Error Number Table Description
Error # column: Contains the error number that is printed as part of the
failure report of the srom/xsrom test. “Error: xxxx”
FRU column: Lists the possible FRU(s).
Component(s) column: Lists the possible failing components associated with
the FRU(s) called out in the FRU column.
For example, if a callout were FRU1: QBBx.CPUy EV, BCache where
• QBBx (x=0,1,2,3,4,5,6,7) represents the QBB backplane,
• CPUy (y=0,1,2,3) represents the CPU in that QBB,
• EV represents the Alpha Processor as the possible failing component, and
• BCache represents the Backup Cache (on the CPU module) data RAM as
the possible component.
Or if a callout were FRU1: QBBx.MEMy.DIMMz, where
• QBBx (x=01,2,3,4,5,6,7) represents the QBB backplane
• MEMy (y=0,1,2,3) represents the Memory module in that QBB
• DIMMz (z=0,1,2,3,4,5,6,7) represents the failing DIMM on that Memory
card
NOTE: If either the “FRU” or “Component” column is left blank, the field is the
same as the callout for the previous error # directly above it.
