2-1 CHAPTER 2 INST ALLA TION This chapter describes ho w to unpack, configure, and install the BRIM-T6. Because the operation of a BRIM-T6 requires a properly attached and configured T oken Ring Port Interface Module (TPIM), this chapter also includes TPIM configuration and installation instructions.
INST ALLA TION 2-2 2.2.1 Installing the BRIM-T6 into a MIM T o install the BRIM-T6 into a Media Interface Module (MIM), refer to Figure 2-1 and Figure 2-2 and follo w these steps: 1. Disconnect all cables from the MIM as necessary . Note all prior cable-to-port connections to ensure proper reconnection.
INST ALLA TION 2-3 Figure 2-2. Installing the BRIM-T6 5. Insert the connector pins on the underside of the BRIM into the motherboard connector on the MIM by pressing do wn firmly on the rear section of the BRIM until the pins slide all the way into the connector holes.
INST ALLA TION 2-4 2.2.2 Installing the BRIM-T6 into a Standalone Device Standalone de vices hav e the same physical setup for BRIM installation as MIMs. So you can refer to Figure 2-1 and Figure 2-2 when installing a BRIM-T6 into a standalone de vice.
INST ALLA TION 2-5 The BRIM-T6 default ring speed setting is 16 Mbps. The other av ailable setting is 4 Mbps. T o configure the ring speed, refer to the settings illustrated in Figure 2-3 and follo w these steps: 1.
INST ALLA TION 2-6 2.4 CONFIGURING AND INST ALLING TPIMs This section describes ho w to configure TPIMs and install them into the BRIM-T6. 2.4.1 Configuring TPIMs Cabletron TPIMs are shipped pre-configured to support Ring In/Ring Out (RI/R O) communications.
INST ALLA TION 2-7 Figure 2-4. TPIM Configuration for Station Applications NO TE : If the switch locations on a TPIM do not match the example locations illustrated in Figur e 2-4, r efer to the TPIM Refer ence Card included with the TPIM. The TPIM Refer ence Car d outlines switch locations and settings.
INST ALLA TION 2-8 2.4.2 Installing TPIMs T o install a TPIM into the BRIM-T6, refer to Figure 2-5 and follo w these steps: 1. Slide the TPIM into the TPIM slots until the connector pins in the BRIM are fully inserted into the connector on the TPIM. 2.
3-1 CHAPTER 3 CONNECTING T O THE NETW ORK This chapter describes ho w to connect the follo wing standard network cable types to the BRIM-T6: • Shielded T wisted Pair (STP) • Unshielded T wisted Pair (UTP) • Fiber Optic NO TE : Remember that the BRIM-T6 is designed and configur ed for connection to network concentrator Station ports only .
CONNECTING T O THE NETWORK 3-2 3.2 CONNECTING UTP SEGMENTS The TPIM-T2 pro vides an RJ45 interface for connecting UTP cable segments (see Appendix A for pinouts). T o connect a UTP segment to a TPIM-T2, insert the RJ45 connector into the RJ45 port as sho wn in Figure 3-2.
CONNECTING T O THE NETWORK 3-3 • Dust, dirt, and other contaminants on the ends of the connectors create data transmission problems. A void touching the ends of the connectors. If the ends become dirty , clean them with alcohol using a soft, clean, lint-free cloth.
CONNECTING T O THE NETWORK 3-4.
4-1 CHAPTER 4 MONIT ORING AND TROUBLESHOO TING This chapter describes ho w to use the LANVIEW LED system to monitor the operation of the BRIM-T6. It also describes procedures for resolving problems you may encounter establishing a link to a network via the BRIM-T6 interface.
MONIT ORING AND TR OUBLESHOO TING 4-2 XMT (T ransmit) When flashing Green, XMT indicates that the BRIM-T6 is transmitting traf fic to the T oken Ring network.
MONIT ORING AND TR OUBLESHOO TING 4-3 4.2 CHECKING THE CONNECTION This section provides a checklist for troubleshooting netw ork connection problems. The LNK LED on the TPIM lights green when there is an established link between the BRIM-T6 and the de vice at the other end of the media connection.
MONIT ORING AND TR OUBLESHOO TING 4-4 • V erify that STP and UTP connectors (DB9 and RJ45) are pinned properly . For fiber , verify that the recei ve-to-transmit connection of strands between de vices is correct. • Check that the connection meets the dB loss limit and media specifications outlined in Appendix B.
