Power Supply Not Recognized

[ggoodspeed]

Someone put a Catalyst 6500 on my desk and said, "Fix it." It has a supervisor engine running CatOS 6.3. It has two power supplies, but any card inserted into the chassis will not power up. How do I fix this? "Show environment power" gives this result:

First check if the power supply model is supported by the chassis. Here is the compatibility matrix.

If the power supply is supported use this procedure to check the power supply unit.

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 good and the power supply is functional.

- If the INPUT OK LED is off, first ensure that the power supply is flush with the back of the chassis. Turn off the power switch, tighten the captive installation screw(s), and then turn on the power switch.

- If the INPUT OK LED remains off, there might be a problem with the AC source, the DC source, or the power cable.

- Turn off the power to the switch, connect the power cord to another power source if one is available, and turn on the power.

- If the INPUT OK LED is green, the problem is the first power source.

- 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 on the switch.

- If the INPUT OK LED then goes on, return the first power cord for replacement.

- If this unit has more than one power cord, repeat the procedure again for each power supply.

- 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.
