Cabletron Systems EMM-E6 Ethernet Manual De Usuario

FDDI and Token Ring Modules - The EMM-E6 recognizes the 
following FDDI and Token Ring modules, but the EMM-E6 management 
does not provide control or statistics.

•

SNACMIM 

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 EMM-E6 will 
only recognize the Token Ring modules.

TPXMIM - The EMM-E6 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.

Ethernet Channel D is provided by one of the two redundant EPIM ports 
on the front panel of the EMM-E6. These EPIM ports provide the 
capability for the use of a variety of Ethernet transmission media 
connections, including twisted pair, fiber optic, and thick or thin Ethernet 
coaxial cable.

Either one of the EPIM ports can act as the bridge port to the external 
network. When the EMM-E6 is first powered up, the EPIM 1 port acts as 
the bridge port and the EPIM 2 port is off. Using the network 
management capabilities of the EMM-E6, you can reverse this 
configuration to have the EPIM 2 port act as the primary bridge port.
