HP ML350 G5 Single processor server getting amber PPM2 LED on motherboard.

I am doing work for a school.   They have an ML350 G5 server purchased in 2008.  Single processor, 2 power supplies.  The server is on a UPS unit.

 

The PPM2 light on the mother board is on (amber).  This is confusing me because this is a single processor box.  Do I have to add a PPM in that slot even though it’s a single processor box?

 

I tried powering up with a single power supply (rather than 2).  Then tried the other one.  This had no effect. I don’t see any other issues with the box. I also blew all the dust out of the box.

 

Does anyone have any suggestions? I need to get this going ASAP.

Hi,

 

PPM 2 is not necessary if there is no second processor installed.

If PPM 2 led is amber/red then it indicates a issue with power supply or power backplane.

If you have another ML350 G5 server then swap the power supply from that server.

 

 

Thank You!
