TPXMIM Installation Guide
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
: 10Base-T Twisted Pair Segment Interface Module
•
EPIM-F1/EPIM-F2
: Multimode Fiber Optic Segment
Interface Modules using SMA/ST style connectors
•
EPIM-F3
: Single Mode Fiber Optic Segment Interface Module
•
EPIM-C
: Thin-net Coaxial Segment Interface Module
•
EPIM-A/EPIM-X
: 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

THE 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 multi-
channel 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.
