Installing the MX960 Mounting Hardware for a Four-Post Rack or Cabinet
Before installing the router in a four-post rack or cabinet, install the large mounting shelf, followed by the
small mounting shelf. You must also remove the mounting brackets from the chassis.
Table 109 on page 255 specifies the holes in which you insert cage nuts, if needed, and screws to install
the mounting hardware required in a four-post or cabinet rack (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.

To install the mounting shelves (see Figure 56 on page 257):
1. On the front rack rails, install cage nuts, if needed, in the holes specified in Table 109 on page 255 for
the large shelf and the spacer bars.
2. On the front of each front rack rail, partially insert a mounting screw into the hole containing the lowest
cage nut.
