Installing the T1600 Mounting Hardware for an Open-Frame Rack
If you are installing the router into an open-frame rack, you must first install the large
mounting shelf on the rack. If you are front-mounting the router, you must remove
the center-mounting brackets from the chassis. The small mounting shelf and the
spacer bars are not needed.
Table 1 specifies the mounting holes in which you insert the mounting screws (an X
indicates a mounting hole location), and cage nuts if needed. 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 1):
1. Install cage nuts, if needed, in the mounting holes specified in Table 1.
2. On the rear of each rack rail, partially insert a mounting screw into the lowest
hole specified in Table 1 for the large shelf.
3. Install the large shelf on the rack. Rest the bottom slot of each flange on a
mounting screw.
4. Partially insert screws into the open holes in the flanges of the large shelf.
5. Tighten all the screws completely.
6. Remove the mounting brackets from the chassis by loosening the screws at the
top and bottom of each bracket.
The router is shipped with each spacer bar attached to the rear of each front-mounting
flange. Remove each spacer bar by removing the screws that fasten the spacer bar
to the front-mounting flange.
