One FPC can be installed horizontally in the front of the router. The FPCs are hot-insertable and hot-removable. A fully configured FPC can weigh up to 18 lb (8.2 kg).
Place the MPC on a flat surface (if necessary, remove the MPC from the router as described in “Removing an MX240 MPC” on page 293). Position the septum in the center of the MPC so that it lines up with holes labeled on the top of the MPC.
MX240 3D Universal Edge Router Hardware Guide If the MIC uses fiber-optic cable, remove the rubber safety cap from each transceiver and the end of each cable. WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.
