Chassis slot number 17: upper right-most line card slot. The 10 Gigabit Ethernet Line Card (XGLC)
is a full-height line card that takes up the upper and lower slots in the back of the chassis. Use the
upper slot number only when referring to installed XGLCs. Slot numbering for other half-height
lines cards is maintained: 17 to 32 and 33 to 48, regardless of the number of installed XGLCs.

The following subsections describe each bus.
320 Gbps Switch Fabric
The System Management Card (SMC) is an IP-based (packetized) switch fabric that provides a transport path
for user data throughout the system. Its 320 Gbps switch fabric establishes inter-card communication between
the SMCs and other application cards within the chassis along with their associated line cards.
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 (GigE) switching hierarchy from
both SMCs to each of the 14 application card slots in the chassis. Each application card is provisioned with
a GigE 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 with 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, data path errors, redundant/secondary path switchovers,
card resets and failovers). Additionally, the System Management Bus monitors and controls the fan trays,
PFUs, and alarming functions.
