Hi guys,
I recently bought a bunch of cisco 3750-x switches. I configured them all and started deploying them. A day later, some of the switches started failing on me. When I connect the power cord to the AC main, the power supply module on the back shows "AC OK" LED Green but the "PS OK" LED shows Red. I started referring to the installation guide and it told me that "PS OK" LED turns RED when output has failed. Guessing this I checked with another power supply module that was working, but still I get the same LED indicators.
The original power supply module works with other switches. What could be the problem? IOS crash...?
