Powering Off the Router

Unless otherwise noted, the maintenance tasks described in this chapter can be performed while the router remains powered on. Most Cisco XR 12406 router field replaceable units (FRUs) support online insertion and removal (OIR), which means they can be removed and installed (hot-swapped) while the router remains powered on.

•Line cards, switch fabric cards (SFCs), alarm cards, and the blower module are hot-swappable.

•Power modules, clock and scheduler cards (CSCs), and RPs also support OIR, but are hot-swappable only when the system is equipped with two power modules, two CSCs, or two RPs, respectively.

•AC and DC power distribution units (PDU) do not support OIR.

Use the following procedure to power off an AC- or a DC-powered router.
