- Depends some switches may have snmp-bugs when reporting power supply statuses (also depends on the software version they are running). Better then is to log in to the device; look at the logs. And or issue commands such as show env all If that is not conclusive you may need to go and look at the device and or the leds on the power supplies.

-- Each morning when I wake up and look into the mirror I always say ' Why am I so brilliant ? '
When the mirror will then always repond to me with ' The only thing that exceeds your brilliance is your beauty! '
