SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

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

FPIM-07 FDDI PORT INTERFACE MODULES, AND APIM-29 ATM

PORT INTERFACE MODULE 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 103 W m2 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.

2E43-51 Overview

1.3 2E43-51 OVERVIEW

The 2E43-51 (Figure 1-1) is a repeater/switch device that provides four Ethernet networks (MicroLANs ENET 1 through 4), each consisting of 12 repeater ports that share a bandwidth of 10 Mbps. Each Ethernet network supports 802.1D switching (bridging), and Cabletron Systems SecureFast Switching Virtual Network technology.

The 2E43-51 also has two slots (5 and 6) for optional 10/100 Fast Ethernet Interface Modules, and another slot for an optional High Speed Interface Module (HSIM).

The device can switch each Ethernet network (ENET 1 through ENET 4) to one another, to the optional interface modules in slots 5 and 6, and to the HSIM slot. The optional Fast Ethernet Interface Modules provide uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet networks. The HSIMs provide additional connectivity to various networking technologies such as Asynchronous Transfer Mode (ATM), Fiber Distributed Data Interface (FDDI), and Wide Area Network (WAN).

The 2E43-51 may be used as a tabletop unit or can be installed in a standard 19-inch rack using the supplied rack mounting hardware.

The 2E43-51 device has one universal ac power supply with automatic voltage sensing that allows operation using 100–125 or 200–240 Vac, 50/60 Hz.

2E43-51/2E43-51R User’s Guide 1-3

Chapter 1:

The 2E43-51R has two power supplies. The power supplies load share 50% (+/-5%) of the power required by the device. If one power supply fails, the remaining power supply assumes the entire load of the device without interruption to network trafﬁc. Each power supply module supports its own ac input connection, which allows the user to connect each power supply to a different ac power circuit.

Introduction

1.3.1 Connectivity

The 2E43-51 connects to Ethernet networks or workstations through four 50-pin RJ21 connectors. Each connector serves as a 12-port Ethernet 10 Mbps MicroLAN.

Both of the devices have two front panel slots (ports 5 and 6) for optional Fast Ethernet Interface Modules to support an uplink to 100 Mbps Fast Ethernet backbones or a high speed connection to a local server. There is also space for an optional HSIM to provide additional connectivity to various networking technologies.

1.3.2 Full Duplex Switched Ethernet

The optional Fast Ethernet Interface Modules for the 2E43-51 can be conﬁgured to operate in Full Duplex Switched Ethernet mode, which provides 200 Mbps of bandwidth.

1.3.3 Auto-Negotiation

The repeater ports and Fast Ethernet Interface Modules can auto-negotiate the type of connection required to provide a link to another device. During Auto-Negotiation, two devices automatically exchange information “telling” each other what their operating capabilities are. The Auto-Negotiation feature targets the maximum capabilities that can be reached between the two devices. For example, an FE-100TX Fast Ethernet Interface Module in a 2E43-51 can adjust to 100 Mbps when the device on the other end of the connection can also adjust to 100 Mbps. If the device on the other end of the connection can only operate at 10 Mbps, then the FE-100TX simply adjusts to 10 Mbps operation.

1-4 2E43-51/2E43-51R User’s Guide

2E43-51 Overview

When Auto-Negotiation is supported at both ends of a link, the two devices dynamically adjust to full or half duplex operation based on the maximum capability that can be reached between the two devices. If the device connected to the FE-100TX cannot auto-negotiate, the FE-100TX Fast Ethernet Interface Module operates according to the capabilities of the other device.

1.3.4 SmartTrunk

SmartTrunk, also referred to as SmartTrunking, is Cabletron Systems’ terminology for load balancing or load sharing. SmartTrunk technology provides an easy-to-implement mechanism to group, or aggregate, multiple physical links together to scale the backbone bandwidth beyond the limitations of a single link. All links are user-conﬁgurable so administrators can scale the backbone bandwidth by adding SmartTrunk links. The SmartTrunk beneﬁts are as follows:

•

All purchased bandwidth is used.

•

Distributed, resilient links increase reliability and performance.

•

Multiple technologies are supported within a single trunk for maximum ﬂexibility.

For more information about SmartTrunk, refer to the Cabletron Systems

SmartTrunk User’s Guide

1.3.5 Runtime IP Address Discovery

This feature enables the 2E43-51 to automatically accept an IP address from a Boot Strap Protocol (BootP) server on the network into NVRAM without requiring a user to enter an IP address through Local Management.

When the 2E43-51 is connected to the network and powered up, Runtime IP Address Disco very (RAD) checks the 2E43-51 for an IP address. If one has not yet been assigned (2E43-51 IP address set to 0.0.0.0), RAD checks to see if any of the 2E43-51 interfaces have a link. If so, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address from a BootP server on the network.

2E43-51/2E43-51R User’s Guide 1-5

Chapter 1:

The RAD requests start out at an interval of 1 second. The interval then doubles after every transmission until an interval of 300 seconds is reached. At this point, the interval remains at 300 seconds. The RAD requests continue until an IP address is received from a BootP server, or an IP address is entered using Local Management.

Introduction

1.3.6 Management

Management of the 2E43-51 is accomplished using SNMP compliant management tools for in-band Local Management. Out-of-band Local Management is provided through the RJ45 COM port on the front panel using a VT100 terminal or a VT100 terminal emulator. In-band remote management is possible through any SNMP compliant Network Management Software.

Local Management provides the ability to manage the 2E43-51 and any of the optional Fast Ethernet Interface Modules installed in ports 5 and 6, and the optional High Speed Interface Module (HSIM).

The associated HSIM user’s guide provides detailed information about the HSIM Local Management.

1.3.7 Switching Options

The 2E43-51 provides 802.1D switching, 802.1Q switching or SecureFast Switching Virtual Network Services between all of the front panel interfaces including Fast Ethernet Interface Modules and High Speed Interface Module (HSIM).

IEEE 802.1Q switching and SecureFast switching allow for future migration to Virtual Network technologies without requiring the replacement of existing equipment.

1.3.8 Standards Compatibility

The 2E43-51 provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 2E43-51 also supports 100BASE-TX and 100BASE-FX Fast Ethernet standards and a wide variety of industry standard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB). A full suite of Cabletron Systems Enterprise MIBs provide a wide array of statistical information to enhance troubleshooting.
