Front Panel
The front panel of the Model EN308
TC
hub contains LEDs that monitor the
activity status of the hub.
For ease of use, the front panel 10BASE-T LEDs that indicate link, receive, or
partition activity are duplicated on the 10BASE-T ports on the rear panel. Use
the rear panel LEDs when setting up the device, and use the same LEDs on the
front panel for monitoring the ports when the hub is positioned in place and set
up.
