13.3 Minimum startup configuration
If the server does not start up or other problems occur, it may be necessary to
take the system down to its most basic configuration in order to isolate the
defective component.
The minimum startup configuration consists of the following components and
cables:
Ê Shut down the server, see section "Shutting down the server node" on
page 50.
Ê Take the system down to its minimum startup configuration.
Ê Connect a keyboard, mouse and display to the server.
Ê Switch on the server, see section "Controls and indicators on the server
node" on page 448.
V CAUTION!
Since the fan module is not included in the minimum startup
configuration, the server must be shut down immediately after the
diagnostic process is complete (POST phase has been passed).
