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.

Walk the uchasPowerSupplyTable for information about the power supplies, and, unfortunately, it seems that there is no OID to find out about fan failures...3Com, is there a possibility that this can be added? Obviously, they are instrumented as you can get traps on fan failures and auto-response scripts for fan failures...
Aren't the fans in the fantray two wire? I don't think two wire fans can be tested for failure, like the new three wire PC chassis and CPU fans.
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. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
