Service Guide
Action
The failing drawer is drawer n . Look for the
drawer with the same value of n in its operator
panel, either in the form *0n or U0n. Substitute 2
for n when looking up the error code in
"Checkpoint and Error Code Index" on
page 165.
Shut down the system and remove all but one
of the drawers with duplicate drawer numbers.
Refer to the steps in "MAP 1540: Minimum
Configuration" on page 113 for a procedure to
connect/disconnect I/O drawers. Attempt to
reboot the system.
1. If the system still fails, you have found the
failing drawer. Substitute 2 for n when
looking up the error code in Go to
"Checkpoint and Error Code Index" on
page 165.
2. If the system boots, shut down and add
another of the detached drawers back into
the system. Repeat steps 1 and 2 until the
failing drawer is isolated.
Note: As the system successfully boots,
duplicate drawer numbers are resolved into
unique drawer numbers.
Go to "Checkpoint and Error Code Index" on
page 165.
