Chapter 1
1.1 Introduction
Aside from 8 x 10/100Base-TX fast Ethernet ports, the EKI-7529MI, EKI-7529MI/ST
comes equipped with 2 x 100 Mbps fiber expansion ports. Also, the long MTBF (Mean
Time Between Failures) ensures that the EKI-7529MI, EKI-7529MI/ST is a cost-
effective solution and meets the high reliability requirements demanded by industrial
applications.
1.1.1

High-Speed Transmissions

The EKI-7529MI, EKI-7529MI/ST 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-7529MI, EKI-7529MI/ST 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-7529MI, EKI-7529MI/ST 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-7529MI, EKI-7529MI/ST supports up to 3,000 V
and also supports 4,000V
protections, it can secure equipment against unregulated voltage and make systems
safer and more reliable. Further, EKI-7529MI, EKI-7529MI/ST 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-7529MI, EKI-7529MI/ST is between -40 ~ 75 ℃.
With such a wide range, you can use the EKI-7529MI, EKI-7529MI/ST 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.
