Step 3
to
Step 9
are optional, if you are installing the Cisco Catalyst 9800-80 Wireless Controller on a rack
shelf. The chassis rack-mount brackets must be installed prior to installing the cable-management brackets.
See the
Attaching the Front Rack-Mount Brackets
section.
Note
Step 3
Attach the front rack-mount brackets. Locate the threaded holes in the front sides of the chassis (first holes beyond the
vent holes) and use the package of black screws that is shipped with the chassis.
Step 4
Align the front rack-mount bracket to one side of the chassis.
Step 5
Insert and tighten the screws on one side.
Step 6
Repeat
Step 3
to
Step 5
on the other side of the chassis. Use all the screws to secure the rack-mount brackets to the
chassis.
Step 7
Gather the two cable-management brackets and screws shipped with your chassis. See the
Attaching Cable Management
Bracket
section.
Step 8
Screw a cable-management bracket to each side of the rack-mount brackets that are attached to the chassis. Use two
screws for each cable-management bracket. Use a screw from the package of four screws.
Ensure that the cable-management U feature device has the open end pointing outwards when you attach it to
the chassis.
Note
Step 9
Check that all the screws are securely tightened.

Guidelines for Rack Installation
The Cisco Catalyst 9800-80 Wireless Controller can be installed in the following rack types:
• Two-post rack, either 19 inch or 23 inch. Inner clearance (the width between the inner sides of the two
posts or rails) must be at least 19 inches (48.26 cm). Airflow through the chassis is from front to back.
• Four-post, 19-inch equipment rack. Inner clearance (the width between the inner sides of the two posts
or rails) must be at least 19 inches (48.26 cm). Airflow through the chassis is from front to back.
The Cisco Catalyst 9800-80 Wireless Controller can be installed with front rack-mount brackets.
When planning your rack installation, consider the following guidelines:
• The Cisco Catalyst 9800-80 Wireless Controller requires a minimum of 1.75 inches or 4.45 cm rack units
of vertical rack space. Measure the proposed rack location before mounting the chassis in the rack.
• Before using a particular rack, check for obstructions (such as a power strip) that could impair the
rack-mount installation. If a power strip does impair a rack-mount installation, remove the power strip
before installing the chassis, and then replace it after the chassis is installed.
• Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it back
near a wall or cabinet for normal operation and pull it out for maintenance (installing or moving cards,
connecting cables, or replacing or upgrading components). Otherwise, allow 19 inches (48.3 cm) of
clearance to remove field-replaceable units.
