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 transcei vers 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

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

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.

Overview

1.3 OVERVIEW

The following two subsections provide brief overviews of the 9A656-04 and the 9A686-04
respectively:

9A656-04

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. Enterasys 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.

9A686-04

The 9A686-04 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 9A686-04 to
provide front panel connectivity to the network. Enterasys Systems ANIMs can support up to
622 Mbps of bandwidth per port. The 9A686-04 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 9A686-04
module.

Chapter 1: Introduction

1.3.1 Distributed Management Framework

Through its distributed management framework, the 9A686-04 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.

“

NOTE

Throughout this manual, it is important to understand that the 9A656-04/9A686-04
are part of an overall “system” which is the SmartSwitch 9500. With one or more
9A656-04/9A686-04s 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 9A656-04/9A686-04 modules installed.

1.3.2 ATM Forum Specifications

The 9A686-04 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

1.3.3 A TM Traffic T ypes

The 9A686-04 supports the following standard ATM traffic classes:

Constant Bit Rate (CBR): ATM traf fic class that is guaranteed a fixed amount of bandwidth
while the Virtual Circuit (VC) is active.

V ariable Bit Rate (VBR): ATM traffic class that v aries the amount of bandwidth used on the
VC while the VC is active, while maintaining a minimum CBR component.

Available Bit Rate (ABR): A TM 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.

1.3.5 Distributed Clocking

The 9A686-04 supports three clocking modes:

Clock Recovery Mode

This clocking mode is required when the 9A686-04 is CONNECTED to the public ATM
network. In this mode, the 9A686-04 derives its transmit clock from the incoming line clock.

Master Clock Distribution

This clocking mode is required when the 9A686-04 is PART of the public ATM network. In
this mode, one 9A686-04 installed in the SmartSwitch 9500 chassis is configured as the
master clock for all other modules attached to the CTM backplane. The 9A686-04 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 9A686-04 if the master clock signal is lost, or in the
absence of any external clock source. In this mode each 9A686-04 installed in the chassis acts
as its own clock source.

9A656-04/9A686-04 Configuration Guide Page 1-5

Chapter 1: Introduction

1.3.6 ATM Adaptation Layer (AAL) Support

The 9A686-04 support 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 9A686-04 use a geographic interface numbering scheme that allows for easy identiÞca­tion of each front panel and backplane interface of each 9A686-04 installed in the Smart­Switch 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 9A686-04 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 9A686-04 with 12 front panel interfaces. Refer to Table 1-1
for a breakdown of the interface numbering scheme.

Table 1-1 Interface (Port) Numbering Example

ANIM # Interface # Slot 1 Slot 3 Slot 7 Slot 11 Slot 14

1 1 10101 30101 70101 110101 140101
1 2 10102 30102 70102 110102 140102
1 3 10103 30103 70103 110103 140103
2 1 10201 30201 70201 110201 140201
2 2 10202 30202 70202 110202 140202
2 3 10203 30203 70203 110203 140203
3 1 10301 30301 70301 110301 140301
3 2 10302 30302 70302 110302 140302
3 3 10303 30303 70303 110303 140303
4 1 10401 30401 70401 110401 140401
4 2 10402 30402 70402 110402 140402
4 3 10403 30403 70403 110403 140403

Page 1-6 9A656-04/9A686-04 Configuration Guide

Default Settings Upon First Initialization

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 9A686-04 is installed
in slot 1. The CTM ANIM is number 14, and it is port 2 of that CTM ANIM that has the
connection.

NOTE

The CTM ANIMs have two ports.

1.5 DEFAULT SETTINGS UPON FIRST INITIALIZATION

The 9A686-04, 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 9A686-04 with
plug-and-play capabilities.

1.5.1 9A686-04 Initialization Steps

The 9A686-04 performs the following procedures when they are first inserted into a powered
up SmartSwitch 9500 chassis.

1. The 9A686-04 assigns itself an ATM address. Figure 1-1 provides an example of a default

ATM address.

Base Mac Address/ESI

Figure 1-1 Default ATM Address Breakdown

Selector Byte

Chapter 1: Introduction

The 9A686-04 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 9A686-04 will assign itself a default PNNI level of 72. This
ensures that multiple 9A686-04s 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 9A686-04 activates ILMI 4.0, which allows auto configuration. This makes the

9A686-04 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 9A686-04 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 9A686-04 attempts to detect LANE services. It will continue to perform this task

every ten seconds until it receives a response.

b. The 9A686-04 attempts to establish a connection with the well-known LAN Emulation

Configuration Server (LECS).

c. Once a connection is established with the LECS, the 9A686-04 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 9A686-04s 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 9A686-04 begins switching traffic. Connections and their bandwidth requirements are

accepted on a first come, first served basis.

Default Settings Upon First Initialization

1.5.2 Additional Default Settings

The 9A686-04 also has the following additional default settings upon first initialization.

• A maximum of 128 k connections are allowed.

• Bandwidth is given to any requested connection on a first come, first served basis (i.e., no

Quality of Service (QoS) is given precedence to any particular request).

• ILMI sets the minimum and maximum VCI and VPI values for SVCs, and PVCs or SVPCs,

to the settings shown in Table 1-2. With this default setting, the SmartSwitch 9500 is an
SVC only switch. Chapter 3 provides information on how to reserve VPI/VCI ranges for
PVCs. Table 1-3 provides the total available ranges for all VCI and VPIs.

Table 1-2 Default Minimum and Maximum VCI and VPI Values for SVCs and VPCs

Minimum VCI for SVCs 33
Maximum VPI for SVCs 4095
Maximum VPI for VPCs 4095

Table 1-3 Minimum and Maximum VCI and VPI Ranges

Type Minimum V alue Maximum Value

VCI for SVCs 33 16k
Maximum VPI for SVCs 0 4095
Maximum VPI for VPCs 0 4095

• The 9A686-04 is set to be in Clock Recovery Mode, which means that all clocking will be

recovered from the received signals.

Chapter 1: Introduction

1.6 CONFIGURABLE OPTIONS

The 9A686-04 functions as a plug-and-play device, with minimal setup required by the user,
however, the module also provides a high degree of customization. The following sections
provide brief descriptions of the functions that may be customized depending on the
requirements of the network administrator, and the ATM network.

1.6.1 Configurable Options at the System (Chassis) Level

As described earlier, the SmartSwitch 9500 chassis with at least one 9A686-04 installed,
allows the chassis to be assigned IP addresses for management purposes. With the
SmartSwitch 9500 chassis operating in this way, many new configurable parameters for the
chassis become available. These options are described as follows:

System IP Address

The system IP address allows the chassis to be managed out-of-band via a connection to the
COM2 port of the Environmental Module, via the EPIM installed in the Environmental
Module (SMB-10), and in-band through the LEC created upon module initialization.

SNMP T raps

The SmartSwitch 9500 chassis is SNMP compliant and is capable of being configured to send
messages to multiple Network Management Stations to alert users of status changes.

SNMP Community Names

Community names act as passwords to Local/Remote Management and provide security
access to the SmartSwitch 9500 chassis. Access to the chassis and module management
screens is controlled by enacting any of three different levels of security authorization
(read-only, read-write, and super-user).

Chassis Date and Time

This feature supports assigning values that the SmartSwitch 9500 chassis recognizes as the
current date and time. When the chassis date and time are modified and saved, all 9A686-04
modules installed in the chassis are set to these values.

Chassis Power Supply Information (Read-only Screen)

Local Management provides access to the Chassis Power screen. This screen contains current
information on the status of all power supplies installed in the SmartSwitch 9500 chassis.

Page 1-10 9A656-04/9A686-04 Configuration Guide

Configurable Options

Environmental Module Configuration

Local Management provides access to the Environmental Module screen. This screen allows
the user to view current operating conditions of the Environmental Module (EM), configure
the COM ports of the EM, and download a new firmware image for the EM to FLASH
memory.

ILMI Configuration

The ILMI Configuration screen allows the user to set the minimum value for Virtual Channel
identifiers (VCIs) for front panel and backplane Switched Virtual Connections (SVCs), the
maximum value for Virtual Path Identifiers (VPIs) for SVCs, and the maximum value for
Virtual Path Identifiers (VPIs) for Switched Virtual Path Connections (SVPCs) for the entire
system (SmartSwitch 9500 chassis).

PNNI Configuration

The PNNI Configuration screen allows the user to set the NSAP prefix and PNNI level of the
SmartSwitch 9500 chassis. When these settings are saved, each 9A686-04 installed in the
chassis share the same NSAP prefix, and the same PNNI level.

ATM Diagnostics

The SmartSwitch 9500 chassis can be set to run ATM diagnostics when power is c ycled or the
modules are reset. All major hardware subsystems of the system are tested during the power
up diagnostics.

Chapter 1: Introduction

1.7 LOCAL MANAGEMENT SCREEN ELEMENTS

This section describes the conventions that are used when describing the Local Management
screens used to configure the SmartSwitch 9500 chassis and the 9A686-04 in later chapters of
this guide.

There are five types of screens used in Local Management: password, menu, configuration,
status, and warning screens. Each type of screen can consist of one to five basic elements, or
fields. Figure 1-2 shows an example of the fields in a screen. A description of each field
follows the figure.

NOTE

The following definitions apply to most Cabletron Systems Local Management
screens. Exceptions to these definitions may occur in the Local Management
screens of some Cabletron Systems devices.

Figure 1-2 Example of a Local Management Screen

The following list explains each of the Local Management fields:

Event Message Field

This field briefly displays messages that indicate if a Local Management procedure was
executed correctly or incorrectly, that changes were saved or not saved to Non-Volatile
Random Access Memory (NVRAM), or that a user did not have access privileges to an
application.

Page 1-12 9A656-04/9A686-04 Configuration Guide

Local Management Screen Elements

NOTE

Only the password, configuration and status screens have event message fields.

Table 1-4 describes the most common event messages. Event messages related to specific

Local Management applications are described with those applications throughout this manual.

Display Fields

Display fields cannot be edited. These fields may display information that never changes, or
information that may change as a result of Local Management operations, user selections and
configurations, or network monitoring information. In the screens shown in this guide, the
characters in the display fields are in plain type (not bold). In the field description, the field is
identified as being “read-only”.

Input Fields

Input Fields require the entry of keyboard characters. IP addresses, subnet mask, default
gateway and device time are examples of input fields. In the screens shown in this guide, the
characters in the input fields are in bold type. In the field description, the field is identified as
being “modifiable”.

Selection/Toggle Fields

Selection/Toggle fields provide a series of possible values. Only applicable values appear in a
selection field. In the screens shown in this guide, the selection displays within brackets and in
bold type. In the field description, the field is identified as being either “selectable” when there
are more than two possible values, or “toggle” when there are only two possible values.

Command Fields

Command fields are located at the bottom of Local Management screens. Command fields are
used to exit Local Management screens, save Local Management entries, or navigate to
another display of the same screen. In the screens shown in this guide, the characters in this
field are all upper case and in bold type. In the field description, the field is identified as being
a “command” field.

1.7.1 Local Management Keyboard Conventions

All key names appear in this manual as capital letters. For example, the Enter key appears as
ENTER and the Backspace key appears as BACKSPACE. Table 1-5 explains the keyboard
conventions used in this manual as well as the key functions.

Table 1-5 Keyboard Conventions

Key Function

ENTER Key and RETURN Key These are selection keys that perform the same Local

Management function. For example, “Press ENTER”
means that you can press either ENTER or RETURN,
unless this manual specifically instructs you otherwise.

SPACE Bar and BACKSPACE Key These keys cycle through selections in some Local

Management fields. Use the SPACE bar to cycle
forward through selections and use BACKSPACE to
cycle backward through selections.

Arrow Keys These are navigation keys. Use the UP-ARROW,

DOWN-ARROW, LEFT-ARROW, and RIGHT-ARROW
keys to move the screen cursor. For example, “Use the
arrow keys” means to press whichever arrow key
moves the cursor to the desired field on the Local
Management screen.
