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.
PASS
The PN’s MAINT (Maintenance circuit pack) has reported no problem with 
the power.
