- Page 10 INTRODUCTION Speed Fault Protection If a station attempts to inserting into the ring at a ring speed (4 or 16 mbits) different from what is set on the TRMIM, that port is automatically bypassed to prevent the ring from beaconing. The PEN LED flashes indicating the port with the speed fault is bypassed.

Page 13: Chapter 2 Installation Requirements/Specifications
2.1.1 Cable Specifications The media used for station (lobe) cabling depends on your specific concentrator module: • The TRMIM-22A and TRMIM-24A support voice grade UTP cable, as described in EIA Standard Proposal No. 1907-A, and IBM Type 3 UTP cabling. - Page 14 (STP) cable Types 1, 2, 6, and 9 at their trunk coupling unit (TCU) ports. UTP CABLE TYPES Both UTP concentrator modules (TRMIM-22A & 24A) support D-inside wiring (DIW) voice grade Unshielded Twisted Pair (UTP) cable as described in EIA SP-1907B. Voice grade UTP cabling (e.g.
- Page 15 When connecting token ring devices that are not equipped with a Type 3 Media Filter to either of the active UTP concentrator modules (TRMIM-22A/24A), a Type 3 Media Filter, such as the Cabletron Systems TRMF or TRMF-2, must be installed in line with the lobe cable at the connection to token ring station.
- Page 16 REQUIREMENTS/SPECIFICATIONS Table 2-2 IBM Cable Types Type 1 Two shielded twisted pairs (STP) of 22 AWG solid wire for data. Used for the longest cable runs within the walls of buildings. Type 2 Similar to Type 1 data cable, but having four additional unshielded twisted pairs of 22 AWG solid wire.

REQUIREMENTS/SPECIFICATIONS — 16 Mbit/s ring speed and 130 stations. — The building has 60 meters of Type 1 cable in the wall. — What is the length of Type 6 cable available to connect from the TCU port to the patch panel and from the local wall jack to the station? —... - Page 19 Noise can be caused by either crosstalk or externally induced impulses. If noise induced errors are suspected, it may be necessary to re-route cabling away from potential noise sources (motors, switching equipment, fluorescent lighting, high amperage equipment), or to ensure that the electrical wiring in the area is properly wired and grounded.

Page 20: Maximum Number Of Stations
REQUIREMENTS/SPECIFICATIONS • For single telecommunications closet rings, lobe lengths should not exceed 100 meters or 22 to 24 AWG wire from the attaching device and the TCU port. • When possible, use dedicated UTP cable for token ring signals. 2.2 MAXIMUM NUMBER OF STATIONS The maximum number of stations in a single ring, using UTP lobe cabling is 150 stations using category 5 cabling or 100 stations using category 3 or 4 cabling. - Page 21 TRMIM-22A/TRMIM-24A RX– MALE RJ-45 TX– Figure 2-2 Concentrator Module TCU Port Pinouts The shield continuity is maintained by contacts within the female RJ-45 that contact the metallic casing of the male RJ-45 on the STP lobe cabling. Shielded patch cables that adapt a shielded RJ-45 to a Data Connector (MIC) are available from Cabletron Systems in eight foot lengths.

Page 22: Ring Speed
Ring boards via the FNB, the ring order is in MMAC slot number order, and then port number order within each Token Ring board. Example: TRMIM-22A in slot 1 with ports 2, 5, 8, & 12 in use. TRMIM-22A in slot 2 with ports 1, 5, 7, 11, & 12 in use. - Page 23 modules are equipped with the same indicators. Three concentrator-specific LEDs indicate the current ring speed (16MB), error status (ERR), and the current mode, management (MGMT) or automatic, and two port-specific LEDs per port that indicate Port Enabled (PEN) and Port Linked (LNK) status. These are illustrated in Figure 2-4.

Page 25: Chapter 3 Installing The Concentrator Module
CONCENTRATOR MODULE This chapter contains instructions for installing your concentrator module into a Cabletron Systems MMAC product and connecting token ring stations at the concentrator module’s trunk coupling unit (TCU) ports. Check that all requirements listed in Chapter 2, Installation Requirements/ Specifications, have been met before installing and operating the concentrator module. -
Page 26: Unpacking The Concentrator Module
INSTALLING THE CONCENTRATOR MODULE NOTE: The FNB is a full-height, full-width backplane that links Cabletron Systems Token Ring products. MMAC-3s and MMAC-8s (without an FNB) can be upgraded with an FNB, providing greater flexibility in configuring your system. Contact Cabletron Systems Technical Support for more information. -
Page 27: Configuring The Concentrator Module
3.2 CONFIGURING THE CONCENTRATOR MODULE Position the hardware jumper on the proper pins on the concentrator module to select either 4 or 16 Mbit/s as the default network ring speed (see Figure 3-1). The speed setting is a factor in determining the maximum lobe length. -

TESTING AND TROUBLESHOOTING This section contains procedures to verify that the connections between the concentrator module and the token ring stations are functioning properly. A description of the LANVIEW LEDs is also provided. INSTALLATION CHECKOUT Perform the following to check the installation of the concentrator module: 1. - Page 34 TRMIM-24A is shown in the illustration, the locations and definitions apply to all four concentrator modules, except that for the TRMIM-22A and TRMIM-42A, ports 13 through 24 and the LEDs associated with them are not present. • 16MB - The Ring Speed LED (Yellow) is lit to indicate that the concentrator module ring speed is set to 16 Mbit/s.
- Page 35 • ERR - The error indicator (Red) should not be lit under normal operating conditions. When lit this LED indicates one of the ports is bypassed due to a ring speed error (a device at one of the ports is set to the wrong ring speed) or the detection of a concentrator module hardware failure.
- Page 36 TESTING AND TROUBLESHOOTING station has removed phantom current from the TCU port connection. If the port has been made a Ring-Out port by the MMAC management module, the LNK LED stays lit even with no connection. • MGMT - Management (Green) when lit, indicates that the concentrator module is in Management Mode.
