Thus spake Steve Valiunas
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...
What's the actual SNMP OID for this? I think I remember seeing it somewhere, but I'll be darned if I can find it now. Aha! Just found it. In the NMC-MIB, nmcStatRedLed nmcStatRedLed OBJECT-TYPE SYNTAX INTEGER{ none(1), chassisTemperatureHigh(2), chassisFanFailure(3), voltageWarningforPSU(4), failureofPSU(5), managementBusFailure(6), interfaceCardFailure(7), incompatibleTokenRingNIC(8) } ACCESS read-only STATUS optional DESCRIPTION "This Object will return the Reason why the Hub Status LED is RED." ::= { nmcStat 12 }
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.
Well...considering the older style add-on tray didn't have any connection whatsoever to the chassis, that makes sense. ;) -- 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.
