Troubleshooting the Power Supply

Troubleshooting the Power Supply

To help isolate a power subsystem problem, follow these steps:

Step 1 Check whether the power supply LED labeled GOOD is on or the LED labeled FAIL is on. (on the DC multi-input power supply, the LEDs are labeled INPUT 1, 2, or 3 or OUTPUT FAIL.)

Step 2 If the LED labeled GOOD is off or if the LED labeled FAIL is on, take the following steps:

•Ensure that the power supply is flush with the back of the chassis.

•Unplug the power cord, loosen and reinstall the power supply, tighten the captive installation screws, and then plug in the power cord.

Step 3 If the LED labeled GOOD remains off, there might be a problem with the AC source or the power cable. Connect the power cord to another power source if one is available.

Step 4 If the LED labeled GOOD fails to light after you connect the power supply to a new power source, replace the power cord.

Note If this unit has more than one power cord, repeat Step 1 through Step 4 for each power input.

Step 5 If the LED labeled GOOD 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. Replace the power supply.

Step 6 If the LED labeled FAN OK fails to light when the switch is connected to a power source with a known good power cord, there is a malfunction in the fan that cools the power supply. Replace the power supply.

Step 7 If a second power supply is available, install it in the second power supply bay.

Step 8 Check that the LED labeled GOOD is on for the additional power supply. Check that the LED labeled FAIL is off.

Step 9 If the LEDs are not on, repeat the previous procedure to troubleshoot the second power supply.
