TR MicroLAN Switch Modules
The 9T122-08 and 9T122-24 TR MicroLAN Switch
Modules provide connectivity to two Token Ring
networks through the Fiber Distributed Data
Interface (FDDI) backplane in the chassis. The TR
MicroLAN Switch Module’s single 24-port Token
Ring, or two 12-port Token Rings use standard
RJ-45 connectors supporting either Unshielded
Twisted Pair (UTP) or Shielded Twisted Pair (STP)
lobe wiring. The rings interconnect across the
chassis’s Flexible Network Bus (FNB), a dual 100
Mbps FDDI backplane, and can be configured for
FNB-1 or FNB-2.
The 9T125-08 and 9T125-24 TR MicroLAN Switch
Modules provide connectivity to two Token Ring
networks. The rings interconnect across the
chassis’s Flexible Network Bus (FNB), a dual 100
Mbps FDDI backplane, and can be configured for
FNB-1 or FNB-2.
Token Ring SmartSwitch Module
Designed specifically for collapsed Token Ring
backbones, the 9T425-16 Token Ring
SmartSwitch occupies two slots in the chassis. It
is equipped with 16 copper RJ-45 dedicated
Token Ring (DTR) lobe/station ports, also known
as concentrator or C-ports. The module is
considered a “hard card,” with all switching
functions performed by the Fast Packet Switch
(FPS Application Specific Integrated Circuits
ASICs). The Token Ring SmartSwitch Module
attaches to the Internal Network Bus (INB) 2
backplane and has System Management Bus -1
(SMB-1) and SMB-10 connections for system
management.
