Avaya Installation Guide M15-155 ATM SWITCHING MODULES FOR THE AVAYA M770 Catalog No. 130030 Rev. F. July, 2001 Chapter 1 Overview This installation guide is divided into the following main sections: • Overview: A general description of the Avaya M15-155F, M15-155SF and M15 155MS modules, including interfaces, LED indicators, a front panel illustration and a list of hardware features. • Installation: Step-by-step instructions for installing the M15-155 in an Avaya M770 ATM switch. • Troubleshooting: Suggested solutions for commonly encountered problems. • Appendix: Port connector pin assignments. Note: The Command Line Interface (CLI) software setup and control of the Avaya M770 ATM modules is described in the Avaya M770 ATM Switch User’s Guide. Description There are three 15-port ATM OC-3 modules for the Avaya M770 Multifunction switch: the M15-155F Multi-Mode Fiber (MMF) module, the M15-155SF SingleMode Fiber (SMF) module and the combined M15-155MS module which has 2 Single-Mode and 13 Multi-Mode ports. They provide connection for OC-3 ATM servers and end stations and act as a backbone between switches. The M15-155 modules and other M770 ATM switching modules comprise a fully functional ATM switch within the Avaya M770 Multifunction chassis. There is no need for a central ATM switching or processing module. The only central module required is the M-SPV/M-SPX/M-SPS Supervisor module (one or two for redundancy) for clock generation for all the Avaya M770 ATM modules. The M770 ATM switch is a high-performance distributed Asynchronous Transfer Mode (ATM) switch that is designed for building campus backbone applications, high-performance centralized servers, and power-user environments. Its advanced architecture can support very high traffic loads with no data loss or breaks in communication. The M770 ATM Switch also implements LAN Emulation (LANE) components. LANE enables legacy LAN applications to use a transparent ATM transport medium. In this way, end-stations on existing LANs can communicate with ATM end-stations. The Avaya M770 supports a range of ATM switching modules that enable you to customize the switch for different applications in your network. The M770 ATM switch is designed as a software-upgradeable product, so that you can expand the functionality of the switch by downloading new software. The M15-155 is manageable with CajunView™, Avaya’s family of SNMP network management systems, or any other SNMP-based management system.

Entering Boot Loader Program To enter Boot Loader Mode, press both the 34 pushbuttons simultaneously and hold until the OPR LED switches OFF (about 4 seconds). 4 M15-155 Installation Guide Chapter 2 Installation Installation Overview There are several stages involved in the installation of the M15-155: • Module Installation: Inserting the module in the Avaya M770 chassis and connecting cables to the module’s ports for connection to other equipment such as a switch or station. • Command Line Interface (CLI): Connecting a terminal to the local console to access the CLI and configuring all parameters. The CLI commands and the explanation of how to configure the switch are described in the Avaya M770 ATM Switch User’s Guide. Caution: The M15-155 contains components sensitive to electrostatic discharge. To prevent ESD damage, always hold the card by its sides only, and do not touch the circuit board components unless instructed to do so. Before handling the module or inserting it in the hub, touch the chassis of the hub to discharge any electrostatic charge on your body. Note: The recommended Avaya M770 configuration is two M-PS800 units, plus a third unit for redundancy. Such a configuration supports any number of ATM, DomainX and Avaya M400 Gate Switch Modules in the chassis. • One M-PS800 supports 7 M15-155 modules. • One M-PS500 supports 4 M15-155 modules. • Three M-PS500 support up to 12 M15-155 modules with no power supply redundancy. Laser Safety The M15-155SF Single-Mode transceiver module and the two M15-155MS SingleMode transceiver ports are Class 1 Laser devices. They comply with IEC 825-1 and Food and Drug Administration (FDA) 21 CFR 1040.10 and 1040.11. The transceivers must be operated under recommended operating conditions. CLASS 1 LASER PRODUCT M15-155 Installation Guide 5 Chapter 2 Installation Laser Classification Note: Class 1 lasers are inherently safe under reasonably foreseeable conditions of operation. Caution: The use of optical instruments with this product will increase eye hazard. Usage Restriction The optical ports of the module must be terminated with an optical connector or a dust plug when not in use. Laser Data • Wavelength: 1300 nm • Single-Mode Ports: Transmit power (M15-155SF, M15-155MS SM ports, 9 µm SMF): Minimum -15 dbm, Maximum -8 dbm Receive power (M15-155SF, M15-155MS SM ports, 9 µm SMF): Minimum -30 dbm, Maximum -8 dbm • Multi-Mode Ports: Transmit power (M15-155F, M15-155MS MM ports, 62.5 µm and 50 µm MMF): Minimum -20 dbm, Maximum -14 dbm Receive power (M15-155F, M15-155MS MM ports, 62.5 µm and 50 µm MMF): Minimum -31 dbm, Maximum -14 dbm Installing the Module The M15-155 modules occupy one slot in the Avaya M770 chassis and can be inserted into any available position. The Avaya M770 chassis ATM Backplane is available in two versions: a single-domain or a dual domain ATM Backplane. If you have the dual-domain version note that slots 1 to 7 and slots 8 to 14 in the chassis function as two separate, unconnected ATM switching domains. Therefore, if you intend to use several ATM modules as a single switch they should be on the same side of the Avaya M770 chassis. The M15-155 can be installed or removed while power is on. To install the M15-155: 6 • Hold the module (shaped like an upside down L) using both hands. The colored module name panel and LEDs should be on top (see Figure 3). • Fold out the plastic handles on the top and bottom of the front panel. M15-155 Installation Guide Chapter 2 • Installation While holding the module by its handles, place it onto the top and bottom guide rails in the chassis and gently slide it in by pressing in the middle of the module. The module should slide in smoothly. Caution: Ensure that the metal edges of the card (not the PCB) are aligned with the guide rails. Align the bottom edge first and then the top edge since the module slots in the bottom rail before the top rail. • Plug in the module by pressing firmly on the mid-section of the front panel. Fold down the handles and secure the module using the two screws at the top and bottom of the front panel. Do not over-tighten the screws. Note: Even though the modules are hot-swappable, a self initialization period is required when inserting them into the chassis. Allow about 30 seconds initialization time after inserting the module for self testing and decompression of code from Flash to RAM. If the local LECS is in Resilient mode then it will take 2 minutes for the LANE to function (see the Avaya M770 ATM Switch User’s Guide).

If there are several M15-155 modules, one module will be elected as the Master Agent, and the NMA LED on that module will also light ON. For a detailed explanation of the Master Agent please refer to the Avaya M770 ATM Switch User’s Guide. Connecting the Console Terminal Initial software configuration of the M15-155 is done using a console terminal connected to the Console connector on the front panel of the module. See the Appendix for connector pin assignments. To connect the M15-155 to a console terminal: 1. Turn on the VT100 terminal (or PC terminal emulator in VT100 or VT52 mode) and set its communication parameters to: Baud rate: 9600 bps Start bit: 1 Data bits: 8 Stop bit: 1 Parity: None Refer to your terminal’s user manual for instructions on how to set these parameters. 2. Insert the RJ-45 connector of the cable into the Console port on the M15-155 front panel (see Table 3 for connector pinout). 3. Insert the other end of the cable into the terminal’s RS-232 port. 4. Press <Enter> to verify that the cabling process was successful. The system prompt appears (M770sXX:/>). 5. The CLI commands and the explanation of how to configure the switch are described in the Avaya M770 ATM Switch User’s Guide. 8 M15-155 Installation Guide Chapter 3 Troubleshooting Use the table below to troubleshoot common problems.
