Removing and Replacing the LED Board
Installation Checkout
Perform the following steps to verify that the new LED board functions correctly.
Note The following warning is for units with
Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. (For translation of this safety warning, refer to the section “DC Power Connection Warning” on page 18.)
Step 1 Turn all power supplies back ON and observe the three system status indicators on the front panel.
Step 2 When you turn each power supply ON, the corresponding upper power and lower power LEDs on the front panel should go on for each bay in which a power supply is installed and turned ON. If any do not go on, do the following:
•Check the AC power LED on the power supply. If it is on, suspect that the front panel LED has failed and proceed with the installation checkout to determine if the other LEDs go on.
•If the AC power LED is not on, or if the DC fail LED is on, ensure that the power supply is fully inserted in the power supply bay and that the captive installation screw on the top of the supply is tightened. The switch will not turn completely to the ON () position unless the supply is installed correctly.
•Ensure that the power cord is fully seated in the power supply port and that the retention clip is snapped up around the plug.
•Check the cable connection at the power source and ensure that it is connected properly.
•If the AC Power on the power supply still fails to go on, suspect a power supply failure. If a second (redundant) power supply is available and functioning properly, proceed with the installation checkout.
Step 3 After the system boots successfully, verify that the front panel normal LED goes on. If it does not go on, do the following:
•Check the normal LED on the RP (in the Cisco 7000) or the RSP2 (in the Cisco 7507). If it is on, the system software is functioning properly. Turn all power supplies OFF and reseat the LED board by following steps 2 through 6 in the section “Installing a New LED Board” on page 13.
•If the (RP or RSP2) normal LED fails to go on, the system software has failed to boot properly. Toggle the power supplies OFF then ON again and observe the behavior of the LEDs on the RP or RSP2, so that you can report it to a service representative if you need to call for technical assistance.
This completes the installation checkout.
