Hi, I am new to this managed networking switches... Pls. help me... I have Cisco Catalyst 3750G 24 port non poe with 4 SFP switch... It kept on working fine... One day on power outage it shuts down. As soon as the power resumed... It hanged itself with all LEDs kept lit... I waited for a while about 5 to 10 mins... When nothing happened I plugged it off from the electricity and then on... Again it hanged and kept hanging again and again for 4 to 6 times and then on 6th to 7th time it booted correctly with complete setting... I was shocked why this happened... Then till today at power outage it hangs with all light lit and after 4 to 5 times power off then on... Switch boots correctly... The switch has only Vlan 1... I am actually using it instead of un-managed switch... So it is simple switching... Pls. help... Thanks in Advance...

Sound like glitchy hardware. Probably hardware needs replacement.

Console output might provide more information when the system hangs during boot.

Laugh - reading the field notice that Leo provided - my prior post should be amended as:
