Cisco Switch - Power Supply self-protection?

Unanswered Question

Do the power supplies in Cisco switches have any built-in self protection?  I've been unable to find any references on the web.


The reason that I ask the question is that we have had several cases of switches losing power - sometimes but not always after a known power cut - but pulling and re-inserting the power cord brings the switch back to life so something appears to have caused the power supply to stop supplying power to the system.


I have seen this now on 3750G, 2960S and 3550.


If there are any protection policies then this may indicate problems with the power supply on this particular site; we have not noted it anywhere else.


The cabinets do not have UPS protection (that is a separate discussion...).


Thanks in advance for any help.

Robin,

There is nothing as such present. I request you to kindly arrange for the UPS.
