PTX5000 DC Power Distribution

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 PTX5000. A
pair of cables (one input and one return) connects each set of terminal studs to the power distribution
panel.
NOTE: All inputs on the DC PDU in slot 0 must be powered by dedicated power feeds derived
from feed B, and all inputs on the DC PDU in slot 1 must be powered by dedicated power feeds
derived from feed A. This configuration provides the commonly deployed A/B feed redundancy
for the system.
