Guidelines for a Standalone Equipment Shelf or Tabletop
Installation
The chassis should already be in the area where you want to install it. If you have not determined where to
install your chassis, see the
Preparing Your Site for Installation
section for information about site
considerations.
When installing the Cisco Catalyst 9800-40 Wireless Controller on a sturdy equipment shelf or tabletop,
ensure that the surface is clean and that you have considered the following:
• The Cisco Catalyst 9800-40 Wireless Controller requires at least 3 inches (7.62 cm) of clearance at the
inlet and exhaust vents (the front and rear sides of the chassis).
• The chassis should be installed off the floor. Dust that accumulates on the floor is drawn into the interior
of the controller by the cooling fans. Excessive dust inside the controller can cause over temperature
conditions and component failures.
• There must be approximately 19 inches (48.3 cm) of clearance at the front and rear of the chassis to
install and replace FRUs, or to access network cables and equipment.
• The chassis needs adequate ventilation. Do not install it in an enclosed cabinet where ventilation is
inadequate.
• Keep the cable-management bracket ready, if you plan to install it on the front of the chassis.
• Ensure that an adequate chassis ground (earth) connection exists for your controller chassis (see the
Attaching a Chassis Ground Connection
section).
Installing the Controller on a Standalone Equipment Shelf or
Tabletop
Step 1
Remove any debris and dust from the tabletop or platform, as well as the surrounding area.
Step 2
Lift the chassis into position on the equipment shelf or tabletop.
Step 3
to
Step 9
are optional, if you are installing the Cisco Catalyst 9800-40 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.
