The NMC can be queried to tell you the reason for the Hub-Status light
being red- It's under Performance Monitor / FuncGroup=FailureReasons /
Parm=HubStatusRed. This is available on TCS3.5 and later codes (nmc ver 6.x.x).
It might be a high temperature, a card being reset, some kind of non-critical
failure on the NMC, a bad PSU...
The oldstyle chassis with the fan in the back has a sensor for the single
fan, and the newer-style chassis with the built-in fan tray will report failures
for the tray. You probably won't get anything for the older add-on fan tray
though.

Dunno...haven't checked that closely...but I do know that there is a
trap enable for fan failures, as well as an auto-response script, so I'm
pretty sure they are instrumented. I'll pull a fan tray to see if I can
tell if I think about it today.
