do not mount multiple chassis side by side. If you do, one chassis draws in
warm air from the other, limiting the effectiveness of the cooling fans.
1 Install the brackets at the back of the chassis, as shown in Figure 27 .

2 Use the dimensions shown in Figure 28 to mark the locations where you
will drill the pilot holes into the mounting surface.
Figure 28 Chassis Wall-mount Dimensions
CAUTION: If you wall-mount the NBX 100 chassis, you must attach the
chassis securely to a plywood mounting board which is firmly attached to
the wall. A fully configured 6-slot chassis can weigh up to 13.5 kg (30 lb).
3 Drill pilot holes at the locations you marked.
4 Install the two lower mounting screws.
Do not tighten the screws. Thread them just far enough so that they will
support the weight of the NBX 100 chassis.
