Assembling the rack hardware
Procedure
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 7) or retainer nuts (9 in Figure 7) 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.
