Description
1
Slot number 1 (left-most application card slot)
2
Chassis midplane: provides intra-chassis communications and data transport paths between the various installed cards
3
SPIO cross-connect bus
4
Chassis slot number 16: right-most application card slot
5
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.

320 Gbps Switch Fabric
System Management Card (SMC), this IP-based, or packetized, switch fabric provides a transport path for user data
throughout the system. The 320 Gbps switch fabric establishes inter-card communication between the SMC(s) and other
application cards within the chassis, and their respective line cards.
