Fault clearing procedures

System messages with the mnemonic PWR (power) contain four fields of
information about power equipment. These fields identify the type of
equipment indicated (such as the blower unit) and the source of the message
(system monitor, module, or module power supply). Table 7 defines the fields
in PWR messages. Figure 4 shows the power equipment identified in PWR
messages.
