Page 7: Getting Help
INTRODUCTION Chapter 4, Testing and Troubleshooting, provides procedures for testing and troubleshooting the installation of the TPMIM. Instructions for using LAN- ® VIEW , Cabletron Systems’ built-in visual diagnostic and status monitoring sys- tem, are also included. We assume that you have a general working knowledge of Ethernet or IEEE 802.3 type data communications networks and their physical layer components. - Page 8 INTRODUCTION Polarity Detection and Correction Each Port on the TPMIM incorporates a Polarity Detection and Correction fea- ture. The Polarity Detection and Correction feature allows the TPMIM to pass data regardless of the polarity of the twisted pair segments’ receive link. If polar- ity is reversed, the LNK LED will flash to indicate this condition, once a good packet passes through the port.

The TPMIM-22/24 design incorporates built-in RJ-45 ports, 12 on the TPMIM- 22 and 24 on the TPMIM-24. This design makes it easier to incorporate twisted pair wiring schemes into your network. The TPMIM-22/24 allows you to directly connect the segments to patch panels or other 10BASE-T Ethernet devices, elim- inating the need for Punch-Down blocks or additional patch panels. -

INTRODUCTION 1.3.2The TPMIM-32/34 The TPMIM-32/34 provides an alternative method for incorporating 10BASE-T twisted pair segments into an existing twisted pair wiring scheme. The TPMIM- 32 has one 50 pin Champ connector that allows you to connect 12 segments to the module. -
Page 11: Installation Requirements/Specifications
INSTALLATION REQUIREMENTS/SPECIFICATIONS Before you attempt to install the Cabletron Systems 10BASE-T Twisted Pair Me- dia Interface Modules, review the network requirements that are outlined in this chapter. Also, refer to the operating specifications that are listed. All conditions, guidelines, specifications, and requirements included in this chap- ter must be met to ensure satisfactory performance of the TPMIM. - Page 12 • Insertion Loss - The maximum insertion loss allowed for a 10BASE-T link is 11.5 dB at all frequencies between 5.0 and 10.0 MHz. This includes the attenuation of the cables, connectors, patch panels, and reflection losses due to impedance mismatches in the link segment. •...

INSTALLING THE TPMIM This chapter contains instructions for installing the Cabletron Systems 10BASE- T Twisted Pair Media Interface Module (TPMIM) into any of Cabletron Systems' MMACs. Instructions for connecting twisted pair segments to the MIM are also included. Check that all requirements listed in Chapter 2, Installation Require- ments/Specifications, are met before installing the MIM. - Page 18 • If installing a TPMIM-24/34, an IRM-2 or an IRBM must be installed Slot • If the module is going to be installed into an MMAC-8™/MMAC-8FNB™/MMAC-5FNB™, be sure a Power Supply Module (PSM-R™, or MMAC-5PSM™) is installed in the MMAC to supply power to the module.

Page 19: Connecting The Tpmim To The Network
MMAC. 3.3.1 Attaching Twisted Pair Segments to the TPMIM-22/24 The TPMIM-22 has 12 RJ-45 ports, while the TPMIM-24 has 24 RJ-45 ports. This provides easy connection of unshielded twisted pair segments to the MIM. Each port on the module is internally crossed over. This is indicated by an X next to the port. -

Cable Pinouts - TPMIM-22/24 3.3.2 Attaching Twisted Pair Segments to the TPMIM-32/34 The TPMIM-32 has a 50 pin Champ connector, while the TPMIM-34 has two 50- pin Champ connectors. - Page 21 As an aid, three tables and one figure have been included with this section. Table 3-1 describes the pins and the color codes that are used in twisted wiring from the TPMIM-32/34 and a punch down block. Table 3-2 describes the pins and the col- or codes that are used from a punch down block to a 10BASE-T Ethernet device.
- Page 22 If the Link LED is flashing, once a good packet passes through the port, this indi- cates that the polarity of the twisted pair segments’ receive link is reversed. If this condition exists, the segment should be removed from the TPMIM and the wiring corrected in the event that, in the future, the segment needs to be attached to a de- vice without the Polarity Correction and Detection feature.

CHAPTER 4 TESTING AND LANVIEW This section contains procedures to ensure that the connection between the TP- MIM and the 10BASE-T Ethernet device is functioning properly. A description of LANVIEW and its function in troubleshooting physical layer network prob- lems is also provided. INSTALLATION CHECK-OUT You should test the TPMIM after installation to ensure that the physical layer of the network is operating properly. - Page 34 LAN-MD Segment AUI Cable Twisted Pair Segment MMAC-8 Figure 4-1. Sample Installation Check-Out Configuration 6. Using another transceiver (7) and AUI cable (8), connect another LAN-MD (9) to any other tested segment that is connected to an MMAC. 7. Select and run test 4 - NODE on the LAN-MD connected in step 6. Verify that this test passes.

Page 35: Using Lanview
TESTING AND LANVIEW 4.2 USING LANVIEW The TPMIM uses Cabletron Systems built-in visual diagnostic and status moni- toring system, LANVIEW. Using LANVIEW LEDs, your network troubleshoot- ing personnel can quickly scan the LEDs to observe network status or diagnose network problems, and determine which node or segment is faulty. The following section discusses the function and the purpose of each LANVIEW LED on the TPMIM. - Page 36 TESTING AND LANVIEW LINK OK (LNK) When lit, this green LED indicates that a link has been established between the TPMIM and the 10BASE-T device at the other end of the twisted pair segment. This LED remains lit as long as the link is maintained. If no data has been sent for 16 msec, a positive link test pulse of 100 nsec is sent onto the transmit link of the twisted pair cable.
