Chapter 1
Overview
1.1 Introduction
The EKI-2728MI is a full industrial Gigabit Ethernet switch. Featuring 6G + 2G Fiber
ports, the EKI-2728MI is designed not only to handle data intensive applications, the
EKI-2728MI can handle voice, video, and even large multimedia transmissions at
Gigabit high speeds.
1.1.1 High-Speed Transmissions
The EKI-2728MI includes a switch controller that can automatically sense transmission
speeds (10/100/1000 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-2728MI 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-2728MI is compact (59.6 x 105 x 152 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-2728MI supports up to 3,000 VDC surge protection for power line, and also
supports 4,000V ESD for Ethernet ports. With these 2 strong protections, it can secure
equipment against unregulated voltage and make systems safer and more reliable.
Further, EKI-2728MI provides currency overload protection with a resettable fuse to
ensure that the device component won’t be damaged by overload current.
1.1.5 Green Power
The EKI-2728MI has a special function. The switch will automatically detect Ethernet
ports status and Cable Length and adjust power efficiency. It saves 5.49% power
consumption for cable length 20m.
1.1.6 Industrial Operating Temperature
The operating temperature of the EKI-2728MI is between -40 ~ 75
℃
. With such a
application range, you can use the EKI-2728MI in some of the harshest industrial
environments that exist.
1.1.7 Easy Troubleshooting
LED indicators make troubleshooting quick and easy. Each 10/100/1000Base-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 the status immediately.
