IG550 Integrated Gateway
Issue 5.1 June 2006 143
Most sites distribute DC power through a main conduit that leads to frame-mounted DC power
distribution panels, one of which might be located at the top of the rack that houses the router. A
pair of cables (one input and one return) connects each set of terminal studs to the power
distribution panel.
Each DC power cable (ñ48 VDC and return) must be 14 AWG single-strand wire cable, or as
permitted by the local code. Each lug attached to the power cables must be a ring-type,
vinyl-insulated TV14-6R lug, or equivalent.
