Troubleshooting the Power Subsystem

Check the following to help isolate a problem with the power system.

•Does the POWER LED come on when system power is turned on? If not:

–AC—check to ensure that the AC power cord is plugged in to the power supply and the power source (wall or power strip).

–DC—verify that the –48 and +48-V leads are correctly attached to the power supply.

–Verify that the system is properly grounded.

–Ensure that the voltage selection switch is in the appropriate AC or DC position.

•If you are unable to resolve the problem, see the “Obtaining Technical Assistance” section on page 12 for information on contacting Cisco technical assistance.
