Choosing a Physical Location for the Cisco 8500 Series Wireless Controller
Power Requirements
Installation of this equipment must comply with local and regional electrical regulations governing the
installation of information technology equipment by licensed electricians. This equipment is designed
to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA 75,
1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power
ratings on options, refer to the product rating label or the user documentation supplied with that option.
Caution Protect the controller from power fluctuations and temporary interruptions with a regulating
uninterruptible power supply (UPS). This device protects the hardware from damage caused by power
surges and voltage spikes and keeps the system in operation during a power failure.
When installing more than one controller, you may need to use additional power distribution devices
(PDUs) to safely provide power to all devices. Observe the following guidelines:
• Balance the controller power load among available AC supply branch circuits.
• If you are using the AC version [AIR-CT8510-K9], do not allow the overall system AC current load
to exceed 80 percent of the branch circuit AC current rating.
• Do not use common power outlet strips for this equipment.
• Provide a separate electrical circuit for the controller.
Please follow the instructions in Connecting the DC Version of the 8500 [AIR-CT85DC-K9] to a Power
Source, page 1-41 to connect the DC version [AIR-CT85DC-K9] to DC power source.
