1.2TPXMIM FEATURES
LANVIEW
Cabletron provides a visual diagnostic and status monitoring system,
called LANVIEW, with the TPXMIM. LANVIEW LEDs help you
quickly identify device, port, and physical layer problems.
“Switching”
The TPXMIM brings “bank switching” and individual “port assignment”
to the MMAC chassis. Using any multi-channel management module
(i.e., the EMME or EMM-E6), you can assign either the entire board
(bank switching) or each individual port (port assignment) to any of the
three Ethernet channels on the MMAC-FNB (i.e., Channel A, B, or C).
Connectivity
The TPXMIM series offers four connector versions:
•TPXMIM-20 — nine RJ45 ports; one EPIM port
•TPXMIM-22 — twenty-one RJ45 ports; one EPIM port
•TPXMIM-33 — one 50-pin Champ connector; one EPIM port
•TPXMIM-34 — two 50-pin Champ connectors; one EPIM port

TPXMIM Installation Guide
OVERVIEW
MIB Navigation
Assigning the TPXMIM board or individual ports to specific Ethernet
channels, or obtaining TPXMIM board or port statistics, requires a multichannel management device (e.g., EMME or EMM-E6) and access to a
MIB walking tool. The EMME or EMM-E6 allows MIB access both
locally (i.e., Local Management) and remotely (i.e., additional Cabletron
Remote Management packages).
For information on how to use the Local Management MIB w alking tool,
refer to either the EMME or EMM-E6 Local Management manual. For
information on how to use a Remote Management MIB walking tool,
refer to documentation specific to that Remote Management package.
Compliance
Each TPXMIM utilizes Repeater Interface Controller (RIC) technology.
RIC technology integrates all repeater functionality into one integrated
circuit. This makes the TPXMIM fully 10Base-T IEEE 802.3i compliant.
Fault Tolerance
By performing its own repeater functions, the TPXMIM greatly enhances
the fault tolerance of the MMA C. By not relying on one central module to
perform repeater functions, TPXMIMs eliminate a single point of failure.
In addition, the TPXMIM provides port segment partitioning and
reconnection. This feature assures that problem segments do not affect
any other segments. If the TPXMIM detects 31 consecutive collisions on
µ
any segment, or if a collision detector remains on for more than 110
s,
the TPXMIM automatically partitions that segment. When the TPXMIM
receives a good packet from the segment, it automatically reconnects.
1.3OVERVIEW
The
Twisted Pair Switching Media Interface Module (TPXMIM)
provides board or individual port connectivity to any MMAC-FNB
Ethernet Channel (i.e., Channels A, B, or C). All ports initially default to
Channel B upon power up and require a Management Information Base
(MIB) change to access any other channel. Refer to Chapter 3,
Installation/Configuration
, for additional information on how to assign
the TPXMIM board or individual ports to specific channels.
TPXMIM Installation Guide
Page 3
CHAPTER 1:
INTRODUCTION
The TPXMIM repeats (regenerates, retimes, and transmits) each packet it
receives, assuring data integrity and maximum data path distance. Using
Repeater Interface Controller (RIC) technology, each TPXMIM complies
fully with the 10Base-T IEEE 802.3i standard connectivity for Ethernet
communications over shielded or unshielded twisted pair cabling.
In addition to providing full connectivity to the MMAC backplane, each
TPXMIM provides the option of installing an external Ethernet Port
Interface Module (EPIM). Each TPXMIM provides one slot on the front
panel for your choice of an optional EPIM. EPIMs provide an additional
Ethernet connection for various media types (twisted pair, fiber optic, and
thick or thin Ethernet coaxial cable). The following list contains the
currently available EPIMs and their media types:
EPIM-T
•
EPIM-F1/EPIM-F2
•
: 10Base-T Twisted Pair Segment Interface Module
: Multimode Fiber Optic Segment
Interface Modules using SMA/ST style connectors
EPIM-F3
•
EPIM-C
•
EPIM-A/EPIM-X
•
: Single Mode Fiber Optic Segment Interface Module
: Thin-net Coaxial Segment Interface Module
: AUI Cable Segment Interface Modules
Since the TPXMIM is SNMP compliant, you can control and monitor the
device using various SNMP Network Management packages including
Cabletron Systems’
SPECTRUM® Portable Management Applications
(SPMA) products.
1.4THE TPXMIM AND MANAGEMENT MODULES
The TPXMIM requires a multichannel management module (i.e., EMME,
EMM-E6, etc.) in slot #1 (farthest right slot) of the MMAC. The multichannel management module provides the capability of setting the board
or individual ports to Channels other than Channel B (default), and
repeating to any Channel (i.e., Channel A, B, or C). In addition, the use of
a multi-channel management module provides helpful statistical
information for the TPXMIM including:
•the number of bytes received
•the number of frames received, filtered, and transmitted
•the total number of errors and a breakdown of those errors.
Page 4
TPXMIM Installation Guide
THE TPXMIM AND MMAC BACKPLANE
Multi-channel management modules provide bridging and optional
routing control for Ethernet Channels A, B, and C on the MMAC
backplane, and Channel D from the module faceplate. All Channels
access the same shared memory, allowing a management module to
bridge any or all packets it receives for any given Channel. In addition,
the EMM-E6 provides options for two additional Ethernet connections
(channels E and F) that access WAN, ATM or FDDI networks.
For additional information regarding the EMME or EMM-E6, refer to
specific module documentation.
1.5THE TPXMIM AND MMAC BACKPLANE
The Multi Media Access Center with Flexible Network Bus
(MMAC-FNB) provides the TPXMIM with power, Ethernet A Bus
(Channel A), and FNB (Channel B and C) access (Figure 1-1).
Power & Management Bus

Flexible Network Bus
Ethernet B Bus
Ethernet C Bus
Figure 1-1. MMAC Flexible Network Bus
Two types of MMACs currently support FNB architecture — shunting
and non-shunting. MMACs equipped with shunting backplanes allow
modules operating on the B or C bus to continue communicating
regardless of whether there is an empty slot or an A Channel module
between them in the chassis. The following table gives the part numbers
of the MMAC chassis that have shunting capabilities.
