Troubleshooting the Installation
• If the Fault indicator is on, the power supply is faulty. Replace the power supply.
• If the Temp and Fault indicators are on, an over-temperature condition exists:
◦ Verify that the power supply fan is operating properly.
◦ If the fan is not operating, replace the power supply.
◦ Contact your Cisco representative if replacing the power supply does not fix the problem.
