The Backplane

The 9C106 SmartSwitch 9000-6 Slot chassis provides six distinct backplane buses,

and the 9C706 provides an additional seventh bus, the Cell Transfer Matrix. Each

bus serves a particular set of needs. The seven backplane buses are shown in

Figure 1-1.

The descriptions of the seven backplane buses are as follows:

System Management Bus 1

The System Management Bus 1, abbreviated SMB-1, is a management bus

devoted solely to transferring management information between the modules in

the chassis. It is through the SMB-1 that modules inform each other, and the

System Monitor, of their current operating status, diagnostic test results,

initialization queries and other information. The SMB-1 operates at 1 Mbps, and

every module in the chassis has a connection to it.
