Changes

If Power Circuit or Power Cord is interrupted from the source to the server, System Admins may generate Service Requests for investigation.

Cause

Input power problems are typically related to an interruption of a server's input power possibly due to a popped breaker or loose power cord.

Solution

Verify that the PSU's breaker was not turned off and that the power cord was securely connected during the time of the problem. If the problem reoccurs after these items are checked, then PSU failure would be the most likely cause.
