After the reboot, the router recognizes the new CFEB or CFEB-E.

PICs are housed in the front of the router, as shown in Figure 1 on page 6. PICs are
hot-insertable and hot-removable, as described in "M7I Field-Replaceable Units (FRUs)"
on page 85. Removing a PIC does not affect router function, except that the PIC no longer
receives or transmits data.
To replace a PIC, perform the following procedures:

WARNING: Do not look directly into transceivers or into the ends of fiber-optic
cables connected to a transceiver. Fiber-optic transceivers emit laser light
that can damage your eyes.
CAUTION: When handling fiber-optic transceivers and fiber-optic cable,
observe the following precautions:
Do not leave a fiber-optic transceiver uncovered except when inserting or
removing cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
Do not bend fiber-optic cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
Do not let fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening
point.
