How to Confirm Whether 6300 Power Supply Module is Bad

Hello AcmeHeads

Just received a call that a 6300 SBC is no longer receiving traffic. Moved ASAP to the Switch Room and discovered that the SBCs are not Powered. We started investigations as follows:

1. Located Power Source noted that it was supplying power. The lights indicated this.

2. Unplugged the 2 Power Cables that goes into the SBC. Didn't have a Voltmeter availble, so we Plugged the Cable into a Monitor. Both Cables powered the Monitor.

 

Suspecting that the Power Module is BAD. But both of them?

3. I pulled out a Module and put close to my nose. Doesn't smell like anything got burnt.
