PE 2800 - Removed redundant power supply - can't get rid of alerts

I have a PE 2800 that only runs on a single power supply.  I needed to do some online maintenance and needed to keep the server power while I swapped out the single power supply.

To accomplish this I put a second power suuply in the other slot so for a few minutes there were 2 redundant supplies. 

My issue is I am back to a single power suuply (not a mission critical server), but my Open Manage keeps registering alerts below:

PS 2 Status power supply sensor removed
BMC PS Redundancy sensor redundancy lost

I know I only have one power supply there but the alerts and the bix red warning in IT Assistant are alrming when doing a quick system check to be sure everything is ok.

Can anyone tell me how I can convince the system that there is only one power supply again?

DRAC 4/i - Firmware 1.75

BMC 1.83 if either of those matter.

Thanks for any help you can provide,

Scott
