SRN FRU List % Problem
300C0 Backplane 100 Description: A disk drive module has
detected the loss of one of its power
inputs.
Action:
If the failing device is an SSA
Hot-Swap Disk Drive, exchange the
backplane.
If the failing device is not an SSA
Hot-Swap Disk Drive, go to the
service information for that device.
301C0 Backplane assembly 100 Description: Multiple disk drive modules
have detected the loss of one of their
power inputs.
Action:
If the failing devices are SSA
Hot-Swap Disk Drives, exchange the
backplane.
If the failing devices are not SSA
Hot-Swap Disk Drives, go to the
service information for those devices.
303FF Disk drive module 100 Description: An SCSI status that is not
valid has been received.
Action: Go to “Software and Microcode
Errors” on page A-5 before exchanging
any FRUs.
40000 SSA adapter card 100 Description: The SSA adapter card has
failed.
Action: Exchange the FRU for a new
FRU.

Description: An SSA device on the link is
preventing the completion of the link
configuration.
Action: If the SSA service aids are
available, run the Link Verification service
aid to determine which device is
preventing configuration. (That device is
the one beyond the last-configured device
on an open SSA link.)
44PAA Disk drive module 100 Description: A disk drive module has
failed.
Action: If the SSA service aids are
available, run the Link Verification service
aid to find the failing disk drive module.
Before you exchange the failing disk drive
module, run diagnostics in the system
verification mode to the module to
determine the cause of the problem.
