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.

2M46-04R Overview

The 2M46-04R is a tabletop unit that can be installed in a standard 19-inch rack using the supplied rack mounting hardware.

The 2M46-04R has two ac power supplies. The po wer 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.

The 2M46-04RDC operates from two dc voltage power sources. 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 dc input connection, which allows the user to connect each power supply to a different dc power source.

1.3.1 Connectivity

The 2M46-04R has two front panel slots (ports 1 and 2) 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 are also two HSIM slots for optional HSIMs to provide additional connectivity to various networking technologies.

1.3.2 Full Duplex Switched Ethernet

The optional Fast Ethernet Interface Modules can be conﬁgured to operate in Full Duplex Switched Ethernet (FDSE) mode which provides up to 200 Mbps of throughput per interface.

2M46-04R/2M46-04RDC User’s Guide 1-3

Chapter 1:

Introduction

1.3.3 Auto-Negotiation

The optional FE-100TX Fast Ethernet Interface Module 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, a 2M46-04R FE-100TX Fast Ethernet Interface Module adjusts 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 2M46-04R Fast Ethernet Interface Module simply adjusts to 10 Mbps.

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 2M46-04R cannot auto-negotiate, the 2M46-04R 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

2M46-04R Overview

1.3.5 Runtime IP Address Discovery

This feature enables the 2M46-04R to automatically accept an IP address from a BootP server on the network into NVRAM without requiring the user to enter an IP address through Local Management.

When the 2M46-04R is connected to the network and powered up, Runtime IP Address Discovery (RAD) checks the 2M46-04R for an IP address. If one has not yet been assigned, RAD checks to see if any of the 2M46-04R 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.

The RAD requests start out at an interval of 1 second, then the interval 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.

1.3.6 Management

Management of the 2M46-04R is accomplished using Local Management tools or remote SNMP management stations. Local Management is accessible through the RS232 COM port on the front panel using a local VT100 terminal, or a remote VT100 terminal via a modem connection, and in-band via a Telnet connection. In-band remote management is possible through any SNMP compliant Network Management Software.

Local Management provides the ability to manage the 2M46-04R and any of the optional Fast Ethernet Interface Modules installed in ports 1 and 2 and the optional High Speed Interface Modules (HSIMs).

The associated High Speed Interface Module user’s guide provides detailed information about Local Management of the HSIM.

Information about how to access and use Local Management is contained in Chapter 5.
