Mounting Brackets
The following mounting brackets are available:
•
19-inch frame (this bracket is part of the CN 3960 kit)
•
23-inch frame
•
ETSI frame
To obtain the orderable part numbers for the optional brackets See
Table 1-10, on page
19.
There are three threaded holes on the side of the chassis. You attach the mounting
brackets using two of the three holes. The CN 3960 can be mounted in either front or
mid-mount position.
The orientation of the bracket, and the choice of mounting holes used, dictates the final
placement of the unit within the frame. The following placement options are available:
•
Front Mount (using the front two holes) — unit is flush with the front of the frame
•
Front Mount (using the back two holes) — unit is 46 mm (1.8 inches) in front of the
frame
•
Mid-mount (using the front two holes) — unit is 81 mm (3.2 inches) in front of the frame
•
Mid-mount (using the back two holes — unit is 127 mm (5 inches) in front of the frame
