INTRODUCTION Page 1-1 CHAPTER 1 INTRODUCTION 1.1 INTRODUCTION Cabletron Systems Coaxial Media Interface Module (THN-MIM) provides 12 Ethernet/lEEE 802.3 coaxial cable connectors per module. When used with the MMAC-8 ™ enclosure, up to 84 coaxial segments can be connected to one MMAC ™ .
INTRODUCTION Page 1-2 can be connected directly to the module. Each of these segments supports one device. The entire THN-MIM or each port on the MIM can be controlled via the IRM in your MMAC.
INTRODUCTION Page 1-3 NOTE: Cabletron Systems reserves the right to change these specifications at any time without notice. BNC INTERFACE (Ports 1-12) Type: BNC receptacle, with gold center contact, for use with BNC type plugs and RG-58 thin-net cable.
INTRODUCTION Page 1-4 SAFETY WARNING: It is the responsibility of the person who sells the system of which the THN-MIM will be a part, to ensure that the total system meets allowed limits of conducted and radiated emissions. Designed in accordance with UL478, UL910, NEC 725-2(b), CSA, IEC, TUV, VDE class A.
INSTALLATION Page 2-1 CHAPTER 2 INST ALLA TION 2.1 INTRODUCTION The Cabletron Systems THN-MIM is designed for quick and easy installation into an MMAC. No special skills or tools are required to install this module. 2.2 NETWORK DESIGN GUIDELINES The following network design guidelines must be followed when connecting segments to the THN-MIM.
INSTALLATION Page 2-2 Since the ports on the module are internally terminated, the end of the segment that will be connected to the module will not be a tee connector or terminator.
INSTALLATION Page 2-3 • The THN-MIM7593 does not report false collisions to the IRM. However, if a non-Cabletron Systems Ethernet device is connected to the segment, it is possible for false collisions to be generated. Non-Cabletron System devices should be thoroughly tested before using them with the THN-MIM7593.
INSTALLATION Page 2-4 2.3 INSTALLATION Install the THN-MIM into the MMAC as follows: CAUTION: Observe all electrostatic precautions when handling the THN-MIM. Static discharges will damage the module. 1. Remove the unit from the shipping box. 2. Slide the two foam end caps off the unit.
TESTING AND LANVIEW Page 3-1 CHAPTER 3 TESTING AND LANVIEW 3.1 INTRODUCTION This section lists procedures to ensure that the segments connected to the Cabletron Systems THN-MIM are operating properly. A description of LANVIEW LEDs and their function in troubleshooting physical layer network problems are also provided.
TESTING AND LANVIEW Page 3-2 At least 100 packets should be sent and received with no errors. The packets will be received from and sent back to the LAN-MD acting as the SERVER . When the applicable segment(s) connected to the THN-MIM have successfully completed these tests, the segments are ready for normal operation.
