Operation
The 9E106-06 module is a seven port device, six front panel ports, each
representing a separate Ethernet collision domain, and one backplane connection
to FNB-1 or FNB-2.
As shown in Figure 3-1, packets received through one of the six front panel
Ethernet ports and destined for another SmartSwitch 9000 module are translated
by the i960
Switch Processor into a FDDI frame format and then sent to FNB-1 or
FNB-2.
