x460-48p error 5: fan failing / operational again over and over in the log


Userlevel 2
Hello, Has anyone seen these types of errors? We are seeing these in the log for both switches in a 2-switch stack. Is it really possible that 2 switches are having similar fan problems at the same time? 05/15/2015 10:39:17.80 Slot-2: Slot-2, Error 5: Fan #4 in slot 2 operational. Rpm 3485 is back to operating range (from 2320 to 8050 rpm). 05/15/2015 10:39:17.79 Slot-2: Slot-2, Error 5: Fan #3 in slot 2 operational.

Stanley,

What is the physical status of the fan when the failure messages are occurring? What is the status of the fan LED? What version of EXOS? I would also suggest reaching out to GTAC so we can troubleshoot further and identify the issue.

Take a look at the following article to see if it addresses it....

Joshua, I'm not physically at the location, so I'm having my site lead check the LED. The EXOS version is 12.5.4.5 patch 1-4.

Stanley,

Have these fans been recently pulled and reinserted? Were there any recent changes? Also please note that the recommended release for a Summit X460 is 15.5.3.4-patch1-5.

Stanley,

Thank you for that information. I would suggest calling into GTAC so we can open a service request and troubleshoot the issue further and determine a resolution.

ok, will do. Thank you very much for your time today. 🙂 Actually, one more question, are the fans in the x460 replaceable, or does the whole switch need to be replaced? I'm trying to plan my next steps.

Stanley,

The Summit X460 fans are modular and can be replaced.

Whew, no rebuilding of the stack then. That's good for me. 😉

Sorry to bring this up again, but I need to retrieve the fan serial numbers for GTAC. They suggested running sh fan det, but that doesn't show any serial numbers. Is there a different place I can check? Please keep in mind that I'm currently running XOS 12.5.4.5patch1-4. Thanks for any tips.

We got it. It is due to the version of XOS we are running there. We just pulled the fans and took pics of the serials. lol
