Installing CRPC/ROP Frames
DCM
1. A CRPC/ROP frame should be installed below the bottom-most subrack inside a
cabinet.
2. Reserve 2 U (89 mm) space above the CRPC/ROP frame for ventilation
purposes. To ensure proper ventilation of the frame, do not place any device
around the air intake and exhaust vents of the frame.
NOTE
Position and attach a
mounting ear to the side of
the CRPC/ROP frame,
securing it to the CRPC/ROP
frame with appropriate
screws. Repeat this step to
attach a mounting ear to the
other side of the CRPC/ROP
frame.
Position the CRPC/ROP
frame in the cabinet and
attach the mounting ears
to the cabinet columns
with four panel screws,
two screws on each side.
