Most Cisco 12016, Cisco 12416, and Cisco 12816 Router field-replaceable units
(FRUs) can be removed and replaced with the power on and the system operating.
This is known as online insertion and removal (OIR). Power supplies, line cards,
the RP, CSCs, SFCs, and alarm cards all support OIR. Unless otherwise noted, the
maintenance tasks described in this chapter can be performed while the router
remains powered on.
In some cases it may be necessary to power off the router, for example, to upgrade
power supplies or to replace a power shelf. Use the following procedure to power
off the router.
Set the power switch on each power supply to the off (0) position.
Power off all circuit breakers for the source power lines connected to the power
supplies.
