v See Chapter 4, "Parts listing, Types 7871 and 1949," on page 41 to determine which components are CRUs and
which components are FRUs.

Error code Description
405-906-xxx Failed MAC layer loopback test.
405-908-xxx Failed LED test.
Action
1. Make sure that the component firmware level is
up-to-date, upgrade if necessary; then, rerun the
test. The installed firmware level can be found
in the DSA Diagnostic Event Log within the
Firmware/VPD section for this component. The
latest level firmware for this component can be
found on the IBM support Web site at
http://www.ibm.com/support/
docview.wss?uid=psg1MIGR-63017.
2. If the failure remains, check interrupt
assignments in the PCI Hardware section of the
DSA Diagnostic Log. If the Ethernet device is
sharing interrupts, modify the interrupt
assignments using the Setup utility to assign a
unique interrupt to the device (see "Using the
Setup utility" on page 20).
3. If the failure remains, refer to Chapter 5,
"Removing and replacing blade server
components," on page 49 to replace the failed
component.
