UCS manager is displaying LINK failure or not-connected

[Ayham]

Recently we found on the FI -B (primary), one of the Server type Interface, is down with Error F0276 

we tried to change the cable , un-configure/reconfigure but no solution 

The SFP port is  Cisco-Molex 74752-95521 

FI-B -> Port 1/14 -> chassis 1 /2/3 

what should we do? should acknowledge the UCS chassis?

Depending on the UCSM firmware version, you can re-ack the specific IOM and not the whole chassis.

If that doesn't resolve, I would open a TAC case.

There are logs in IOM (inside chassis tech support) that may help ID if this is an issue with IOM, and UCSM tech support will help ID if this is related to an issue with FI, etc.

I'm assuming the 'show int eth 1/14' on FI B nxos doesn't contain any considerable errors in counters?

 What UCSM infrastructure firmware version are you running?
