Behavior at Occurrence of Error

In this manner, the server retries POST or OS startup with different combinations of CPU/IO
modules. If POST does not finish normally with any combinations, the server will stop with the
state of DC OFF or Post end with an error message displayed.

when the server was last shut down or how the power cables were connected.
The following devices are connected to the primary CPU/IO module by a hardware switch, although
they can be connected to both CPU/IO modules 0 and 1. When the primary CPU/IO module is
disconnected they are switched to the secondary module automatically and continue operating.
