When you remove an MPC, the router continues to function, although the interfaces that are installed on
the MPC that is being removed no longer function.
An MPC is installed horizontally in the front of the router. MPCs are hot-insertable and hot-removable. A
fully configured MPC can weigh up to 31.57 lb. (14.32 kg). Be prepared to accept the full weight of the
MPC as you slide the MPC out of the chassis.
Ensure that you have the following parts and tools available to remove an MPC:
•
ESD grounding strap
•
An electrostatic bag or an antistatic mat
•
Have ready a replacement MPC cover and an antistatic mat for the MPC.
NOTE: Placing a line card in an electrostatic bag might require a second person to assist with
sliding the line card into the bag.
To remove an MPC (see Figure 109 on page 225):
1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on
the chassis.
2. Label the cables connected to each port on the MPC so that you can reconnect the cables to the correct
ports later.
3. Use one of the following methods to take the MPC offline:
•
Press and hold the offline button on the MPC. The green OK/FAIL LED next to the button begins
to blink. Hold the button down until the LED goes off.
•
Issue the following CLI command:
user@host>request chassis fpc slot slot-number offline
For more information about the CLI command, see the CLI Explorer.
4. Disconnect the cables from the ports that are installed in the MPC.
WARNING: Do not look directly into a fiber-optic transceiver or into the ends of
fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to a
transceiver emit laser light that can damage your eyes.
