Cisco 4900 switch Power supply frequent failure

Hi,


I am facing this problem with one of our customer data center where so far total 8 power supplies were replaced due to the failure of the power supply.

#show power  - shows the power BAD and both input/output power LED in rear side of the chassis shows RED in clour. I advised the customer to check /test their data center power problems and the PDUs that feeds the power to the switches. Is there any thing left in switch part to check and analyse.

Field notice shows nothing related to this issue.

Thx

Aru,

I would suggest the same which you have said.


Kindly ask your customer to check the power source which is providing power to this device?


Second how many devices are facing this issue at the site?


Could you ask them to change the power source for this device to be the stable one which has ups connection.


There is nothing related for this under the field notice:
