Have you tried just admin down and admin up them?

Hi lucifer6

There could be couple of issues leading to port down, we can always begin narrowing this down by;

Reseat the cables and the SFP that goes in port <portname> on controller side, replace cable/SFP
Check connection with the switches.
Reseat cable on switch port, replace cable/SFP
Try other switch ports to confirm connectivity

Did they plug into the right node? Have them check serial # on the system's chassis and confirm it is the right one.

Cabling and switch config. That's about it i think that's left to check.

Hi,

So those are UTA ports, have you configured them properly ?

" ucadmin show " command will give you the port configuration.

Aman

You can check controller ports, reinsert ports, replace cables,

check switch ports and cables,

or try controller ports to test with other switch ports
