12.3 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
"Shutting down the server node" on page 40
Ê
"Disconnecting the power cord" on page 41
Ê
Take the system down to its minimum startup configuration.
Ê
"Connecting the power cord" on page 71
Ê
"Switching on the server node(s)" on page 72
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).
The minimum startup configuration must be used exclusively for
diagnostic purposes by maintenance personnel, never in daily
operation!
