HUB(8)-U( ) ETU

8.7.1

Description

The HUB(8)-U( ) ETU is an optional Ethernet interface for the Electra
Elite IPK II KSU that supports eight Ethernet ports. Each port has
two LEDs that indicate status and activity.
A HUB is a switching point for data that comes together from
individual ports. A switch determines the port where the data should
be forwarded and regulates transmission. The HUB(8)-U( ) ETU
provides an efficient platform when multiple ETUs that require
Ethernet connection are installed in the Electra Elite IPK II KSU.
One port can be a source port, and another port can be set as a
target port to mirror the source and monitor data traffic.
