Grounding The Chassis - Cisco UC520-24U-8FXO-K9 Overview

Be sure to leave space above and below each unit in a rack to allow for cooling air circulation.
Note
If you are deploying a single integrated wireless access point, connect the antenna to the front
Tip
panel before you mount the unit on a wall. It is difficult to attach an antenna after the
platform is mounted to a wall.
Use two screws for each side (supplied with the rack) to attach the unit to the rack-mount
Step 1
brackets, then attach power supply with rack-mount bracket to a 19" rack.
Step 2 Start the lower pair of screws first, resting the brackets on the lower screws while you insert
the upper pair of screws.
The screw slots in the brackets are spaced to line up with every second pair of screw holes in
Tip
the rack. When the correct screw holes are used, the small threaded holes in the brackets line
up with unused screw holes in the rack. If the small holes do not line up with the rack holes,
you must raise or lower the brackets to the next rack hole.

Grounding the Chassis

Warning This equipment must be grounded. Never defeat the ground conductor or operate the
equipment in the absence of a suitably installed ground conductor. Contact the
appropriate electrical inspection authority or an electrician if you are uncertain that
suitable grounding is available. Statement 1024
You must connect the chassis to a reliable earth ground; the ground wire must be installed in
accordance with local electrical safety standards.
• For NEC-compliant grounding, use size 14 AWG (2 mm) or larger copper wire and an appropriate
user-supplied ring terminal with an inner diameter of 1/4 inch (5 to 7 mm).
The UC 520 is not NEBS-compliant.
