Chapter5 Maintaining the Router
Removing and Replacing an RP or a Line Card
Step1 If the Input OK and Output OK LEDs are off, make sure that the:
•PEM is firmly seated in the bay and the captive screws are tightened securely.
•DC power source circuit breakers are switched on.
•DC power cables are securely attached to the PDU terminal block.
•Power switch is set to the on (1) position.
Step2 If the amber MISWIRE LED is on, the wires on the power block are reversed.
a. Power off the PEMs and make sure the DC power source circuit breakers are
switched off. Go to Step9 of the installation procedure and reconnect the
wires correctly to each of the power connector blocks.
b. Switch on the DC source power circuit breakers and power on the PEMs.
If the problem still exists, replace the PEM.
If replacing the PEM does not correct the problem, contact a Cisco service
representative for assistance.
Removing and Replacing an RP or a Line Card
Line cards can occupy any slot, 0 (the top slot) through 4, in the RP and line ca rd
cage (Figure 5-27). The Cisco XR 12406 router is configured with the RP in slot 5
(the bottom slot). A redundant RP can be installed in any slot, but requires a l ine
card spacer to comply with EMI emission standards.
Cisco XR 12406 router line cards support OIR, so they can be rem oved and
installed while the router remains powered up. RPs also support O IR, but are
hot-swappable only when the system is equipped with two RPs.
Caution If you are removing, but not replacing a card in the chassis, you must have a blank
filler in place for EMI shielding and to ensure proper cooling.
Additional line card information can be found in the installation and configuration
documentation for each type of line card.
