Installing and Connecting the Hardware
Verifying the Installation
To verify the hardware installation, observe the following indicators:
HThe PWR A and/or PWR B LEDs on the front panel must be in the ON state (green):
ÐIf you are using a single ±48 Vdc power source, then only the green DC PWR A LED will be ON.
ÐIf you are using dual Vdc power sources, then both the green
DC PWR A and DC PWR B LEDs will be ON.
ÐIf you are using a single ac power source, then the green PWR A LED must be ON.
ÐIf you are using both an ac power source and a ±48 Vdc power source, then both the PWR A and PWR B LEDs must be ON.
HThe yellow FAN ALM LED on the front panel must be OFF.
HAlso check the SYSTEM LEDs on the MCC and DSL cards if you have not done so already. The OK SYSTEM indicators on the cards must be in the ON state (winking green).
If these status indicators fail to appear as described, see Chapter 4, Troubleshooting, for troubleshooting procedures. Also refer to Appendix A, LEDs, for a complete list of these indicators and their descriptions.
