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.

1.3 OVERVIEW

The 6H122-16 (Figure 1-1) is a Fast Ethernet interface module for the Cabletron Systems 6C105 chassis. The module provides sixteen RJ45 switched ports for unshielded twisted pair (UTP) cabling connectivity.

The 6H122-16 is used to connect individual high-bandwidth user devices, such as workstations, and provide a central switching point for multiple 10/100 Mbps Fast Ethernet segments.

1.3.1 Connectivity

The 6H122-16 connects to Ethernet/Fast Ethernet networks or workstations through sixteen RJ45 ports on the front panel. These ports are IEEE 802.3u 100BASE-TX compliant, and use Category 5 unshielded twisted pair cables of lengths up to 100 meters with impedances between 85 and 111 ohms.

1.3.2 Management

Management of the 6H122-16 module and 6C105 chassis and any optional equipment is accomplished using Local Management tools or remote SNMP management stations. Local Management is accessible through the front panel RS232 COM port using a local VT100 terminal, or a remote VT100 terminal via a modem connection. Local Management is also accessible in-band via a Telnet connection. In-band remote management is possible through any SNMP compliant Network Management Software.

Chapter 1:

Introduction

1.3.3 Distributed Chassis Management

From a management perspective, the 6C105 SmartSwitch 6000 chassis can be viewed as a single entity with a single IP address. Its management functions are distributed to all modules. This means a single module in the chassis, such as the 6H122-16, can be used to manage the entire chassis, and any other attached module through Local Management, SNMP, or Telnet applications.

1.3.4 Switching Options

The 6H122-16 provides 802.1D switching, 802.1Q switching, or SecureFast Switching Virtual Network Services between all of the front panel interfaces.

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

1.3.5 Full Duplex Switched Ethernet

Ports 1 through 14 support Full Duplex Switched Ethernet (FDSE) operation if the port is operating in Standard Ethernet mode (10 Mbps). This provides up to 20 Mbps of bandwidth. Ports 15 and 16 also support Full Duplex operation in Fast Ethernet mode (100 Mbps). This provides up to 200 Mbps of bandwidth.

1.3.6 Remote Monitoring

The 6H122-16 supports all Ethernet Remote Monitoring (RMON) groups, which include Statistics, Alarms, Events and History. These four 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.

1-4 6H122-16 User’s Guide

Overview

1.3.7 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

1.3.8 Runtime IP Address Discovery

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

When the modules are connected to the network and powered up, Runtime IP Address Discovery (RAD) checks the modules for an IP address. If one has not yet been assigned (module and 6C105 chassis IP address set to 0.0.0.0), RAD checks to see if any of the module interfaces have a link. If so, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address from a RARP or BootP server on the network.

The RAD requests start out at an interval of one second. The interv al 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 RARP or BootP server, or an IP address is entered using Local Management.

6H122-16 User’s Guide 1-5

Chapter 1:

Introduction

1.3.9 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).

1.3.10 Auto-Negotiation

Twisted pair ports on the 6H122-16 module have the ability to 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, the 6H122-16 adjusts to 100 Mbps when the device on the other end of the connection can also adjust between 10 Mbps or 100 Mbps. If the device on the other end of the connection can only operate at 10 Mbps, then the 6H122-16 adjusts to 10 Mbps operation.

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 6H122-16 cannot auto-negotiate, the 6H122-16 interface operates according to the capabilities of the other device.

All ports support standard Ethernet, standard full duplex

NOTE

operation, and Fast Ethernet. Ports 1 through 14 do not support Fast Ethernet in full duplex operation. However, ports 15 and 16 do support full duplex Fast Ethernet.

1.3.11 Broadcast Suppression

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

Overview

1.3.12 Standards Compatibility

The 6H122-16 is fully compliant with the IEEE 802.3u standard. The 6H122-16 provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 6H122-16 supports 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.

1.3.13 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. Chapter 4 provides details about the 6H122-16 LANVIEW LEDs.

1.3.14 Year 2000 Compliant

The 6H122-16 module and 6C105 chassis have an internal clock that can maintain the time and date beyond the year 1999.

Ports 1 through 16 of the 6H122-16 are 10/100 ports with internal crossovers. The ports have RJ45 connectors for twisted pair connections. When connecting a workstation, use a straight-through cable. When connecting networking devices, such as another bridge, repeater, or router, use a crossover cable. To ensure proper operation, use Category 5 unshielded twisted pair (UTP) cabling that has an impedance between 85 and 111 ohms.

To connect a twisted pair segment to the 6H122-16, proceed as follows:

1. Ensure that the device connected to the other end of the segment is

powered ON.

2. Connect the twisted pair segment to the 6H122-16 by inserting the

RJ45 connector on the twisted pair segment into the desired RJ45 port (Ports 1 through 16) shown in Figure 3-2.
