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 2H28-08R also has two slots (7 and 8) for optional Fast Ethernet Interface Modules.

The device bridges each Ethernet segment to the other switch ports, and to the optional interface modules in port slots 7 and 8. The optional Fast Ethernet Interface Modules provide uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet networks, and connectivity to 10BASE-T.

1-2 2H28-08R SmartSwitch 2208 User’s Guide

2H28-08R Overview

The 2H28-08R may be used as a tabletop unit or can be installed in a standard 19-inch rack using the supplied rack mounting hardware.

The 2H28-08R has two power supplies. Both are universal ac power supplies with automatic voltage sensing that allows operation using 100–125 or 200–240 Vac, 50/60 Hz. The power supplies load share 50% (+/-5%) of the power required by the device. If one po wer 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.

1.3.1 Connectivity

The six ﬁxed ports on the 2H28-08R connect to Ethernet networks or workstations using SC ﬁber optic connectors.

The 2H28-08R has two front panel slots (ports 7 and 8) for optional Fast Ethernet Interface Modules to support an uplink to 100 Mbps Fast Ethernet backbones, a high speed connection to a local server, or a connection to 10BASE-T.

1.3.2 Switching Options

The 2H28-08R provides traditional switching (IEEE 802.1D bridging), IEEE 802.1Q, or SecureFast Switching V irtual Network Services between all of the front panel interfaces including the optional Fast Ethernet Interface Modules. SecureFast Switching and IEEE 802.1Q allow for migration to Virtual Network technologies without requiring the replacement of existing equipment.

1.3.3 Full Duplex Switched Ethernet

All the ports for the 2H28-08R, including the optional modules, can be conﬁgured to operate in Full Duplex Switched Ethernet mode, which provides 200 Mbps of throughput.

Chapter 1:

Introduction

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 2H28-08R to automatically accept an IP address from a Bootstrap Protocol (BootP) server on the network into NVRAM without requiring a user to enter an IP address through Local Management.

When the 2H28-08R is connected to the network and powered up, Runtime IP Address Discovery (RAD) checks the 2H28-08R for an IP address. If one has not been assigned (2H28-08R default IP address set to

0.0.0.0), RAD checks to see if any of the 2H28-08R 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 2H28-08R SmartSwitch 2208 User’s Guide

2H28-08R Overview

1.3.6 Management

Management of the 2H28-08R 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 2H28-08R and any of the optional Fast Ethernet Interface Modules installed in ports 7 and 8.

1.3.7 Remote Monitoring (RMON)

The 2H28-08R supports all Ethernet RMON groups, which include Statistics, Alarms, Events and History. These groups are enabled on all ports by default.

Cabletron Systems RMON Actions is a vendor speciﬁc extension of RMON and provides the ability to set an “Action” on any SNMP MIB variable. The Action can be triggered by any RMON Event and/or Alarm. An example of an Action would be to turn off a MIB-2 interface if a broadcast threshold is crossed.

1.3.8 LANVIEW Diagnostic LEDs

LANVIEW diagnostic LEDs serve as an important troubleshooting aid by providing an easy way to observe the status of indi vidual ports and overall network operations.

1.3.9 Broadcast Suppression

Broadcast Suppression allows a user to set a desired limit of receive broadcast frames per port/per second to be forwarded out the other ports on the module up to the set limit. Any broadcast frames above this speciﬁed limit are dropped. In the event that broadcast frames are being suppressed, multicast and unicast frames continue to be switched.

2H28-08R SmartSwitch 2208 User’s Guide 1-5

Chapter 1:

Introduction

1.3.10 Port Redirect Function

The port redirect function, also referred to as “Port Mirroring,” is a troubleshooting tool used to map trafﬁc from a single source port or multiple source ports to a destination port(s) within the chassis. This feature functions at the bit level, which allo ws all packets, including those with errors, to be copied and sent to an analyzer or RMON probe. The analyzer or RMON probe will see the data as if it is directly connected to the LAN segment of the source port(s).

1.3.11 Year 2000 Compliance

The 2H28-08R has an internal clock that can maintain the time and date beyond the year 1999.

1.3.12 Standards Compatibility

The 2H28-08R is fully compliant with the IEEE 802.3 standard. The optional Fast Ethernet Interface Modules are fully compliant with the IEEE 802.3u standard.The 2H28-08R provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 2H28-08R supports a wide variety of industry standard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1493 (Bridge MIB), RFC 1354 (FIB MIB), RFC 1191 (Path MTU Discovery), and RFC 1317 (RS232 MIB). A full suite of Cabletron Systems Enterprise MIBs provide a wide array of statistical information to enhance troubleshooting.
