Chapter 4 Troubleshooting Hardware Troubleshooting Power Supply Issues Send documentation comments to [email protected] Troubleshooting the Power Supplies To isolate a power supply problem, follow these steps: Step 1 Step 2 Verify that the Input Ok LED on the power supply is green. If the Input Ok LED is green, the AC or DC source is operational and the power supply is functional. If the Input Ok LED is off, first ensure that the power supply is flush with the chassis. Turn the power switch off, tighten the captive screw(s), and then turn the power switch on (|). If the Input Ok LED remains off, there might be a problem with the AC source or the DC source, or with the power cable. a. Turn off the power to the switch by pressing or turning both power switches to 0, connect the power cord to another power source if one is available, and turn the power on. If the Input Ok LED is now green, the problem was the first power source. b. If the Input Ok LED fails to light after you connect the power supply to a new power source, replace the power cord and turn the switch on. If the Input Ok LED lights at this point, return the first power cord for replacement. c. If the Input Ok LED still fails to light when the switch is connected to a different power source with a new power cord, the power supply is probably faulty. If a second power supply is available, install it in the second power supply bay and contact your customer service representative for further instructions.

Choose Physical > Power Supplies on Device Manager or use the show environment power command to verify the status of your power supplies. (See Example 4-1.)
