RJ-45 Connector
The RAU has one RJ-45 connector that connects it to an Expansion Hub using
Cat-5/5E/6 ScTP cable. Use shielded RJ-45 connectors on the Cat-5/5E/6 cable.
NOTE:
For system performance, use only Cat-5/5E/6 ScTP cable with
shielded RJ-45 connectors.

LED Indicators
Upon power up, the RAU goes through a two-second test to check the LED lamps.
During this time, the LEDs blink green/green red/red. This lets you visually verify
that the LED lamps and the firmware are functioning properly.
NOTE:
Refer to Section 9 for troubleshooting using the LEDs.
Status LEDs
The RAU status LEDs can be in one of the states shown in Table 5-2. These LEDs
can be:
