Assembling the rack hardware
1. Determine how the device can be oriented in the rack so that the nonport side has access to intake air (cool).
2. Install clip nuts or retainer nuts (as shown in the previous figure) in rack rail locations shown in the following figure.
These nuts will secure the 10-32 screws that mount the Port Side Exhaust Kit shelf and 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.
