Troubleshooting 3-41
The SRM show fru command identifies a few more FRUs than the SCM show
fru command. See Table 3–8 for an explanation of the fields displayed by both
commands, and Table 3–9 for additional units identified by the SRM.
Table 3– 9 Additional SRM Show FRU Codes
Field Description
FRU The field-replaceable unit name and location in the hierarchy of the system.
CABx Cabinet, - pwr, rack, sys RAKx Power subrack
PSx
Power supply in either a
power subrack or PCI box
SYSFAN or
SYSFANx
Blower in system cabbinet
Fan in PCI box
PCIx
PCI slot of identified
device
CLKSPLT Clock splitter module
Example 3– 22 Set sys_serial_number
P00>>> set sys_serial_num NI900100023
P00>>>
All FRUs that have an EEPROM contain a copy of the system serial number.
An error, 80 in the error field, is recorded if the system serial number in the
FRU differs from the system serial number contained in the EEPROM on the
standard I/O module controlling the partition. When the set sys_serial_num
command is executed, all FRUs that have an EEPROM in the partition are
blasted with the system serial number. Therefore, every time you replace a
FRU that has an EEPROM you’ll want to execute the set sys_serial_num
command.
