Chapter 1
1.1 Introduction
Aside from 16 x 10/100Base-TX fast Ethernet ports, the EKI-7526MI comes equipped
with 2 100 Mbps fiber expansion ports. Also, the long MTBF (Mean Time Between
Failures) ensures that the EKI-7526MI is a cost-effective solution and meets the high
reliability requirements demanded by industrial applications.
1.1.1

High-Speed Transmissions

The EKI-7526MI 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-7526MI 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-7526MI 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-7526MI supports up to 3,000 V
4,000V ESD protection for Ethernet ports. With these 2 strong protections, it can
DC
secure equipment against unregulated voltage and make systems safer and more
reliable. Further, EKI-7526MI 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-7526MI is between -40 ~ 75 ℃. With such a
wide range, you can use the EKI-7526MI 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.
