Installing a Mounting Shelf in a Rack or Cabinet for an EX9208 Switch
The switch can be installed in a four-post rack or cabinet or in an open-frame rack. Install
the mounting hardware on the rack before installing the switch.
We recommend that you install the mounting shelf, which is included in the shipping
container, before installing the switch because the weight of a fully loaded chassis can
be up to 163.6 lb (74.2 kg).
Table 65 on page 162 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.

To install the mounting shelf on the front rails of a four-post rack or cabinet, or on the
rails of an open-frame rack:
1. If needed, install cage nuts in the holes specified in Table 65 on page 162.
2. On the back of each rack rail, partially insert a mounting screw into the lowest hole
specified in Table 65 on page 162.
3. Install the mounting shelf on the back of the rack rails. Rest the bottom slot of each
flange on a mounting screw.
4. Partially insert the remaining screws into the open holes in each flange of the mounting
shelf (see Figure 45 on page 163 and Figure 46 on page 164).
5. Tighten all the screws completely.
