Table 3– 8 Show fru Command Field Descriptions
Field Description
FRU The field-replaceable unit name and location in the hierarchy of the system.
QBB Quad building block PSM Power system manager
CPU CPU module PWR Main power module
MEM Memory module AUX Auxiliary power module
DIMM DIMM module IOxx Local I/O riser (xx=ports)
DIR Directory module GP Global port
HSW8 8-port H-switch HPM H-switch power manager
PBP PCI backplane SIO Standard I/O module
RIO Remote I/O riser module
E Error field. Indicates errors logged against the FRU. Codes are as follows:
01 Failure 10 Checksum error on bytes 0-62
02 Test detected error logged 20 Checksum error on bytes 64-126
04 At least one error logged 40 Checksum error on bytes 128-254
08 reserved 80 FRUs system serial #s inconsistent
Part # The Compaq or vendor part number of the FRU in ASCII.
Serial
#
The FRU serial number. For Compaq parts the serial number format is:
XXYWWNNNNN, where XX = manufacturing location,
YWW = year and week, and NNNNN = sequence number in hexadecimal.
Model/
Other
Optional model information about the module. For example, for FRU PBPx the
field might read PCI_BACKPN.
Alias Optional name for the FRU.
The show fru command, Example 3–7, reads the EEPROM on each FRU.
Table 3–8 describes each field. The SCM clear error <fru> command clears
the error field of the target FRU (see Example 3–8).
