Chapter 1
Overview
1.1 Introduction
Aside from 16 x 10/100Base-TX fast Ethernet port, the long MTBF (Mean Time
Between Failures) ensures that the EKI-7526I is a cost-effective solution and meets the
high reliability requirements demanded by industrial applications.
1.1.1 High-Speed Transmissions
The EKI-7526I 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 Input
EKI-7526I 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.
1.1.3 Flexible Mounting
EKI-7526I 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.
1.1.4 Advanced Protection
EKI-7526I supports up to 3,000 V
DC
EFT protection for power line, and also supports
4,000V
DC
ESD protection for Ethernet ports. With these 2 strong protections, it can
secure equipment against unregulated voltage and make systems safer and more
reliable. Further, EKI-7526I provides currency overload protection with a resettable
fuse to ensure that the device component won’t be damaged by overload current.
1.1.5 Wide Operating Temperature
The operating temperature of the EKI-7526I is between -40 ~ 75
℃
. With such a wide
range, you can use the EKI-7526I in some of the harshest industrial environments that
exist.
1.1.6 Easy Troubleshooting
LED indicators make troubleshooting quick and easy. Each 10/100 Base-TX port has 2
LEDs that display the link status, transmission speed and collision status. Also the
three power indicators P1, P2 and P-Fail help you diagnose immediately.
