UCS Chassis I/O problems

[clyded]

:                         Anyone  else having Cisco UCS 6140/5108 chassis problems that cause the fans to  act up  and the I/O card to have power and temp alarms ver1.3.0 even  when the environmental conditions are OK?

Firmware 1.4(2b) fixes the thermal and fan issues.

We had to power cycle the chassis to clear the issues up (not something you want to have to do in a data center) .  The I/O module is fine and the fans are normal again.  My thoughts were a code issue too, but the "fix" code is only a couple weeks old...

It is a very stable release, I have updated 4 of my customers to 1.4(2b) and haven't had any issues.

FYI there are a couple of fixes in this release for these problems.   I believe the problem you are describing is related to this, which is part of the release discussed.
