Installing A Mounting Shelf In A Rack Or Cabinet For An Ex9214 Switch - Juniper EX9214 Hardware Manual

Installing a Mounting Shelf in a Rack or Cabinet for an EX9214 Switch

The EX9214 switch can be installed in a four-post rack or cabinet or in an open-frame rack. You must
install the mounting shelf, which is included in the shipping container, on the rack before installing the
switch because the weight of a fully loaded chassis can be up to 350 lb (158.8 kg).
Table 57 on page 155 specifies the holes in which you insert cage nuts and screws to install the
mounting shelf 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.
