Either thick or thin Ethernet cable can be connected to the THN-MIM. Thin-net cable segments, using 50 ohm Ethernet type cable, can be connected directly to the module. Each of these segments can be up to 185 meters in length and can support up to 29 users. -

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. The IRM can be accessed directly through a... - Page 8 50 ohm terminator in the port. Each segment connector shield is internally connected to earth ground by the THN-MIM. This eliminates the need for grounding the segments connected to the BNC ports. Indicates that the port is connected to the network.

Connection to earth ground at more than one point on the segment may allow for the occurrence of dangerous ground currents. The BNC ports of the THN-MIM are connected to earth ground. This eliminates the need of grounding the thin-net segments connected to the module. -

INSTALLATION 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. 2.2.2 Thin-net Segments (THN-MIM7593 only) The following network design guideline must be followed when connecting 75 or 93 ohm coaxial cable segments to the THN-MIM7593. -

Connection to earth ground at more than one point on the segment may allow for the occurrence of dangerous ground currents. The BNC ports of the THN-MIM are connected to earth ground. This eliminates the need for grounding a thick-net segment connected to the module. -

4. Slide the module into the MMAC card cage. 5. Secure the module to the MMAC by turning the knurled knobs. CAUTION: Be sure the THN-MIM is firmly attached to the MMAC by turning the knurled knobs. Failure to do so may result in improper operation. -

3.2 INSTALLATION CHECK-OUT This section contains procedures to test that the physical layer of the network and a coaxial segment connected to the THN-MIM are operating properly. This section also contains procedures to check that the physical layer of the network is operating properly. An Ethernet node tester that will generate valid data packets, such as Cabletron Systems LAN-MD, is required for this procedure. -
Page 15: Using Lanview
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. If any failures were noted, please contact Cabletron Systems Technical Support.
