EXOS is 12 version - but Customer have no access to newer version.

Any ideas?
Can it be RMA case? Because X350 is still have valid warranty.

Thank you!

Hi Alexandr!

Request customer to perform switch diagnostic with the command .
If some tests fail then open RMA.

BR,
Nikolay

Try removing all SFP's, reboot the switch and put them back in one by one. Maybe one of the SFP's is causing a hang on the i2c bus ?

Hello, Oscar!

There is no any SFP's in this switch - all ports don't working (with the exception of 10Gig ports).

Thank you!

i think it is then time to replace/RMA the switch. You can try an upgrade but I doubt it will resurrect the ports.

"@@@ system detail" from the "show tech detail" output may contain some info about the issue. Looks like the problem is with phy for combo-ports and most of all it is a RMA.
