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 Single-
Mode 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.

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 Single-
Mode 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.

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.

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:
•
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.

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).

Installation
Power-on Check
When you plug in the M15-155, wait until first the CPU LED lights and then the
OPR lights steadily before commencing work. 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:
Start bit:
Data bits:
Stop bit:
Parity:
9600 bps

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.
