Most Cisco XR 12410 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
both power supplies and PDUs. 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.
Verify that the Pwr OK indicator on each power supply is off.
Verify that the OK indicator on the blower module is off.
