FIGURE2-3 SupportRail and Fixings (19-inch Rack)
The mounting screws should be placed in position pairs E1 and F1, E2 and F2, E3
and F3, E4 and F4 or E5 and F5. The pair of holes to be used depends on the front-
to-back depth of the rack (mounting flange to mounting flange). The holes marked
with the appropriate figure, as shown in TABLE2-2, should be closest to the rear of
the chassis.
The slots labeled G are used for mounting the rear flanges(see FIGURE2-6 on
page17). Only one of the vertical pairs of holes in the rear flanges should be used.
The spacers must be placed with the flat side towards the chassis and the
countersink towards the support rail (see FIGURE2-4).
