NOTE:
The problem may be in the backplane wiring of the DDM-2000. One way
to verify this is to swap the SYSCTL and any circuit pack with an
inconsistent diagnostic indication with the corresponding circuit packs in
another DDM-2000. If the problem moves with the circuit packs, it means
that one or more of the circuit packs is defective. If the problem stays with
the original DDM-2000, the entire assembly, but not the circuit packs,
should be replaced. The DDM-2000 has a printed backplane and cannot
be repaired in the field.
NOTE:
A CIT and the system rtrv-( ) commands may be helpful in
determining the condition of the system.
Use CIT and rtrv-alm: command to get an alarm and status report. See the
COMMANDS AND REPORTS section of this manual under RTRV-ALM for a
description of each message retrieved with the rtrv-alm: command.
If you need technical assistance, notify your supervisor, your local technical
support organization, or call Lucent Technologies RTAC, per local operating
instructions.
12. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
