CARR-POW (Carrier Power Supply)
Off-Line Switcher (OLS) Query Test (#127)
This test queries the the EPN's Maintenance for the status of the pair of OLSs in
the specified carrier. If both OLSs are on and functioning, then the test passes. If
both are not on and functioning, it fails.

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.
