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.

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 9F241-12 module has a dual

attachment to the FNB backplane, connecting to both FNB-1 and FNB-2. The

module can insert into the FNB or bypass it. 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 an FDDI

collapsed backbone.

The i960 core provides the SNMP protocol stacks, as well as support for 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 also

provided by the i960 core.
