Juniper Control System (JCS) 1200 Platform Hardware Guide
Installing the JCS 1200 Mounting Hardware for an Open-Frame Rack
If you are installing the JCS 1200 platform in a front-mount or center-mount
open-frame rack, you must first install the large mounting shelf on the rack. The
small mounting shelf is not needed.
For information about the holes in which you insert mounting screws (and cage-nuts
if needed) to install the mounting hardware in an open-frame rack (an
mounting hole location), see "Rack Mounting Hole Locations for the JCS 1200
Platform" on page 43. The hole distances are relative to one of the standard U
divisions on the rack. For reference, the bottom of all mounting shelves is at
0.04 in. (0.02 U) above a U division.
To install the large mounting shelf (see Figure 22 on page 47):

If the rack rails require cage nuts, install cage nuts into the holes specified for
the large shelf on the rear side of the rack rails.
If the rack rails require cage nuts, install cage nuts into the holes specified for
the chassis on the front side of the rack rails
On the rear of each rack rail, partially insert a mounting screw into the highest
hole specified for the large shelf.
Install the large shelf on the rack. Hang the shelf over the mounting screws using
the keyhole slots located near the top of the large shelf flanges.
Partially insert screws into the open holes in the ears of the large shelf.
Tighten all the screws completely.
Attach the mounting brackets to the sides of the chassis:
If you plan to front-mount the chassis in an open-frame rack, attach the
front-mounting brackets using six of the mounting screws provided.
If you plan to center-mount the chassis in an open-frame rack, attach the
center-mounting brackets using the eight mounting screws provided.
