PowerEdge 2650 "Rembrandt" error message

My Poweredge  2650 has recently started scrolling the word "Rembrandt" on its front LCD status display. While it was initially only an information message, it has now changed to a message that requires action.

I have been unable to find any information about what the "Rembrandt" message means, so I am unable to do anything to address the error. Power cycling the server makes no difference. The message did go away for a while after I changed some RAM in response to another message, but it has now returned.

Can anybody help me or direct me to further information?
