Task Description
Disconnect the ribbon cables from the sockets at the top of the Power Interface Circuit Board, and
carefully set them aside.
Carefully disconnect fiber-optic cables from sockets along the right-hand side of the Power Interface
Circuit Board, and carefully set them aside.
Disconnect the other cables from the sockets on the Power Interface Circuit Board, and carefully set them
aside.
Remove the five M3x6 Phillips screws, which secure the Power Interface Circuit Board to the Control
Frame, and remove the circuit board.
Proper tightening torque for reassembly is 0.9 N•m (8 lb•in).
Remove the Power Interface Circuit Board from the Control Frame.
ATTENTION: Hazard of permanent eye damage exists when using optical
transmission equipment. This product emits intense light and invisible
radiation. Do not look into fiber-optic ports or fiber-optic cable connectors.
Minimum inside bend radius for fiber-optic cable is 25.4 mm (1 in.). Any
bends with a shorter inside radius can permanently damage the fiber-optic
cable. Signal attenuation increases with decreased inside bend radii.
Before removing connections and wires, mark the connections and wires to
avoid incorrect wiring during assembly.
