Electrical Circuit Requirements
Each Cisco RFGW-10 UEQAM requires a dedicated electrical circuit. If you equip it with dual power
feeds, provide a separate circuit for each DC PEM to avoid compromising the power redundancy feature.
The Cisco RFGW-10 UEQAM can be powered by a DC source. Ensure that the equipment grounding is
present and observe power strip ratings. Make sure that the total ampere rating of all products plugged
into the power strip does not exceed 80% of the rating.

Site Cabling Guidelines
This section contains guidelines for wiring and cabling at your site. When preparing your site for
network connections to the Cisco RFGW-10 UEQAM, 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, or
unshielded twisted-pair cabling.
Also consider any additional interface equipment you need, such as transceivers, hubs, switches,
modems, channel service units (CSU), or data service units (DSU).
Before you install the Cisco RFGW-10 UEQAM, have all additional external equipment and cables on
hand. For ordering information, contact a customer service representative.
The extent of your network and the distances between network interface connections depend in part on
the following factors:
•
•
•
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 a guideline in planning your
network connections prior to installing the Cisco RFGW-10 UEQAM.
