  • Page 12: Overview

    Chapter 1: Introduction 1.1 OVERVIEW The FDDI 3F00-01 and the 3F55-01 are dual-attached modules that connect the ATX to a Fiber Distributed Data Interface (FDDI) network. Multiple 3F55-01s and 3F00-01s can be installed in one ATX. Both modules support a wide range of applications, such as intra-facility or campus backbones, and client/server configurations.

    CHAPTER 2 CONNECTING TO THE NETWORK The 3F00-01/3F55-01 can be installed in any slot, and more than one can be installed in your ATX. Refer to the ATX User Guide for instructions on how to unpack, power up, and check your ATX before continuing with this chapter.

  • Page 18: Dual-Attached Station

    Chapter 2: Connecting to the Network 2.1.1 Dual-attached Station A dual-attached station (DAS) is connected to both the primary and secondary FDDI rings. This is the preferred configuration, since it provides the full benefits of dual-ring operation, allowing the network to continue to operate if a station or cable fails.

  • Page 19: Dual-Homed Single-Attached Station

    Chapter 2: Connecting to the Network 2.1.2 Dual-homed Single-attached Station Dual-homing is a method of connecting concentrators and stations that permits an alternate or backup path to the dual ring in case the primary connection fails. The connection is normally made via dual-attached concentrators (DACs) which are connected to both the primary and secondary FDDI rings.

  • Page 20: Single-Attached Station

    Chapter 2: Connecting to the Network 2.1.3 Single-attached Station A single-attached station (SAS) is an FDDI station that uses only one connection (an S port) for connection to the FDDI ring. Figure 2-3 shows the ATX, with a 3F00-01 installed, configured as an SAS, connected to a master port of a dual-attached concentrator (DAC) on the main FDDI ring.

  • Page 21: Optical Bypass Switch

    Chapter 2: Connecting to the Network 2.1.4 Optical Bypass Switch An Optical Bypass Switch (OBS) may be used to provide added protection when the ATX is configured as a DAS. If an OBS is connected to the 3F00-01 or 3F55-01, and a failure occurs at the ATX, the OBS automatically isolates the ATX from the rest of the network by reconfiguring the FDDI dual rings as shown in Figure 2-4.

A MIC consists of two parts: • The MIC plug, which terminates the optical fiber cable • The MIC receptacle, which is on the FDDI node or station To ensure that the MIC plugs and MIC port receptacles are correctly mated, FDDI standards state that different types of MIC plugs and...

  • Page 25: A And B Keying

    Chapter 2: Connecting to the Network 2.3.1 A and B Keying To install the ATX as a DAS, the preferred configuration, a MIC A and MIC B are required. Figure 2-7 shows the keying scheme used to differentiate A and B MICs, which are identified on the 3F00-01 and 3F55-01 front panel as FDDI MIC A and FDDI MIC B respectively.

  • Page 26: M And S Keying

    Chapter 2: Connecting to the Network 2.3.2 M and S Keying MICs on concentrators are keyed as type M MICs to connect to a master port (for the attachment) of stations or other concentrators, and type S MICs to connect to a slave port (for attachment to the FDDI network). For M port connections the MIC key slot runs along the center of the connector.

  • Page 27: Connecting Dual-Attached Stations

    Chapter 2: Connecting to the Network 2.4.2 Connecting Dual-attached Stations The cable assembly consists of a fiber cable (either multimode or single mode, depending on the type of module you are using) with a MIC A plug on one end and a MIC B plug on the other end. Two cable assemblies are required for each ATX that you are connecting.

  • Page 28: Connecting Dual-Homed Single-Attached Stations

    Chapter 2: Connecting to the Network 2.4.3 Connecting Dual-homed Single-attached Stations Two cable assemblies are required for each ATX. One consists of a fiber cable with a MIC A plug on one end and a MIC M plug on the other end, and the second consists of a fiber cable with a MIC B plug on one end and a MIC M plug on the other end.

  • Page 29: Connecting The Optical Bypass Switch

    Chapter 2: Connecting to the Network You can use a MIC A plug and the FDDI MIC A receptacle instead of MIC B, in which case the equivalent RING A LEDs will be on. 2.4.5 Connecting the Optical Bypass Switch The OBS has three built-in cables with MIC A and MIC B plugs and a male RJ-11 connector for connecting to the 3F00-01 or 3F55-01.
