SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

THE FE-100F3 FAST ETHERNET INTERFACE MODULE, FPIM-05 AND FPIM-07 FDDI PORT

INTERFACE MODULES, APIM-29 AND APIM-29LR ATM PORT INTERFACE MODULES,

ANIM-29/3 , ANIM-29/3LR AND ANIM-39/2 ATM NETWORK INTERFACE MODULES USE CLASS 1

LASER TRANSCEIVERS. READ THE FOLLOWING SAFETY INFORMATION BEFORE

INSTALLING OR OPERATING THESE MODULES.

The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the need for

maintenance checks or adjustments. The output is factory set, and does not allow any user adjustment. Class 1 Laser transceivers comply with

the following safety standards:

• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).

• IEC Publication 825 (International Electrotechnical Commission).

• CENELEC EN 60825 (European Committee for Electrotechnical Standardization).

When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission limit of all three

standards. Class 1 levels of laser radiation are not considered hazardous.

SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

LASER RADIATION AND CONNECTORS

When the connector is in place, all laser radiation remains within the ﬁber. The maximum amount of radiant power exiting the ﬁber (under

normal conditions) is -12.6 dBm or 55 x 10

-6

watts.

Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum radiance

from the optical port (under worst case conditions) is

0.8 W cm

-2

or 8 x 10

3

W m

2

sr-1.

Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard.

When viewing the output optical port, power must be removed from the network adapter.

9A656-04 and 9A600 Conﬁguration Guide 1-3

Overview

1.3 OVERVIEW

The 9A656-04 is a 4.5 Gbps, single slot module for the SmartSwitch 9500 chassis. Up to four

ATM Network Interface Modules (ANIMs) of any type can be installed in the 9A656-04 to

provide front panel connectivity to the network. Cabletron Systems ANIMs can support up to

622 Mbps of bandwidth per port. The 9A656-04 switches data between the ANIMs and the

Cell Transfer Matrix (CTM) backplane in the SmartSwitch 9500 chassis. This allows for

high-speed switching of data between modules installed in the same chassis that connect to

the CTM backplane. The CTM provides a dedicated 1.6 Gbps link between each 9A656-04

module.

The 9A600 is a 5.4 Gbps, single slot module for the SmartSwitch 9500 chassis. Up to four

ATM Network Interface Modules (ANIMs) of any type can be installed in the 9A600 to

provide front panel connectivity to the network. Cabletron Systems ANIMs can support up to

622 Mbps of bandwidth per port. The 9A600 switches data between the ANIMs and the other

ATM devices to which it is connected. Unlike the 9A656-04, the 9A600 does not connect to

the CTM backplane.

1.3.1 Distributed Management Framework

Through its distributed management framework, the 9A656-04 allows all the modules in the

chassis to appear as a single entity, managed through a single IP address. The individual

modules are transparent to the network manager and management applications. A fully loaded

SmartSwitch 9500 chassis appears as a single switch, with one IP address.

1.3.2 ATM Forum Speciﬁcations

The 9A656-04 is fully compliant with the following ATM Forum speciﬁcations:

•

Intergrated Local management Interface (ILMI) 4.0 for autoconﬁguration.

•

UNI v3.0 /3.1 and v4.0 for signalling.

•

ATM Forum P-NNI 1.0 and IISP 3.0/3.1/4.0 routing speciﬁcations for establishing

connections between ATM switches.

•

LANE 1.0 for the management LAN Emulation Client.

•

TM 4.0

NOTE

“

Throughout this manual, it is important to understand that the 9A656-04 and 9A600

are part of an overall “system” which is the SmartSwitch 9500. With one or more

9A656-04 or 9A600s installed, the chassis becomes a single switch, with all boards

installed being a part of that single switch, not a separate component.

When this manual refers to the “system” it is referring to a SmartSwitch 9500

chassis with one or more 9A656-04 or 9A600 modules installed.

Chapter 1:

Introduction

1-4 9A656-04 and 9A600 Conﬁguration Guide

1.3.3 ATM Trafﬁc Types

The 9A656-04 supports the following standard ATM trafﬁc classes:

•

Constant Bit Rate (CBR): ATM trafﬁc class that is guaranteed a ﬁxed amount of bandwidth

while the Virtual Circuit (VC) is active.

•

Variable Bit Rate (VBR): ATM trafﬁc class that varies the amount of bandwidth used on the

VC while the VC is active, while maintaining a minimum CBR component.

•

Available Bit Rate (ABR): ATM trafﬁc class that allows VCs to use the greatest amount of

bandwidth available on the link at any point in time.

•

Unspeciﬁed Bit Rate (UBR): ATM trafﬁc class that does not contain any bandwidth

guarantees.

1.3.4 MIB Support

The 9A656-04 provides support for a variety of Industry Standard and Cabletron Systems

speciﬁc MIBs. Details on these MIBs are provided in later chapters of this Guide. The MIBs

supported are as follows:

•

MIB2 (RFC 1573)

•

AToM MIB (RFC 1695)

•

AToM II MIB

•

ILMI MIB

•

PNNI MIB

•

9A656-04 and 9A600 Conﬁguration Guide 1-5

Overview

1.3.5 Distributed Clocking

The 9A656-04 supports three clocking modes:

Clock Recovery Mode

This clocking mode is required when the 9A656-04 is CONNECTED to the public ATM

network. In this mode, the 9A656-04 derives its transmit clock from the incoming line clock.

Master Clock Distribution

This clocking mode is required when the 9A656-04 is PART of the public ATM network. In

this mode, one 9A656-04 installed in the SmartSwitch 9500 chassis is conﬁgured as the

master clock for all other modules attached to the CTM backplane. The 9A656-04 that is the

master clock then distributes all clocking information to all the other modules.

Local Clock Mode

This clocking mode may be used by the 9A656-04 if the master clock signal is lost, or in the

absence of any external clock source. In this mode each 9A656-04 installed in the chassis acts

as its own clock source.

1.3.6 ATM Adaptation Layer (AAL) Support

The 9A656-04 supports all ATM Adaptation Layers, (AAL 1, AAL 3/4 and AAL 5).

1.3.7 Management LAN Emulation Client

The SmartSwitch 9500 system creates a default management LEC upon ﬁrst initialization.

The LEC automatically joins the default ELAN. Although all modules in the chassis are

capable of becoming the LEC, only one LEC is active in the system at one time. This is

accomplished through a LEC election algorithm.

1.4 INTERFACE (PORT) NUMBERING

The 9A656-04 uses a geographic interface numbering scheme that allows for easy identiÞca-

tion of each front panel and backplane interface of each 9A656-04 installed in the Smart-

Switch 9500 chassis. Interface numbers are generated as follows:

Slot ##, ANIM ##, Interface ##

Table 1-1 provides an example of how the interface numbering scheme works. In this

example, there is a SmartSwitch 9500 chassis with ﬁve 9A656-04 modules installed. These

modules are installed in slots 1, 3, 7, 11 and 14. Each of these modules are equipped with 4

ANIM 21/3s. This provides each 9A656-04 with 12 front panel interfaces. Refer to Table 1-1

for a breakdown of the interface numbering scheme.

CTM interfaces may be recognized by the following CTM ANIM #:

• If the ANIM number of the interface numbering scheme is 08 through 15.

For example, if the interface number is 11402. This means that the 9A656-04 is installed

in slot 1. The CTM ANIM is number 14, and it is port 2 of that CTM ANIM that has the

connection.

4 3 10403 30403 70403 110403 140403

NOTE

The CTM ANIMs have two ports.

CTM interface numbering does not apply to the 9A600.

Default Settings Upon First Initialization

1.5 DEFAULT SETTINGS UPON FIRST INITIALIZATION

The 9A656-04, upon ﬁrst initialization, performs a series of pre-conﬁgured setup procedures.

These procedures set up a default conﬁguration of the switch that allows the device to begin

functioning in the network immediately. No setup is required by the user except the

assignment of an IP address for management purposes. This provides the 9A656-04 with

plug-and-play capabilities.

1.5.1 9A656-04 Initialization Steps

The 9A656-04 performs the following procedures when it is ﬁrst inserted into a powered up

SmartSwitch 9500 chassis.

1. The 9A656-04 assigns itself an ATM address. Figure 1-1 provides an example of a default

ATM address.

Figure 1-1 Default ATM Address Breakdown

The 9A656-04 will always assign itself the default NSAP prefix shown in Figure 1-1. The

section of the address following the NSAP prefix will be the last 4 bytes of the base MAC

address of the module. The End System Identifier (ESI) will always be the base MAC

address of the module. The 9A656-04 will assign itself a default PNNI level of 72. This

ensures that multiple 9A656-04s installed in the same chassis will automatically belong to

the same peer group (via the default NSAP prefix and level) and will not produce multiple

Nodes with the same Node ID (via the unique base MAC address).

2. The 9A656-04 activates ILMI 4.0, which allows auto configuration. This makes the

9A656-04 capable of using any version of ILMI (3.0, 3.1, or 4.0) that a User, other ATM

switch, or ATM Access device may be using when communicating with the system. Each

interface will become a UNI, IISP or PNNI connection automatically.

3. The 9A656-04 runs the LEC election algorithm. If this module is elected it creates a LAN

Emulation Client (LEC) that is used for management purposes. This LEC then goes

through the following substeps:

a. The 9A656-04 attempts to detect LANE services. It will continue to perform this task

every ten seconds until it receives a response.

b. The 9A656-04 attempts to establish a connection with the well-known LAN Emulation

Configuration Server (LECS).

c. Once a connection is established with the LECS, the 9A656-04 joins the default ELAN.

If management functions are performed via a different ELAN, Local Management

allows the user to specify the ELAN to which the LEC will belong.

4. If there are multiple 9A656-04s in the chassis, an election process occurs where one of the

modules is elected to handle all management requests to the SmartSwitch 9500 chassis.

5. The 9A656-04 begins switching traffic. Connections and their bandwidth requirements are

accepted on a first come, first served basis.
