    If you are unfamiliar with Cabletron Systems’ networking products, please read this manual completely to gain an understanding of the features and capabilities of the BRIM-T6. Also, you should have a general knowledge of Token Ring (IEEE 802.5) data communications networks and their physical layer components before operating the BRIM-T6.

  • Page 10: Introducing The Brim-T6

    Media Flexibility Used in conjunction with Cabletron Systems’ series of hot swappable TPIMs, the BRIM-T6 can be configured for connection to all standard network media. See Section 2.4 for instructions on how to configure and install TPIMs. Table 1-1 lists TPIMs and their corresponding media and connector types.
  • Page 11 The BRIM-T6 operates in compliance with the functional specifications of the 802.1d STA, which is included in the firmware of the host device in which the BRIM-T6 is installed. The STA is used to manage primary and backup bridges and to maintain the reliability of the multi-bridged internetwork by detecting and preventing potential data loops.

    6. Reinstall the device chassis cover and then power on the device. 2.3 CONFIGURING THE BRIM-T6 RING SPEED You must configure the BRIM-T6 ring speed to match the ring speed of the Token Ring to which it is physically linked. The BRIM-T6 ring speed setting does not, however, have to match the ring speed setting of its host device.
  • Page 19 4 Mbps. To configure the ring speed, refer to the settings illustrated in Figure 2-3 and follow these steps: 1. Remove the MIM from the MMAC; if the BRIM-T6 is installed in a standalone device, remove the chassis cover from the device to provide access to the BRIM-T6’s component board surface.

  • Page 20: Configuring And Installing Tpims

    Refer to the TPIM-F2/TPIM-F3 part number location shown in Figure 2-4 to determine functional compatibility with the BRIM-T6. To configure TPIMs for use with the BRIM-T6, refer to Figure 2-4 and follow these steps: 1. Move the RI/RO and Station switch on the TPIMs to the Station (S or STN) position using a blunt, narrow-tipped instrument such as a screwdriver or similar instrument.
  • Page 21 NOTE: If the switch locations on a TPIM do not match the example locations illustrated in Figure 2-4, refer to the TPIM Reference Card included with the TPIM. The TPIM Reference Card outlines switch locations and settings. For additional help, call Cabletron Systems Technical Support Department (see Section 1.5). Top View...

    • Unshielded Twisted Pair (UTP) • Fiber Optic NOTE: Remember that the BRIM-T6 is designed and configured for connection to network concentrator Station ports only. 3.1 CONNECTING STP SEGMENTS Both the TPIM-T1 and the TPIM-T4 support connection to STP cable segments.

  • Page 24: Connecting Utp Segments

    CONNECTING TO THE NETWORK 3.2 CONNECTING UTP SEGMENTS The TPIM-T2 provides an RJ45 interface for connecting UTP cable segments (see Appendix A for pinouts). To connect a UTP segment to a TPIM-T2, insert the RJ45 connector into the RJ45 port as shown in Figure 3-2. Figure 3-2.

  • Page 27: Chapter 4 Monitoring And Troubleshooting

    LANVIEW LEDs are Cabletron Systems’ built-in, visual diagnostic and status monitoring system. The comprehensive LANVIEW system for the BRIM-T6 consists of four LEDs (Light Emitting Diodes) on the face of the BRIM-T6 and one LED on the face of its attached TPIM (Figure 4-1).
  • Page 28 LNK (Media Link OK) on attached TPIM When solid Green, LNK indicates that a connection exists between the BRIM-T6 and a node at the other end of the media segment. When off, (or also when Red on the TPIM-T1/-T2/-T4) this LED indicates either that the BRIM-T6 is not connected to another device or that the port is not receiving a signal.

  • Page 29: Checking The Connection

    The LNK LED on the TPIM lights green when there is an established link between the BRIM-T6 and the device at the other end of the media connection. If, however, the LNK LED lights red or is not lighted, a link has not been established.
  • Page 30 Check that the connection meets the dB loss limit and media specifications outlined in Appendix B. • Check that the BRIM-T6 port is enabled through Local Management. Contact Cabletron Systems Technical Support if you still cannot establish a network link.
