2029 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5
times.
1 FAIL There is a problem with the environment of the power system.
1. The power unit for any one of the cabinets may have been
lost.
a. Verify and, if necessary, restore power units for each
cabinet.
b. Rerun the test. If the test still fails, proceed to Step 2.
2. Either the WP-91153 AC power unit or the 676B DC power
unit for one of the cabinets could be defective. Refer to the
“Removing Power” and “Restoring Power” sections in
Chapter 5, “Routine Maintenance Procedures”.
a. If the yellow LED on the WP-91153 AC power unit or the
676B DC power unit is off, replace the power unit.
b. If the Active Tone-Clock circuit pack loses power, the
system performs a Cold-2 restart to finish (the login
prompt appears at the administration terminal).
c. Rerun the test. If the test still fails, proceed with Step 3.
3. The DUPINT (Duplication Interface Circuit Pack), or the
MAINT (EPN Maintenance Circuit Pack) could be incorrectly
reporting this error. Resolve all alarms on these MOs, and
rerun the test. There are failures that can occur on the
Duplication Interface and EPN Maintenance circuit pack that
are not detected by the respective maintenance, but that
cause many, if not all, environment tests to fail. If many
environment tests are failing, the suspect circuit pack,
depending on the system configuration, should be replaced
and the test rerun.
PASS The DUPINT (Duplication Interface Circuit Pack), or the MAINT
(EPN Maintenance Circuit Pack) has reported no problem with
the power.
