SRC Help - D100 C0FF

["Walden H. Leverich" <WaldenL@xxxxxxxxxxxxxxx>]

I came in this morning and our iSeries (270) was off. No System
Attention light, just off. Strange I thought, and IPL'd it and went to
my desk. Came back 10 minutes later and, um, it was off. Again, no SA
light. I did a lamp test and the SA light works fine, so I IPL'd it
again, and again it was off. So this time I watched the SRC codes during
boot. 
 
I get the C100.... messages then into the C600... messages. I get a C600
4015, 4016, 4023 and finally 4027. Then... a couple of really quick SRC
code changes and it lands on D100 C0FF. I can't find a reference to D100
C0FF anywhere (besides the obvious point that the last 3 characters
spell OFF.) 
 
I've tried to boot in normal and manual mode w/OpsConsole, but OC
connects just before the D100 C0FF SRC code shows up, so I can't really
see anything.
 
Anyone familiar with D100 C0FF?
