32 Gbps Control Bus
The Control Bus features redundant 32 Gbps Ethernet paths that interconnect all control and management processors
within the system. The bus uses a full-duplex Gigabit Ethernet (GE) switching hierarchy from both SMCs to each of the
14 application card slots in the chassis. Each application card is provisioned with a GE switch to meet its specific needs.
This bus also interconnects the two SMC modules.

System Management Bus
The System Management Bus supports management access to each component within the chassis. It provides a
communication path from each SMC to every card in the system supporting a 1 Mbps transfer rate to each card. This
allows the SMCs to manage several low-level system functions, such as supplying power, monitoring temperature,
board status, pending card removals, and data path errors, and controlling redundant/secondary path switchovers, card
resets, and other failover features. Additionally, the System Management Bus monitors and controls the fan trays, power
filter units, and alarming functions.

280 Gbps Redundancy Bus
The Redundancy Bus consists of multiple, full-duplex serial links providing packet processing card-to-line card
redundancy through the chassis‘ Redundancy Crossbar Cards (RCCs) as shown below.
