TABLE 8 Torque requirements for mounting screws
Screw size Torque
6-32 x .25 in. (.635 cm) Phillips screw 8.75 in-lb (10 cm-kg)

Assembling the rack hardware
1. Determine how the device can be oriented in the rack so that the non-port side has access to intake air (cool).
2. Install clip nuts (8 in
Figure 3 on page 33) or retainer nuts (9 in Figure 3 on page 33) in rack rail locations shown in the following
figure. These nuts will secure the 10-32 screws that mount the rack kit's shelf and the device to the rack. For rails with round
holes, use clip nuts. For rails with square holes, use retainer nuts. Note that the following figure shows relative positions for these
nuts in the rack rails to mount the shelf and device. You may mount the shelf and device in 9U of rack space higher or lower in
the rack than shown.
