Chapter 5 Chassis Installation
CPX8216 and CPX8216T Installation and Use (6806800A52C)
37
Installing the Chassis in a Frame Relay Rack/Cabinet
The CPX8216 chassis can be mounted in either a 19" or 23" Frame Relay rack/cabinet, which
are common in Central Office locations. In this configuration, the CPX8216 is held along the
center of the rack with optional mounting brackets, providing a balanced weight distribution on
the chassis and aiding in reliability of the chassis when subject to earthquake, shock, or
vibration.
A separate mounting bracket kit is required to attach the CPX8216 chassis to the Frame Relay
rack/cabinet. The same kit is used for either 19" or 23" wide racks/cabinets. The kit includes four
(4) mounting brackets and 16 screws (10-32). Kits can be ordered from your local Emerson
sales office or distributor.
The installation steps are listed below.
1. Locate the correct mounting holes by positioning the bracket against the rack and line up the
four vertical mounting holes.
Note This step should be performed before attaching the brackets to the chassis.
2. Attach two front mounting brackets to the front mounting holes located on the sides of the
CPX8216 chassis (see the figure on page 38). Use a torque setting of 7 in.-pounds.
For 19" racks, the long side of the bracket should be fastened to the chassis
For 23" racks, the short side of the bracket should be fastened to the chassis
!
Warning
Warni ng
Do not mount the chassis at the top of the rack. A top-heavy rack can tip, causing
damage to equipment and injury to personnel.
Two people should perform the following procedure to avoid personal injury or
damage to the equipment.
3. Slide the CPX8216 chassis into the front of the rack.
4. Attach the chassis to the rack using eight Phillips head screws that came with the bracket kit.
Do not tighten these screws until the back brackets are installed. Be sure to mount the chassis
with metal screws or bolts that give a good electrical connection between the screws or bolts
and the mounting surface.
Note Failure to observe proper grounding practices may cause a variety of noise, electrostatic
discharge, and RFI (Radio Frequency Interference) problems.
