Installing the flush mount Intake Air Duct kit
Use the following procedure to install the flush mount Intake Air Duct kit.

After you unpack the kit, check the contents required for this installation against the parts list in
Figure 15 on page 42. This
hardware kit is a universal kit, and not all hardware is used for this installation.
Installing the rack hardware
1. Determine how the device can be oriented in the equipment rack so that the port side has access to intake (cool) air.
NOTE
Be sure to allow for an additional 1U rack space above where you will install the top intake assembly to provide
clearance for raising the intake and inserting it on to side duct tabs. Refer to
Step 6 .
2. Install either clip nuts or retainer nuts depending on whether your rack has round holes or square holes. These allows you to
secure the device to the rack posts.
NOTE
For posts with round holes, use the clip nuts on the rack uprights for securing M6 x 1.0 x 12 screws. For posts with
square holes, use the retainer nuts. Refer to the following figure.
