DC Power, Connection, and Power Cable Specifications

Each DC power supply has a single DC input (–48 VDC and return) that requires a
dedicated 15 A (–48 VDC) circuit breaker. If the J6350 router contains redundant
DC power supplies, one power supply must be powered by a dedicated power

a dedicated power feed derived from feed
commonly deployed
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.
