Module Descriptions
The following modules are available for the
SmartSwitch 9000 Series:
ATM Access Modules
An ATM Access module is a device that is capable
of providing connectivity between FDDI or ATM
networks and the INB and the FNB or both. The
ATM Access Module 9A128_01 connects an
external ATM network to one of the two FDDI
networks on the Flexible Network Bus (FNB)
backplane. The ATM Access Module 9A426_02
connects two external ATM networks to either the
Internal Network Bus (INB) backplane, the FNB
backplane or both. The ATM Access Module
9A426_01 connects one external ATM network to
either the INB backplane or the FNB backplane.
Ethernet MicroLAN Switch Modules
The Ethernet MicroLAN Switch Module is a four
channel Ethernet to FDDI bridge. Up to three
front panel Ethernet networks can be connected
to this module. These networks can be bridged to
any other Ethernet or FDDI segment, and to any
other MMAC-Plus card via the FNB bus. The
Ethernet MicroLAN device is equipped with an
advanced Intel i960 microprocessor. This
microprocessor provides a platform for all
management functions within a scalable RISC-
based architecture. Three 50-pin front panel
ports provide 12 individual Ethernet connections
each. All ports function as repeaters for incoming
data which retime and retransmit all packets.
Bridging between the front panel channels and/or
to any other module in the chassis is done via
FDDI ring 1 or FDDI ring 2 of the FNB bus. The
following devices are the Ethernet MicroLAN
