Replacing a CFEB

One or two CFEBs can install into the uppermost slots in the rear of the chassis, as
shown in
in reset mode. CFEBs are hot-pluggable, as described in
(FRUs)"
If the active CFEB fails or is removed from the chassis, the effect depends on whether
two CFEBs are installed:
In both cases, all components in the Packet Forwarding Engine reset, and it takes
approximately one minute for the new CFEB to become active; synchronizing router
configuration information can take additional time, depending on the complexity of
the configuration.
To replace a CFEB, perform the following procedures:

Figure 2 . Only one CFEB is active at a time, with the optional second CFEB
on page 3. Removing the standby CFEB has no effect on router function.
If there is only one CFEB, forwarding halts until the CFEB is replaced and
functioning again.
If there are two CFEBs, forwarding halts until the standby CFEB boots and
becomes active.

Installing a CFEB
Place an electrostatic bag or antistatic mat on a flat, stable surface.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis. Make sure the router
is attached to a proper earth ground. For more information about ESD, see
"Preventing Electrostatic Discharge Damage"
If you are removing the active CFEB, press and hold the offline button on the
