OLS/Power Unit Query Test (#127)
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). See CARR-POW (Carrier Power Supply)
