FDDI and Token Ring Modules - The EMME recognizes the following
FDDI and Token Ring modules, but the EMME management does not
provide control or statistics.
• CRM-3T
• SNACMIM
• TRMIM-32A
• TRMIM-34A
• TRRMIM-F2T
• TRRMIM-F3T
With TRMMIM version 2.02 or greater, both Token Ring and Ethernet
modules can reside in the same chassis and support physical management
capabilities of the Token Ring MIMs using the TRMMIM as the token
ring management module. Without the TRMMIM, the EMME will only
recognize the Token Ring modules.
Ethernet Channel D - Ethernet channel D is provided by one of the two
redundant AUI ports on the front panel of the EMME. With the correct
transceiver, the AUI ports provide the capability for cable redundancy and
a variety of Ethernet transmission media connections, including twisted
pair, fiber optic, and thick or thin Ethernet coaxial cable.
Either one of the AUI ports can act as the bridge port to the external
network. When the EMME is first powered up, the AUI 1 port acts as the
bridge port and the AUI 2 port is off. Using the EMME's network
management capabilities, you can reverse this configuration to have the
AUI 2 port act as the primary bridge port.
TPXMIM - The EMME also supports Cabletron's family of Twisted Pair
Switching Media Interface Modules (TPXMIMs). These modules provide
board or individual port connectivity to any MMAC-FNB Ethernet
Channel (A, B, or C) with full SNMP management including RMON. All
ports initially default to Channel B upon power up and require a
Management Information Base (MIB) change to access any other
channel.
