Connect a Serial cable and run 'racadm help config -g cfglannetworking' for examples on changing DHCP status or IPs.

What is needed if I encounter CMC self test failures via Serial connection?

Physically remove and reinsert the CMC in the chassis, as there are no serviceable components to fix it.

Use the RACADM command 'getversion' or go to Chassis Overview → Update (in the Web Interface).
