Poweredge 2900 PS1 predictive failure

Hi everyone,

I have a poweredge 2900 server (it is no longer under warranty). Yesterday I saw a warning icon in OpenManage for Power Supply 1: "presence detected. Predictive failure". So I shutted down the server and extracted the supplier. After 10 secs I pluged it back. Then the warning icon was gone.

This morning I checked again PS1 status on OpenManager, and the warning is back. I checked the log and every 2 minutes i get these messages: "A predictive failure detected on power supply 1" followed by "Power supply 1 is operating normally":

Screenshot below:

I really don't know how should I proceed... Should I wait till the PS 1 fails? If so, will PS2 keep the server "going on"?

Thanks, cheers,

Leticia
