Installing an MX240 MIC
To install a MIC (see Figure 96 on page 242):
1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2. If you have used a dual-wide MIC and are now replacing it with two “single” MICs,
install the septum (see Figure 95 on page 241):
a. Place the MPC on a flat surface (if necessary, remove the MPC from the router as
described in “Removing an MX240 MPC” on page 311).
b. Position the septum in the center of the MPC so that it lines up with holes labeled
S on the top of the MPC.
c. Insert a screw into each of the two holes labeled S, and then tighten completely.
d. On the bottom of the MPC, insert a screw into each of the four holes labeled S, and
then tighten completely.
e. Install the MPC as described in “Installing an MX240 MPC” on page 243.

on the faceplate. Install a cap if necessary.
