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.
