Removing an MX240 MPC
When you remove an MPC, the router continues to function, although the MIC interfaces
installed on the MPC being removed no longer function.
An MPC installs horizontally in the front of the router. The MPCs are hot-insertable and
hot-removable. A fully configured MPC can weigh up to 18.35 lb (8.3 kg). Be prepared to
accept its full weight.
To remove an MPC (see Figure 140 on page 313):
1. Have ready a replacement MPC or DPC blank panel and an antistatic mat for the MPC.
Also have ready rubber safety caps for each MIC using an optical interface on the MPC
that you are removing.
2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
