FAIL AC-POWERED SYSTEMS
There is a problem with one or both OLSs on the tested carrier.
1. For each OLS that has every status LED OFF, check the AC input to
the OLS at the OLS outlet. If there is no AC, then check the
appropriate fuses for the affected OLS. Replace open fuses. If the
fuses open again or AC does not show up at the OLS outlet, then
there is probably a power wiring problem in the cabinet.
2. At this point, AC should be present at the OLS outlet. Enter recycle
carrier UUC, where UUC is the appropriate cabinet and carrier, in
an attempt to bring back the OLSs for this carrier. If the test passes,
the trouble is cleared. If the test does not pass, one OLS or both in
the tested carrier is defective. If only one OLS is defective, then the
status LEDs on the healthy OLS will light green for a moment. When
the recycle test determines that both OLSs are defective, the
software will turn off power to both the good and defective OLSs. This
will cause the status LED(s) on the good OLS to light red.
3. Unplug both OLSs, and wait approximately 1-minute to allow the
OLSs to cool down. Plug in the OLSs. If either OLS is operating
properly (the status LEDs show green), replace the defective OLS(s).
