HAPTER NSTALLING THE
WARNING: To maintain proper cooling in the chassis
and to maintain safety compliance, make certain that
blank faceplates cover any empty slots.
If you install more than one chassis in a rack, install
the bottom chassis first. Make certain that there is
sufficient space between the bottom chassis and
the top chassis.
If you install the chassis in a Metric rack slot, install
the rack-mount clips and screws in the closed slots
of the rack-mount flanges. If you install the chassis
in Telco rack slots, position the chassis and then
install the screws and rack-mount clips in the open
slots.
Figure 17 shows the Telco and Metric slots and the
location of the preinstalled rack-mount flange on a
Switch 4007 chassis.
