Page 10: Overview
OVERVIEW MIB Navigation Assigning the TPXMIM board or individual ports to specific Ethernet channels, or obtaining TPXMIM board or port statistics, requires a multi- channel 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). -
Page 11: The Tpxmim And Management Modules
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. -
Page 12: The Tpxmim And Mmac Backplane
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. -
Page 13: Lanview Leds
The TPXMIM incorporates the Cabletron Systems LANVIEW Monitoring and Diagnostics System. LANVIEW LEDs can help diagnose any problems, such as a power failure or a cable fault. Each port on the TPXMIM-20/22 modules include the following LANVIEW LEDs: • a RCV (receive) LED to indicate network activity on the port •... -
Page 14: Network Management Capabilities
• a SEL (select) LED to indicate port association selection of the EPIM port. The SEL LED on the TPXMIM-33 is always lit since the EPIM is always active. However, the TPXMIM-34 provides the software selectable option of using the EPIM instead of 10Base-T Champ connector port 13. -

Use the Output Power Coefficient to calculate increased or decreased power output for your operating environment. For example, typical power output at 25ºC equals -16.4 dBm. For a 4ºC temperature increase, multiply the typical coefficient (-0.15 dBm) by four, and add the result to typical output power (4 x -0.15 dBm + -16.4 dBm = -17.0 dBm).
