NOTE: Power cords and cables must not block access to router components or drape
where people could trip on them.
For information about the AC power supply, including electrical specifications and
a description of components, see “AC Power Supply” on page 20. For instructions on
connecting the power cord and grounding cable during initial installation, see
“Connecting Power to an AC-Powered Router” on page 62. For instructions on replacing
the AC power cord, see “Disconnecting and Connecting AC Power” on page 110.
DC Power, Connection, and Cable Specifications
The DC power supplies in slots P/S 0 and P/S 1 must be powered by dedicated
power feeds derived from feed A, and the DC power supplies in slots P/S 2 and P/S
3 must be powered by dedicated power feeds derived from feed B. This configuration
provides the commonly deployed A/B feed redundancy for the system. 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 the field-wiring
terminals to the power distribution panel.
