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.
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.
