1 FAIL There is currently a probl em with the environment of the powe r system.
1. The power supply to any one of the carriers may have been lost.
a. Verify, and if nec essary restore, AC power at the w all outlet for each
carrier.
b. Rerun the test. If the test still fails, proceed to Step 2.
2. One of the WP-91153 or 676-B power units for one of the carriers could
be defect ive.
a. If a WP-91153 or 676-B power unit does not have its yellow status
LED on, then replace the power unit (procedure in Chapter 5,
‘‘Alarms, Errors, and Troubleshooting’’).
b. Rerun the test. If the test still fails, proceed with Step 3.
3. 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 EPN Maintenance circuit
pack that
will not
be detected by their respective maintenance, b ut
which will cause many, if not all, environment tests to fail. If more than
two environment tests are failing, the suspect circuit pack, depending
on the system configuration, should be replaced and the test rerun. If
the test still fails, follow normal es c alation proced ures.
PASS The MAINT (EPN Maintenance Circuit Pack) has reported no problem with
the power.
