ATTENTION
This hardware kit is a universal kit, and some hardware will not be used in this installation.
Torque requirements
Use the following torque settings when tightening screws that secure the rack mount kit and Intake Air Duct Kit to
the equipment rack.
Install the rack hardware
1. Determine how the switch 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 5b.
2. Install either clip nuts or retainer nuts depending on whether your rack has round holes or square holes.
These will allow you to secure the switch 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
Figure 2 .
