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.

The 2E4X-27R is a tabletop unit that can be installed in a standard 19-inch rack using the supplied rack mounting hardware.

The 2E4X-27R 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.

2E48-27R/2E49-27R User’s Guide 1-3

Chapter 1:

Introduction

1.3.1 Connectivity

The 2E48-27R connects to Ethernet networks or workstations through 24 ST ﬁber optic ports on the front panel. These ports support multimode ﬁber optic cables at lengths up to 2 kilometers. The ports are IEEE 802.3 10BASE-F compliant.

The 2E49-27R connects to Ethernet networks or workstations through 24 ST ﬁber optic ports on the front panel. These ports support single mode ﬁber optic cables at lengths up to 5 kilometers. The ports are FOIRL compliant.

All of the devices have tw o front panel slots (ports 25 and 26) 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

Each switched Ethernet port supports full wire-speed Ethernet communications and can be conﬁgured to operate in Full Duplex Switched Ethernet (FDSE) mode. FDSE allows each port to provide a dedicated 20 Mbps bandwidth for ﬁle server or high-end workstation connections. The optional Fast Ethernet ports provide up to 200 Mbps of bandwidth.

1.3.3 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.

SmartTrunk User’s Guide

1.3.4 Runtime IP Address Discovery

This feature enables the 2E4X-27R 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 2E4X-27R is connected to the network and powered up, Runtime IP Address Discovery (RAD) checks the 2E4X-27R for an IP address. If one has not yet been assigned (2E4X-27R IP address set to

0.0.0.0), RAD checks to see if any of the 2E4X-27R 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 or RARP server on the network.

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 or RARP server, or an IP address is entered using Local Management.

1.3.5 Management

Management of the 2E4X-27R is accomplished using SNMP compliant management tools for in-band 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. Local Management can also be accessed through a Telnet connection to the RJ45 COM port.

Local Management provides the ability to manage the 2E4X-27R and any of the optional Fast Ethernet Interface Modules installed in ports 25 and 26 and the optional High Speed Interface Module (HSIM).

The user’s guide for the HSIM pro vides detailed information about Local Management for the HSIM.

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