INTRODUCTION

Jumper Selectable Ring Speed

The BRIM-T6 has a ring speed selection jumper on its component board that you can use to select operating ring speeds of either 4 or 16 megabits per second (4 or 16 Mbps). See Section 2.3 for instructions on setting the ring speed for the BRIM-T6.

Bridge/Routing Protocols

The BRIM-T6 provides Source Routing Transparent (SRT) bridging between any of the channels or ports in its host MIM or hub and the Token Ring. BRIM-T6 routing is determined by the routing protocols supported by the ﬁrmware of the host device.

Spanning Tree Algorithm (STA) Compliance

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.

BRIM-T6 Management

The host device in which the BRIM-T6 is installed provides Local Management (LM) applications for administering BRIM-T6 bridge/routing functions. The operation of the BRIM-T6 can also be managed by remote SNMP applications such as Remote LANVIEW and SPECTRUM. See the documentation included with the host device or remote management application for information on how to administer bridge/routing functions.

LANVIEW LEDs

The LANVIEW LEDs on the front panel of the BRIM-T6, together with the LED on an installed TPIM, provide an at-a-glance means of monitoring the operational status of the BRIM-T6. LEDs indicate, for example, network connection status, data transmission activity, and ring speed operation. See Chapter 4 for more information about LEDs.

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.

NOTE: TPIM-F2 har dware version 04 and TPIM-F3 har dwar e version 02 or higher must be used to provide bridge links via ﬁber optic cable. Prior versions do not support this functionality with the BRIM-T6.

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.

2. Move the Fiber Key to the 802.5 setting for the TPIM-F2 and TPIM-F3 using the same instrument.

Leave the Phantom Switch setting in the default position for the TPIM-T1, TPIM-T2, and TPIM-T4.

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. The TPIM-T1 provides a DB9 interface, and the TPIM-T4 provides an RJ45 interface (see Appendix A for pinouts).

To connect an STP segment to a TPIM-T1 or a TPIM-T4, insert the DB9 or RJ45 connector into its corresponding TPIM port as shown in Figure 3-1.

3.3 CONNECTING FIBER OPTIC SEGMENTS

Both the TPIM -F2 (for multimode) and TPIM-F3 (for single-mode) support connection to ﬁber optic segments. When connecting a segment to the TPIM-F2 or TPIM-F3, consider the following:

• Fiber optic segments with Straight Tip (ST) connectors attach to ST ports much like BNC connectors attach to BNC ports. The connector must be inserted into the port with the alignment key on the connector inserted into the alignment slot on the port. Then the connector must be turned to lock it down.

• The physical communication link consists of two strands of ﬁber optic cabling. The T ransmit strand (TX) at one end connects to the Receive (RX) port at the other end and vice versa.

3-2

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. Attach a ﬁber strand to the module’s receive port (labeled RX) and the

other ﬁber strand to the module’s transmit port (labeled TX).

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. 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).

4.1.1 Describing BRIM-T6 LEDs

The information conve yed by each LED about the operational status of the BRIM-T6 is described as follows (also see Table 4-1 summary):

16Mb (Ring Speed)

When solid Yellow, 16Mb indicates that the BRIM-T6 ring speed is set to 16 Mbps. When off, it indicates that the ring speed is set to 4 Mbps.

4-1

MONITORING AND TROUBLESHOOTING

XMT (Transmit)

When ﬂashing Green, XMT indicates that the BRIM-T6 is transmitting trafﬁc to the T ok en 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.

RCV (Receive)

When solid Green, RCV indicates that the BRIM-T6 is currently enabled to receive Token Ring trafﬁc, and when ﬂashing Yellow , it indicates that it is currently receiving Token Ring trafﬁc. When solid Red, RCV indicates that the BRIM-T6 is disabled by the host device.

STB (Standby)

When solid Yellow, STB indicates a standby condition: the BRIM-T6 is not ready or able to transmit data to the ring. Standby conditions are caused, typically, when the host device is initializing or when a TPIM is not attached to the BRIM-T6.

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 of f, (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.

4.2 CHECKING THE CONNECTION

This section provides a checklist for troubleshooting network connection problems.

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. To resolve the problem, try the following procedures:

• Check that the host device and the device at the other end of the segment have power.

• Check that the TPIM is securely installed in the BRIM-T6 and that the BRIM-T6 is securely installed in the host device.

• Check for correct connector-to-port attachments at the BRIM-T6 and the destination device.

• Inspect the cabling system (cable and connectors) for damage and replace damaged components.

4-3

MONITORING AND TROUBLESHOOTING

• Verify that STP and UTP connectors (DB9 and RJ45) are pinned properly. For ﬁber, verify that the receive-to-transmit connection of strands between devices is correct.

• 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.

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.

MEDIA SPECIFICATIONS AND REQUIREMENTS

B.2 SHIELDED TWISTED PAIR (STP)

STP cable categories are listed as follows:

• IBM T ype 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 T ype 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. There are two versions of Type 2: Plenum and Outdoor. It is typically used for voice communication and often used to wire cable runs within the walls of buildings.

• IBM T ype 6 consists of two STP lengths of 26 AWG stranded wire for data. Used in patch panels or to connect devices to/from wall jacks. Attenuation for Type 6 cable is 150% of Type 1 cable (e.g., 66 m of Type 6 =100 meters of Type 1).

• IBM T ype 9 is similar to Type 1, but uses 26 AWG solid wire. Attenuation for Type 9 cable is 150% of Type 1 cable (e.g., 66 m of Type 9 = 100 meters of Type 1).

Impedance and Attentuation

The attenuation values shown Table B-2 include the attenuation of the cables, connectors, patch panels, and reﬂection losses due to impedance mismatches in the segment.

MEDIA SPECIFICATIONS AND REQUIREMENTS

Maximum Lobe Length

Lobe length is the physical length of the cable connecting a station to its TCU port. T able B-3 shows maximum lobe length according to ring speed. The length ﬁgures are for total lengths of STP cable only.

Maximum T runk Lengths

The maximum trunk cable length between active devices is equal to the maximum drive distance. When the neighboring device is passive, the Maximum Drive Distance must not exceed the combined length of twice the longest trunk cable plus the longest lobe cable attached to the passive ring segment (see Table B-3).

NOTE: IBM Types 6 & 9 are to be used only for lobe connections from station to wall jack and patch panels.

B.3 UNSHIELDED TWISTED PAIR (UTP)

TPIM-T2 supports voice-grade UTP cable (as described in EIA/TIA TSB

568) and IBM Type 3 cable.

WARNING: Do not connect UTP cabling to any non-Token Ring network conductors (telephone, etc.) or ground. If in doubt, test wiring before using. Telephone battery and ringing voltages used in UTP telephone circuits may present a shock hazard and may damage Token Ring equipment when connected to token ring cabling.

B-3

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. These improved grades of UTP can often be used to permit operation at 16 Mbps on longer lobe cables.

Attenuation and Impedance

The attenuation values shown in Table B-4 include the attenuation of the cables, connectors, patch panels, and reﬂection losses due to impedance mismatches in the segment.
