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.
