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.
