SIBs create the switch fabric for the T4000 Core Router. Each T4000 router contains
five SIBs, located at the center rear of the chassis in the slots labeled
(top to bottom). One of the five SIBs acts as a backup to the remaining four SIBs. If a SIB
fails, the backup SIB becomes active, and traffic forwarding continues without any
degradation. When the failed SIB is replaced, it becomes the new backup. SIBs are
hot-insertable and hot-removable.
The T4000 router supports the SIB listed in
