3.3.1 Checking the Hardware Configuration and FRU
Status
To replace a faulty FRU and perform the maintenance on the server, it is important
to check and understand the hardware configuration of the server and the state of
each hardware component.
The hardware configuration refers to information that indicates to which layer a
hardware component belongs.
The status of each hardware component refers to information on the conditions of a
standard or optional component in the server: temperature, power supply voltage,
CPU operating conditions, and other status information.
To check the hardware configuration and the status of each hardware component,
use XSCF shell commands from the maintenance terminal. See
TABLE 3-1
for the
commands used.
