There is an 8-Digit Error Code
You have an 8-digit error code in the form 10n1 xxxx and
n is greater than the number of I/O drawers in the
system.
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 U0.n. Substitute 2 for n when looking up the
error code in “Checkpoint and Error Code Index” on page
161.
You have an 8-digit error code of the form 10n1 xxxx and
two or more drawers have the same drawer number.
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
110 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 “Checkpoint and Error Code Index” on page
161.
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.
You have an 8-digit error code. Look up the error code in the table in “Checkpoint and
Error Code Index” on page 161.
