This product requires short-circuit (overcurrent) protection to be provided as part of the building installation.
Install only in accordance with national and local wiring regulations.
Caution
The Cisco Catalyst 9800-80 Wireless Controller installation must comply with all applicable codes and is
approved for use with copper conductors only. The ground bond fastening hardware should be of compatible
material and preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material.
Attachment of the chassis ground to a central office or other interior ground system must be made with an
AWG #6 gauge wire, copper ground conductor at a minimum.
Note
Electrical Circuit Requirements
The Cisco Catalyst 9800-80 Wireless Controller requires a dedicated electrical circuit. If you equip it with
dual-power feeds, you must provide a separate circuit for each power supply to avoid compromising the power
redundancy feature.
The Cisco Catalyst 9800-80 Wireless Controller can only be powered by an AC source. Ensure that equipment
grounding is present and observe power-strip ratings. Make sure that the total ampere rating of all the products
plugged into the power strip does not exceed 80 percent of the rating.
The Cisco Catalyst 9800-80 Wireless Controller can support two AC power supplies. The AC power supply
requires a 20 A circuit breaker.

Site Cabling Guidelines
This section contains guidelines for wiring and cabling at your site. When preparing your site for network
connections to the Cisco Catalyst 9800-80 Wireless Controller, consider the type of cable required for each
component, and the cable limitations. Consider the distance limitations for signaling, EMI, and connector
compatibility. Possible cable types are fiber, thick or thin coaxial, foil twisted-pair cabling, or unshielded
twisted-pair cabling.
Also consider any additional interface equipment you need, such as transceivers, hubs, switches, modems,
channel service units (CSUs), or data service units (DSUs).
