Problem with Fabric Module 2 in Nexus 7010

 

Hi, I’ve got this problem with my N7K and 2 of the fabric module’s.  The front LED of the N7K is yellow/orange instead of green (it’s supposed to be green I believe).  Not sure what this relates to, hw issue, config issue or?

As you can see below, 2 of the fabric module are powered down.  Restarting the fab’s og restarting the N7K does not power up the fab module’s.

Are you sure the switch hasn't been configured this way?

You can manually power down the fabics in order to minimise overall power by using the command poweroff xbar. See below:
