The SP comes up in degraded mode with no Active SP and a very limited
command set as most features are disabled (FMA, start/stop/reset/show).
Example:
-> reset /SP
reset: Target /SP cannot be reset
Unrecognized Chassis: This module is installed in an unknown or unsupported
chassis. You must upgrade the firmware to a newer version that supports
this chassis.
After platform AC power cycle see no change. After a while SP is reachable but no Active SP and is in degraded mode.
Running most commands to manage the platform comes back with "Unrecognized Chassis". Same status as when reset the SP.
