Installing the M7i CFEB and CFEB-E

To install the CFEB or CFEB-E (see Figure 34 on page 92):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect

the strap to one of the ESD points on the chassis.

2. Verify that the ends of the ejector handles are pulled outward to a position nearly

perpendicular to the faceplate of the CFEB or CFEB-E.

3. Place one hand under the CFEB or CFEB-E to support it and grasp one of the ejector

handles at the front with the other hand.

4. Align the rear of the CFEB or CFEB-E with the guides inside the chassis and slide it in

completely.

5. Press the ejector handle at each end of the CFEB or CFEB-E inward.

6. Tighten the thumbscrew on each ejector locking tab (shown in Figure 4 on page 10)

to seat the CFEB or CFEB-E firmly in the chassis.

7. Press and hold the ONLINE/OFFLINE button on the CFEB or CFEB-E faceplate until

the green OK LED lights steadily.

You can verify correct CFEB or CFEB-E functioning by issuing the show chassis cfeb

command described in “Maintaining the M7i CFEB and CFEB-E” on page 73.

Upgrading and Downgrading the CFEB and CFEB-E

To upgrade by replacing a CFEB with a CFEB-E or to downgrade by replacing a CFEB-E

with a CFEB requires a system reboot after swapping the CFEB devices.

To upgrade from a CFEB to a CFEB-E or downgrade from a CFEB-E to a CFEB:

1. Remove the CFEB or CFEB-E as described in “Removing the M7i CFEB and CFEB-E”

on page 91.

2. Install the upgrade CFEB-E or downgrade CFEB as described in “Installing the M7i

CFEB and CFEB-E” on page 92.

3. Reboot the router by issuing the following CLI command:

user@host> request system reboot

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