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.

Chapter 1:

Introduction

1.4 2E4X-27 OVERVIEW

The 2E4X-27 is a 27-port high-speed network switching device that supports traditional switching (bridging) and Cabletron Systems SecureFast Switching Virtual Network technology. Ports 25 and 26 support optional Fast Ethernet Interface Modules and can provide uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet networks. Port 27 supports an optional High Speed Interface Module (HSIM) that provides additional connectivity to various networking technologies such as Asynchronous Transfer Mode (ATM) and Fiber Distribution Data Interface (FDDI).

The 2E4X-27 is used to connect individual high-bandwidth user devices, such as workstations, and provides a central switching point for multiple Ethernet segments built using devices such as Cabletron Systems HubSTACK or other third party stackable devices.

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

The 2E42-27 and 2E43-27

have one universal ac power supply with automatic voltage sensing that allows operation using 100–125 or 200–240 Vac, 50/60 Hz.

The 2E42-27R and 2E43-27R have 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.

1.4.1 Connectivity

Connectivity for ports 1 through 24 is different for the 2E42-27/2E42-27R and the 2E43-27/2E43-27R.

The 2E42-27/2E42-27R connects to Ethernet networks or workstations through 24 RJ45 ports on the front panel. These ports support Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP) cables at lengths up to 100 meters. The ports are IEEE 802.3 10BASE-T compliant.

The 2E43-27/2E43-27R connects to Ethernet networks or workstations through two 50-pin RJ21 connectors. Each connector is wired for 12 ports.

1-4 2E42-27/2E42-27R/2E43-27/2E43-27R User’s Guide

2E4X-27 Overview

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.

1.4.2 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 Fast Ethernet ports provide up to 200 Mbps of bandwidth.

1.4.3 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.

For more information about SmartTrunk, refer to the Cabletron Systems

Introduction

1.4.4 Runtime IP Address Discovery

This feature enables the 2E42-27 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 2E42-27 is connected to the network and powered up, Runtime IP Address Disco very (RAD) checks the 2E42-27 for an IP address. If one has not yet been assigned (2E42-27 IP address set to 0.0.0.0), RAD checks to see if any of the 2E42-27 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. 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.

1.4.5 Management

Management of the 2E4X-27 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. In-band remote management is possible through any SNMP compliant Network Management Software.

Local Management provides the ability to manage the 2E4X-27 and any of the optional Fast Ethernet Interface Modules installed in ports 15 and 16 and the optional High Speed Interface Module (HSIM).

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.

3.4.2 Connecting a UTP Segment to the FE-100TX

NOTE

An FE-100TX installed in port slot 25 and/or 26 has an internal crossover switch. When connecting a workstation, use a straight-through cable and set the Fast Ethernet Interface Module crossover switch shown in

Figure 3-10 to the crossed over position marked with X.

2E42-27/2E42-27R/2E43-27/2E43-27R User’s Guide 3-13

To ensure proper operation, use only Category 5 Unshielded Twisted Pair (UTP) cabling that has an impedance between 85 and 111 ohms.

Chapter 3: Installation

When connecting networking devices, such as another bridge, repeater , or router, use a straight-through cable and set the Fast Ethernet Interface Module crossover switch shown in Figure 3-10 to the not crossed over position, marked with =.

A schematic of a crossover cable is shown in Figure 3-7. If the wires do not cross over, use the switch on the FE-100TX to internally cross over the RJ45 port. Figure 3-10 shows how to properly set the FE-100TX crossover switch.

3.4.3 Connecting a Fiber Optic Segment to the

FE-100FX and FE-100F3

The FE-100FX and FE-100F3 have SC style network ports (see

Figure 3-11). Cabletron Systems supplies ﬁber optic cable that uses SC

style connectors, which are keyed to ensure proper crossover of the transmit and receive ﬁbers.

NOTES

Fiber Optic Network Connection

An odd number of crossovers (preferably one) must be maintained between devices so that the transmit port of one device is connected to the receive port of the other device and vice versa.

If the ﬁber optic cable being used has SC style connectors that do not resemble MIC style connectors, or has SC connectors on one end and a different type on the other, such as ST connectors, ensure that the proper crossing over occurs.

1. Remove the protective plastic covers from the fiber optic ports on the

applicable port on the module and from the ends of the connectors.

The FE-100F3 uses Class 1 lasers. Do not use optical instruments to view the laser output. The use of optical

CAUTION

instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the network adapter.

Do not touch the ends of the ﬁber optic strands, and do not let the ends come in contact with dust, dirt, or other contaminants.

Contamination of the ends causes problems in data transmissions. If the ends become contaminated, blow the surfaces clean with a canned duster . A ﬁber port cleaning swab saturated with optical-grade isopropyl alcohol ma y also be used to clean the ﬁber optic ends.
