CHAPTER 2 INSTALLATION This chapter describes how to unpack, configure, and install the BRIM-T6. Because the operation of a BRIM-T6 requires a properly attached and configured Token Ring Port Interface Module (TPIM), this chapter also includes TPIM configuration and installation instructions. CAUTION: Observe all precautions against electrostatic discharge when handling the BRIM-T6, TPIMs, and other network devices. Electrostatic discharge can damage a device’s processing components.
INSTALLATION 2.2.1 Installing the BRIM-T6 into a MIM To install the BRIM-T6 into a Media Interface Module (MIM), refer to Figure 2-1 and Figure 2-2 and follow these steps: 1. Disconnect all cables from the MIM as necessary. Note all prior cable-to-port connections to ensure proper reconnection. 2. Remove the MIM from the MMAC and place it on its side with its board components facing up. 3. Remove the BRIM receptacle coverplate from the MIM and the screws from the standoffs as shown in Figure 2-1.
INSTALLATION Standoff screw BRIM T6 MT bX 16M STB RCV Connector pins under BRIM Connector Coverplate screw 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 down firmly on the rear section of the BRIM until the pins slide all the way into the connector holes. 6. Fasten the BRIM securely to the MIM motherboard with the coverplate and standoff screws. See Section 2.
INSTALLATION 2.2.2 Installing the BRIM-T6 into a Standalone Device Standalone devices have 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 device. To install a BRIM into a standalone device: 1. Power off the device and remove its chassis cover. Refer to the documentation included with the host device for instructions on removing the chassis cover. 2.
INSTALLATION The BRIM-T6 default ring speed setting is 16 Mbps. The other available setting is 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. 2. Slide the jumper down over pins 2 and 3 to select a 16 Mbps setting or over pins 1 and 2 to select a 4 Mbps setting.
INSTALLATION 2.4 CONFIGURING AND INSTALLING TPIMs This section describes how 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/RO) communications. For use in the BRIM-T6 as a bridge/routing interface, however, they must be reconfigured to support Station port applications. Additionally, the TPIM-F2 and TPIM-F3 must be configured to support 802.5J lobe operations via fiber optic cable.

CHAPTER 3 CONNECTING TO THE NETWORK This chapter describes how to connect the following standard network cable types to the BRIM-T6: • Shielded Twisted Pair (STP) • 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.
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. RJ45 Port RJ45 Connector TPIM-T2 Connection Figure 3-2. Connecting a UTP Segment 3.3 CONNECTING FIBER OPTIC SEGMENTS Both the TPIM -F2 (for multimode) and TPIM-F3 (for single-mode) support connection to fiber optic segments.
CONNECTING TO THE NETWORK • Dust, dirt, and other contaminants on the ends of the connectors create data transmission problems. Avoid touching the ends of the connectors. If the ends become dirty, clean them with alcohol using a soft, clean, lint-free cloth. To connect a fiber optic segment to the TPIM-F2 /-F3, refer to Figure 3-3 and follow these steps: 1. Remove the protective plastic covers from the fiber optic ports on the module and from the connectors on each fiber strand. 2.

CHAPTER 4 MONITORING AND TROUBLESHOOTING This chapter describes how 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. 4.1 LANVIEW LEDS LANVIEW LEDs are Cabletron Systems’ built-in, visual diagnostic and status monitoring system.
MONITORING AND TROUBLESHOOTING XMT (Transmit) When flashing Green, XMT indicates that the BRIM-T6 is transmitting traffic to the Token Ring network. When solid Red, XMT indicates that the BRIM-T6 is disabled. When blinking Red, XMT indicates a speed fault condition, typically caused by a mismatch in ring speeds between the BRIM-T6 and the ring occupied by the device to which it is linked. See Section 2.3 for information about setting the correct ring speed.

APPENDIX B MEDIA SPECIFICATIONS AND REQUIREMENTS This Appendix provides information about cabling media (Fiber, STP, UTP) used with the BRIM-T6. B.1 FIBER OPTIC Table B-1 defines total signal attenuation tolerances for both single-mode and multimode fiber cabling. Both types of cabling have a typical constant attenuation rate per km of fiber cable, and each connector on the cable system contributes significant additional attenuation. Maximum drive distances define maximum allowable cable length. Table B-1.
MEDIA SPECIFICATIONS AND REQUIREMENTS B.2 SHIELDED TWISTED PAIR (STP) STP cable categories are listed as follows: • IBM Type 1 consists of two STP lengths of 22 AWG solid wire for data. There are three versions of Type 1: Indoor, Outdoor, and Plenum. It is typically used for the longest cable runs within the walls of buildings. • IBM Type 2 is similar to Type 1 data cable, but has four additional UTP lengths of 22 AWG solid wire carried outside of the shield casing.
MEDIA SPECIFICATIONS AND REQUIREMENTS Maximum Lobe Length Lobe length is the physical length of the cable connecting a station to its TCU port. Table B-3 shows maximum lobe length according to ring speed. The length figures are for total lengths of STP cable only. Maximum Trunk Lengths The maximum trunk cable length between active devices is equal to the maximum drive distance.
MEDIA SPECIFICATIONS AND REQUIREMENTS UTP consists of four pairs of 24 AWG solid wire for data or voice communication and is typically used to wire cable runs within the walls of buildings. In some installations, existing UTP building wiring can be used for Token Ring cabling. UTP cable must conform to the limits shown in Table B-4. Better grades of UTP cable known as supergrade or level 4 are now available.
MEDIA SPECIFICATIONS AND REQUIREMENTS Maximum Lobe Lengths The lobe length is the physical length of the cable connecting a station to its TCU port. Table B-5 shows maximum lobe length according to ring speed. Length figures are for total lengths of UTP cable only. Table B-5.
