power source. You must provide input, return, and earthing (grounding) wiring at the site, and install and
protect the wiring in accordance with local and national wiring regulations. The Cisco uBR10012 router
DC-input terminal block accepts a minimum of 6 AWG wire. An insulation rating of 167° Fahrenheit
(75° Celsius) is required for the 6 AWG wire for 3000 W of power.

Cabling Guidelines

When planning the location of a new system, consider the signal type, signal speed, and transmission
medium. Also, consider the distance limitations for signaling, EMI, and connector compatibility. The
distance and rate limits shown in
