Safety Notice

Safety Information

CLASS 1 LASERTRANSCEIVERS

The 9A129-01 is a Class 1 Laser Product

The 9A129-01 uses Class 1 Laser transceivers. Read the following safety

information before installing or operating these adapters.

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.

CLASS 1 LASERTRANSCEIVERS

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

W m

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.

Introduction

The 9A128-01 and 9A129-01 ATM Access Modules (shown in Figure 1-1) provide

an ATM Uplink that allows connecting an external ATM network to the

MMAC-Plus.

The 9A128-01 and 9A129-01 are used to connect an external ATM network or

workstation to one of the two FNB networks, FNB-1 or FNB-2, on the

MMAC-Plus FNB backplane. External connections are made via a front panel, 155

Mbps SONET ATM interface.

The 9A128-01 and 9A129-01 are fully compatible with all ATM Forum

speciﬁcations, including UNI 3.0, ILMI and LAN Emulation. The 9A128-01 and

9A129-01 act as a ATM Forum LAN Emulation Client, allowing Ethernet, Token

Ring and FDDI users to access an ATM backbone.

Features

Processor

The 9A128-01 and 9A129-01 are equipped with an advanced Intel i960

microprocessor. This microprocessor provides a platform for all management

functions within a scalable RISC-based architecture.

System Management

The 9A128-01 and 9A129-01 interface to the two System Management Buses

(SMB-1 and SMB-10) for intermodule management. Management features include

the following:

• Module Insert/Bypass Control

• MAC Placement

• Station Management (SMT) Statistics

• Bridging Statistics (for all interfaces) including

- Frames Filtered

- Frames Forwarded

- All STA Parameters

Introduction

Hardware Bridging Logic

Hardware frame ﬁlter/forward logic increases the bridging performance of the

9A128-01 and 9A129-01, allowing the modules to achieve higher throughputs (up

to 20,000 packets per second).

SpanningTree Algorithm

The 9A128-01 and 9A129-01 support both IEEE 802.1d and DEC Spanning Tree

Algorithm (STA) protocols.

Connectivity

For ATM, the 9A128-01 uses a 155 Mbps SONET OC3 Multimode Fiber front

panel interface and the 9A129-01 uses a single mode ﬁber interface. These have a

SC type connector. In addition, the 9A128-01 and 9A129-01 have two physical

FDDI interfaces (FNB-1, and FNB-2) and allows bridging one of these to the front

panel interface.

LANVIEW LEDs

The 9A128-01 and 9A129-01 use LANVIEW: the Cabletron Systems built-in visual

diagnostic and status monitoring system. With LANVIEW LEDs, you can quickly

identify the device, port, and physical layer status at a glance.

Hot Swapping

The 9A128-01 and 9A129-01 can be installed or removed from the chassis while

the MMAC-Plus is powered up without affecting the operation of the rest of the

network.
