Electrical Circuit Requirements
Each Cisco ASR 907 Router requires a dedicated electrical circuit. If you equip it with dual power feeds,
provide a separate circuit for each power supply to avoid compromising the power redundancy feature.
The Cisco ASR 907 Routers can be powered by a DC source or an AC source. Ensure that equipment grounding
is present and observe the 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 ASR 907 Router, consider the type of cable required for each component, and the
cable limitations. Consider the distance limitations for signaling, electromagnetic interference (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 begin, read these important notes about cabling:
• The T1/E1 interface module for the Cisco ASR 907 Router uses a high-density connector that requires
• Shielded cables must be used to connect to the RJ-45 alarm connector on the fan tray in order to comply
Before you install the Cisco ASR 907 Router, have all the additional external equipment and cables on hand.
For information about ordering, contact a Cisco customer service representative.
The extent of your network and the distances between the network interface connections depend in part on
the following factors:
