FAIL
There is currently a problem with the environment of the power system.
1. The power supply to any one of the carriers may have been lost.
a. Verify, and if necessary restore, AC power at the wall 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 defective.
a. If the yellow status LED on a WP-91153 or 676-B power unit is off,
replace the power unit. See
Maintenance Procedures (03-300192).
b. Rerun the test. If the test still fails, proceed with Step
3. The PN’s MAINT (Maintenance circuit pack) could be incorrectly
reporting this error. Resolve every alarm on these MOs, and rerun the
test. There are failures that can occur on the PN’s Maintenance circuit
pack that will not be detected by their respective maintenance, but that
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 escalation procedures.
