EKI-2728I User Manual 2
1.1 Introduction
The EKI-2728I is a full industrial Gigabit Ethernet switch. Featuring 8 x 10/100/
1000Base-TX ports, EKI-2728I is designed not only to handle data intensive
applications, but also featuring the "Jumbo Frames" function with an MTU (Maximum
Transmission Unit) up to 9720 bytes in one frame, the switch can handle voice,
video, and even large multimedia transmissions at Gigabit high speeds.
1.1.1 High-Speed Transmissions
The EKI-2728I 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.
1.1.2 Dual Power Inputs
EKI-2728I redundant power input design is with power reverse protection to prevent
the switching device broken by wrong power wiring. When one of power inputs fails,
P-Fail LED will turn on and the relay output changes status for warning applications.
1.1.3 Flexible Mounting
EKI-2728I is extremely 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 environments.
1.1.4 Wide Operating Temperature
The operating temperature of the EKI-2728I is between -40 ~ 75° C. With such a
wide range, you can use it in some of the harshest industrial environments that exist.
1.1.5 Easy Troubleshooting
LED indicators make troubleshooting quick and easy. Each 10/100 Base-T port has 2
LED indicators that display the link status, transmission speed and collision status.
Also the system indicators P1, P2 and P-Fail help diagnose the switch immediately.
