T320 Router SIBs
Three SIBs are installed in the router. The SIBs are located at the center rear of the chassis
in the slots labeled SIB0 through SIB2. (See “T320 Router SIBs” on page 652.)
Each FPC has a dedicated ASIC with five high-speed links that connect to the SIBs. Two
high-speed links connect to SIB1 and SIB2. One high-speed link connects to SIB0. SIB0
acts as a backup to SIB1 and SIB2. In the event of a complete SIB failure, SIB0 will become
active. Because SIB0 has only one high-speed link to each FPC, only three links will remain
active. A slight degradation in forwarding capacity may occur. When the failed SIB is
replaced, it will become active and SIB0 will revert to backup. The router will regain full
forwarding capacity.
T640 Router, T1600 Router, and TX Matrix Router SIBs
Five SIBs are installed in the router. The SIBs are located at the center rear of the chassis
in the slots labeled SIB0 through SIB4 (top to bottom). (See “T640 Router, T1600 Router,
and TX Matrix Router SIBs” on page 652.)
Each FPC1 and FPC2 has a dedicated ASIC with five high-speed links that connect to the
SIBs (one link per SIB). An FPC3 has two dedicated ASICs, and each ASIC has five
high-speed links that connect to the SIBs (a total of 10 links). One of the five SIBs—usually
SIB0—acts as a backup to the remaining four SIBs. In the event of a SIB failure, the backup
SIB becomes active and traffic forwarding continues without any degradation. When the
failed SIB is replaced, it becomes the new backup.
The SIBs are hot-insertable and hot-removable.
