Tools and Equipment
The following section lists tools and equipment for unpacking, performing
maintenance, and setting up your Cisco XR 12406 router.
• ESD-preventive strap
• 3/16-inch flat-blade screwdrivers
• 1/4-inch flat-blade screwdrivers
• 9/15-inch (14-mm) wrench
• 3/4-inch (19-mm) socket and ratchet wrench

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.
