2920 Won't boot

[cloidhamer]

We had a power outage and our backup generator didn't kick on last night. When I came in to work one of my 2920 switches was not working. When powered on the blue location light comes on and the fans spin up. Then the location light goes off and the fans spin down. It repeats this on/off cycle endlessly. I tried accessing the console, but nothing gets posted just a black screen. I tried many searches and couldn't find anything. Any help would be appreciated.

Hello,

What is the switch LED status while booting?

Hope you have config backup, if yes then Please restore to factory default configuration.

1.  Press clear and reset button simulatenously.

2. While continuing to press Clear, release Reset.

3. When the Test LED begins blinking (after aprrox 25secs), release Clear.

The switch removes all configuration changes, restores the factory default configuration, and runs self test.

If it wont came up after factory reset then you might need to replace the switch.

Thanks!

Only the blue Location LED lights up. Pressing the Clear and Reset buttons does nothing. Could this be a symptom of a bad power supply?
