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

[Stanley_Riley_J]

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.

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,

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.

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.
