Transmissions
The EKI-2548I 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 Dual Power Inputs
To reduce the risk of power failure, EKI-2548I provides +12 ~ 48 V
DC
or 24 V
AC
(18 ~
30 V
AC
) dual power inputs. If there is power failure, EKI-2548I will automatically switch
to the secondary power input.
1.1.3 Flexible Mounting
EKI-2548I is compact and can be mounted on a DIN-rail or panel, so it is suitable for
any space-constrained environment.
1.1.4 Wide Operating Temperature
The operating temperature of the EKI-2548I is between -40 ~ 75
o
C. With such a wide
range, you can use the EKI-2548I in some of the harshest industrial environments that
exist.
1.1.5 Easy Troubleshooting
LED indicators which make troubleshooting quick and easy help you diagnose the
system immediately.
