Operation
DC/DC Converter
The DC/DC converter converts the 48 VDC on the system power bus to the 
necessary operating voltages for its host network services module. The diagnostic 
controller monitors and controls the operation of the DC/DC converter.
FNB Interface
SmartSwitch 9000 modules are designed with one of two attachment policies. One 
allows dual attachment of a module to either FNB-1 or FNB-2; the second allows 
dual attachment to both FNB-1 and FNB-2. The 9E106-06 has one dual attachment 
to the FNB backplane, connecting to either FNB-1 or FNB-2. The module can 
insert into either the FNB-1 or FNB-2, or bypass both. These flexible configuration 
options make the SmartSwitch 9000 ideal for networks designed to Bridge/Route 
multiple lower speed LANs to FDDI and/or networks designed using a FDDI 
collapsed backbone.
i960 Switch
The i960 Switch Processor is the first of the dual i960 RISC microprocessors built 
into the 9E106-06 Module. This processor provides the packet forwarding logic 
and can be configured to run as a layer two bridge, or as a SecureFast switch.
i960 Host
The i960 Host Processor is the second of the dual i960 RISC microprocessors built 
into the 9E106-06 Module. This processor provides the SNMP protocol stacks to 
support industry standard MIBs. Additionally, Cabletron enterprise extension 
MIBs are supported for each media type. Advanced management services, such 
as the Distributed LAN Monitor, telnet and network address to MAC address 
mapping, are provided by this i960 processor.
