Chapter 1
Overview
1.1 Introduction
The EKI-2728 is a full industrial Gigabit Ethernet switch. Featuring 8 x
10/100/1000Base-TX ports, the EKI-2728 is designed not only to handle data intensive
applications, but by also featuring the "Jumbo Frames" function with an MTU
(Maximum Transmission Unit) up to 9Kbytes in one frame, the EKI-2728 can handle
voice, video, and even large multimedia transmissions at Gigabit high speeds.
1.1.1 High-Speed Transmissions
The EKI-2728 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-2728 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-2728 is compact (37 x 140 x 95 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-2728 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-2728 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-2728 is between -10 ~ 60
℃
. With such a wide
range, you can use the EKI-2728 in some of the harshest industrial environments that
exist.
1.1.6 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.
