Hi Mark,

I have seen this before and we found it was the LCD display cable had worked loose, reseating the cable resolved the issue. It may not be the same problem you are having though. Its cable 2 on diagram 3-25 on the link below:


Its best to be careful though, the cable connects to a ZIF socket and they can be delicate.

Yeah, I've gone through the three options (None, Default, User-Defined) and they don't change anything. Ctrl-E doesn't have any related options.

The 1950 next to it in the rack (they should be the same hw config) is showing a PSU Redundancy failure with one PSU unplugged, so this server should do the same.

Any other ideas? I see a little reset(?) switch that looks like it needs a paper clip to use - is that a real system reset or does it do the LCD by any chance?
