STEP PROCEDURE
Wear ground straps according to local office procedures.
Ensure the two mounting screws, accessible through the front panel,
are loosened before attempting to remove power supply from shelf
to prevent breaking handle.
Mounting surfaces on both power supply and heatsink must be
clean to ensure proper heat transfer. Mounting screws must be
torqued to 19 in. lbs.
This is an out-of-service procedure when on a nonstandby (unpro-
tected) system. On a hot-standby or frequency diversity system, switch
