Installing the Mounting Hardware for a Center-Mount Open-Frame Rack
If you are installing the router in a center-mount open-frame rack, you must first install
the large mounting shelf on the rack. The spacer bars are not needed for this mounting
option; however, you can leave them attached to the front-mounting flanges.
Table 66 on page 121 specifies the holes in which you insert screws to install the mounting
hardware in an open-frame rack (an X indicates a mounting hole location). 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.
