Installing the MX240 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 128 lb (58.1 kg).
Table 1 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 0.04 in. (0.02 U) above a “U” division.
Table 1: Four-Post Rack or Cabinet Mounting Hole Locations
Hole | Distance Above U Division | Mounting Shelf | |
|---|---|---|---|
4 | 2.00 in. (5.1 cm) | 1.14 U | X |
3 | 1.51 in. (3.8 cm) | 0.86 U | X |
2 | 0.88 in. (2.2 cm) | 0.50 U | X |
1 | 0.25 in. (0.6 cm) | 0.14 U | X |
To install the mounting shelf on the front rails of a four-post rack or cabinet, or the rails of an open-frame rack:
- If needed, install cage nuts in the holes specified in Table 1.
- On the back of each rack rail, partially insert a mounting screw into the lowest hole specified in Table 1.
- Install the small shelf on the back of the rack rails. Rest the bottom slot of each flange on a mounting screw.
- Partially insert the remaining screws into the open holes in each flange of the small shelf (see Figure 1 or Figure 2).
- Tighten all the screws completely.
