INITIAL START-UP TEST AND

STAND ALONE OPERATION

Following insertion into the mounting shelf, the STATUS LED will initially turn red to indicate the start of self-test diagnostics. While self-test diagnostics are in progress, all LEDs will turn yellow and then remain on until self-test diagnostics are completed.

Following the successful completion of self-test diagnostics, the front panel LEDs will appear as follows:

STATUS - Green to indicate that self-test diagnostics were successfully completed.

LPBK - Off

NET/LOS - Red to indicate that the network DS1 signal is not being received by the RLX.

LINE/LOS - Red to indicate that the line DS1 signal is not being received by the RLX.
