Installing the MX480 Router Mounting Hardware for a Rack or Cabinet
The router can be installed in a four-post rack or cabinet or an open-frame rack. Install
the mounting hardware on the rack before installing the router.
Install the mounting shelf, which is included in the shipping container, before installing
the router. We recommend that you install the mounting shelf because the weight of a
fully loaded chassis can be up to 163.5 lb (74.2 kg).
Table 23 on page 65 specifies the holes in which you insert cage nuts and screws to install
the mounting hardware required (an X indicates a mounting hole location). The hole
distances are relative to one of the standard U divisions on the rack. The bottom of all
mounting shelves is at 0.02 in. above a U division.
Table 23: Four-Post Rack or Cabinet Mounting Hole Locations
Mounting Shelf Distance Above U Division Hole
X 1.14 U 2.00 in. (5.1 cm) 4
X 0.86 U 1.51 in. (3.8 cm) 3
X 0.50 U 0.88 in. (2.2 cm) 2
X 0.14 U 0.25 in. (0.6 cm) 1
To install the mounting shelf on the front rails of a four-post rack or cabinet, or the rails
of an open-frame rack:
1. If needed, install cage nuts in the holes specified in Table 23 on page 65 .
2. On the back of each rack rail, partially insert a mounting screw into the lowest hole
specified in
Table 23 on page 65 .
