Gen 3 Site Controller System Manual Chapter 3 Pre-Installation
Site Planning
19 Inch Rack
The front panel of the site controller and EAS/EAS2 is 19” wide to allow for
installation into 19” wide cabinets. The site controller and EAS/EAS2 are
typically installed into a 19” wide cabinet prior to shipment.
23 Inch Rack
Hardware is available to allow for installation of the site controller and EAS/
EAS2 into either a larger 23” wide cabinet or a three, five or six inch deep
rack. The cabinet type is a Cabtron Systems, Inc. cabinet supplied as part of
the Power Conversion Products DC Power System.
The Field Replaceable Unit for the hardware is CLN1680A. Hardware is
contained in the sub-kit, CLN7694A. The CLN7694A kit contains 2 main
brackets and 4 angle brackets. The angle brackets are mounted to the main
brackets with M4 screws. Placement of the angle brackets on the main
brackets is adjustable to fit rack depths of 3-inches, 5-inches or 6-inches
(Figure 3-2) as well as Cabtron cabinets (Figure 3-3).
The CLN7694A kit also contains both 10-32 and 12-24 screws to attach the
angle brackets to the cabinet or rack. Both sizes are common in racks.
Choose the correct screw for the rack being used, or use screws provided by
the cabinet or rack supplier.
A ground bracket to which a static strap can be attached is also provided.
This bracket should be placed, where convenient, under one of the Junction
Panel mounting screws.
Only a trained technician who is familiar with the installation of electronic
infrastructure or similar type equipment should perform the following
procedure:
Installation of the site controller/EAS/EAS2 in a Cabinet/Rack
1. Determine the correct position for mounting the 4 angle brackets to
the 2 main brackets based on dimensions of the cabinet/rack. Attach
the angle brackets using M4 screws (12 places).
2. Attach the assembled brackets in the cabinet or rack using the
appropriate hardware provided, or hardware provided by the cabinet
or rack supplier (16 places). For the Cabtron cabinet, attaching angle
brackets to both the front and rear cabinet rails is preferable. For
racks, it is desirable to attach angle brackets to both the front and rear
of the rack.
