CHAPTER 1 INTRODUCTION This manual is for system administrators responsible for configuring, monitoring, and maintaining the ATX. It should be used with the ATX User Guide and the ATX MIB Reference Guide. The contents of each chapter are described below. • Chapter 1, Introduction, outlines the contents of this manual and provides an overview of the 3F00-01 and 3F55-01. • Chapter 2, Connecting to the Network, describes how to physically attach the module to a network.
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 1: Introduction an external Optical Bypass Switch (OBS) that allows full FDDI operation to continue if the ATX is disabled. Both FDDI standard station management (SMT) and SNMP are supported, allowing you to use a variety of network management software to configure your 3F00-01/3F55-01 and monitor your network. Both the 3F00-01 and 3F55-01 are protected by a built-in temperature sensor that sends an alarm if the module overheats.
Chapter 1: Introduction 1.
Chapter 1: Introduction Information that you need to enter with a command is enclosed in angle brackets < >.

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. Instructions for installing or swapping an 3F00-01 or 3F55-01 are included in Chapter 6, Adding/Swapping Modules. 2.
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. Figure 2-1 shows the ATX, with a 3F00-01 installed, connected as a DAS to two other DASs in an FDDI network. (A and B indicate A port and B port.
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. Other FDDI stations or concentrators are connected to the DAC master (M) ports.
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. Network DAS DAC M M M SAS SAS Port B bp s B ET G R 1.
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.
Chapter 2: Connecting to the Network 2.2.1 3F00-01 LED Sequence Figure 2-5 shows the positions of the LEDs on the 3F00-01 front panel. 3F00-01 SN FDDI MIC A OPTICAL BYPASS FDDI MIC B THRU RX PROC RING A RING B OFFLINE MULTI-MODE MULTI-MODE Figure 2-5 TX PWR WRAP 3F00-01 LEDs The LED power-up sequence for the 3F00-01 is as follows: 1.

Chapter 2: Connecting to the Network 2.3 KEYING OF MEDIA INTERFACE CONNECTORS Optical fiber connections are made using a Media Interface Connector (MIC).
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.
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. 2.4 CONNECTING THE 3F00-01 OR 3F55-01 TO THE NETWORK Caution: Power-off the ATX before connecting the 3F00-01 or 3F55-01 to the network.
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. Note: Remember, when DASs are connected on an FDDI ring, A ports (MIC A) must be connected to B Ports (MIC B), and B ports must be connected to A ports. 1.
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. 1. Attach the MIC A plug on the end of the first cable assembly to the receptacle labeled “FDDI MIC A” on the module front panel (Figure 2-8). 2.
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. It also contains MIC A and MIC B receptacles for connecting to the ring. Figure 2-9 shows the OBS connectors.
Chapter 2: Connecting to the Network 4. Attach the MIC B plug on the other end of the first cable to the MIC B receptacle on the first DAS. 5. Attach the MIC B plug on the end of the second cable assembly to the MIC B receptacle on the OBS (Figure 2-9). 6. Attach the MIC A plug on the other end of the second cable to the MIC A receptacle on the second DAS. 7. Check the LEDs. In this configuration the RING A RX, TX and THRU LEDs will be on.
CHAPTER 3 CONFIGURING THE 3F00-01 AND 3F55-01 You can configure your 3F00-01 and 3F55-01 using the following tools: • Local Console Manager (LCM), an application that allows you to monitor, manage, and configure your ATX through an out-of-band RS-232 connection.

Chapter 4: Monitoring and Managing the 3F00-01 and 3F55-01 • Enabled/Disabled – enabled if it is operational, or disabled if you used the disable command to disable it. If the port is enabled but not operational, its status will be broken. (A port could be broken if it is so badly misconfigured as to be unusable, or if the port cannot connect to the logical ring). • Spanning Tree – the port’s Spanning Tree state.
Chapter 4: Monitoring and Managing the 3F00-01 and 3F55-01 - Small Buffers – number of buffers currently assigned to the port (see RX_Q Overflows below). - RX_Q Overflows – number of packets dropped by the port due to a lack of buffers. After a reboot, the ATX tries to automatically re-allocate the Small Buffers among the ports so the total number of RX_Q Overflows is minimized.

Chapter 5: Diagnostics and Troubleshooting 5.2 OPERATIONAL DIAGNOSTICS Operational diagnostics for the 3F00-01/3F55-01 consist of built-in local and remote loopback tests. These tests can be initialized by your network management system, and the test results are reported back to the NMS. When in local loopback, a port is disconnected from its network. The ATX generates loopback packets for the port, and the port loops the packets back without sending them into its network.
Chapter 5: Diagnostics and Troubleshooting 5.2.2 Connectivity Problems 1. Check for LED abnormalities, such as WRAP LEDs on, or THRU LEDs or RX, TX LEDs not lit. (LED behavior during normal operation is explained earlier in this chapter.) 2. Check the status of the 3F00-01/3F55-01 port using LCM. The status can be either: • Wrapped – indicates breaks in the ring • Twisted – indicates that the two FDDI cables have been incorrectly connected 3. Check that the MICs are keyed correctly.
CHAPTER 6 ADDING/SWAPPING MODULES Once you have received your ATX, you may want to add a new module to expand your network bandwidth, replace a module with a module of a different type, or swap a module with another module of the same type . If you are: • Adding a 3F00-01 or 3F55-01 to a previously vacant slot or to a slot that had a different type of module (which includes replacing a 3F00-01 with a 3F55-01), see Adding a 3F00-01 or 3F55-01 below, for instructions.
Chapter 6: Adding/Swapping Modules 1. Make sure the ATX is powered off. 2. Remove the network connections from the module you are going to replace. 3. Loosen the screws at each end of the front panel of the interface module you are going to replace. 4. Remove the installed interface module by pulling gently, but firmly, on the ears at the ends of the module’s front panel. 5. Gently slide the switch module into the plastic guides in the module slot until it is completely inserted.
Chapter 6: Adding/Swapping Modules 5. Remove the installed module by pulling gently, but firmly, on the ears at the ends of the module’s front panel. 6. Gently slide the new module into the plastic guides in the module slot until it’s completely inserted. Push the module firmly into place, as far as it will go, to fully engage the connectors at the back of the module with the backplane at the rear of the ATX chassis. 7. Tighten the screws on each side of the module’s front panel. 8.
