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 CW9800H1 and CW9800H2 Wireless Controllerss, 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).
Before you install the controller, have all the additional external equipment and cables at hand. For ordering
information, contact a Cisco customer service representative.
The extent of your network and the distances between network interface connections depend in part on the
following factors:
• Signal type
• Signal speed
• Transmission medium
The distance and rate limits referenced in the following sections are the IEEE-recommended maximum speeds
and distances for signaling purposes. Use this information as guidelines when planning your network
connections prior to installing the Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllerss.
If wires exceed recommended distances, or if wires pass between buildings, give special consideration to the
effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy
phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you
have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and
shielding.
