Note
If a PCU without its own OP/TP including TCU is switched off and then back on, and if this is
to be followed by the power up of the PCU of the service system (EBS), an external screen
and keyboard are needed to operate the PCU.
An external screen and keyboard are not needed if the TCUs are operating and the PCU is
not switched off with the EBS during booting.
