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.

2H22-08R Overview

1.3 2H22-08R OVERVIEW

The 2H22-08R is a Fast Ethernet standalone device that has six RJ45 switched ports and two optional Fast Ethernet Interface Module ports (100BASE-TX, 100BASE-FX, and 100BASE-F3) that provide twisted pair, multimode, and single mode ﬁber optic cabling connectivity.

RESET

2H22-08R

COM

The 2H22-08R supports traditional IEEE 802.1d switching (bridging), IEEE 802.Q switching, and Cabletron Systems S Virtual Netw ork technology. The 2H22-08R 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 Auto-Negotiation

Twisted Pair ports on the 2H22-08R can auto-negotiate the type of connection required to provide a link to another device. During Auto-Negotiation, two devices automatically exchange information concerning their operating capabilities. The Auto-Negotiation feature targets the maximum capabilities between the two devices. For example, the 2H22-08R adjusts to 100 Mbps when the device on the other end of the connection can 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 2H22-08R 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 2H22-08R cannot auto-negotiate, the 2H22-08R interface operates according to the capabilities of the other device.

2H22-08R SmartSwitch 2208 User’s Guide Page 1-3

Chapter 1:

Introduction

1.3.2 Connectivity

The 2H22-08R connects to Ethernet networks or workstations through six RJ45 ports on the front panel. These ports support Category 5 unshielded and shielded twisted pair cables of lengths up to 100 meters. These ports are IEEE 802.3u 100BASE-TX compliant.

The 2H22-08R has two front panel slots (ports 7 and 8) for optional Fast Ethernet Interface Modules (FE-100TX, FE-100FX, and FE-100F3) to support an uplink to 100 Mbps Fast Ethernet backbones or a high speed connection to a local server using twisted pair, multimode or single mode ﬁber optic cabling.

1.3.3 Runtime IP Address Discovery

This feature enables the 2H22-08R 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 2H22-08R is connected to the network and powered up, Runtime IP Address Discovery (RAD) checks the 2H22-08R for an IP address. If one has not yet been assigned (2H22-08R IP address set to

0.0.0.0), RAD checks to see if any of the 2H22-08R 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.

2H22-08R Overview

1.3.4 Remote Monitoring (RMON)

The 2H22-08R supports all Ethernet RMON groups, which include Statistics, Alarms, Ev ents and History as the default groups enabled on all ports, and Capture, Filter, and Host as the groups that are off 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. The Action can be, for example, to turn a MIB-2 interface off if a broadcast threshold is crossed.

1.3.5 Switching Options

The 2H22-08R provides traditional Switching (802.1D), IEEE 802.1Q, or S

ECUREFAST

panel interfaces including Fast Ethernet Interface Modules. S

Switching Virtual Network Services between all of the front

ECUREFAST

Switching and IEEE 802.1Q allows for migration to Virtual Network technologies without requiring the replacement of existing equipment.

1.3.6 Standards Compatibility

The 2H22-08R provides IEEE 802.1, 802.1u, 802.1D and DEC Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 2H22-08R 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 provides a wide array of statistical information to enhance troubleshooting.

1.3.7 Year 2000 Compliant

The 2H22-08R has an internal clock that can maintain the current time and date beyond the year 1999.

1.3.8 LANVIEW Diagnostic LEDs

The various conditions of the LANVIEW diagnostic LEDs serve as important troubleshooting aids. They provide an easy way to observe the transmit and receive status of individual ports and overall network operations such as system status, switching conﬁguration, and Fast Ethernet channel usage. LANVIEW LEDs.

Chapter 1:

Introduction

1.4 LOCAL MANAGEMENT

Management of the 2H22-08R is accomplished using Local Management tools or remote Simple Network Management Protocol (SNMP) management stations. Out-of-band Local Management is accessible through the RS232 COM port on the front panel using a VT100 terminal, or a remote VT100 terminal emulator 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 tools to manage the 2H22-08R, and its two Fast Ethernet Interface Modules. It also allows the following tasks to be performed:

•

Assign an IP address and subnet mask to the 2H22-08R.

•

Select a default gateway and default interface.

•

Control local and remote access.

•

Designate workstations to receive SNMP traps from the 2H22-08R.

Chapter 5

provides detailed information about Local Management of the 2H22-08R, and its two optional Fast Ethernet Interface Modules. Local Management also provides the features detailed in Section 1.4.1 through

Section 1.4.4.

1.4.1 Broadcast Suppression

Broadcast Suppression allows a user to set a desired limit of receive broadcast frames per port/per second to be forwarded out of 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 without suppression.

Local Management

1.4.2 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 Destination ports(s) within the chassis. This feature functions at the bit level, which allows all packets, including, if desired, those with errors, to be copied and sent to an analyzer or RMON probe that appears as if it is directly connected to the LAN segment of the source port(s).

1.4.3 Full Duplex Switched Ethernet (FDSE)

Each switched Fast Ethernet port on the 2H22-08R supports 10/100 Mbps operation and can be conﬁgured to operate in Full Duplex Switched Ethernet (FDSE) mode. FDSE allows each Fast Ethernet port to provide up to 200 Mbps of aggregate throughput bandwidth.

1.4.4 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.

SmartTrunking on the 2H22-08R is available to group the optional Fast Ethernet Interface Module ports 7 and 8.

For more information about SmartTrunk, refer to the Cabletron Systems SmartTrunk User’s Guide.

LOCAL MANAGEMENT

This chapter explains how to set up a management terminal to the 2H22-08R, and access the 2H22-08R using its Local Management screens and commands.

5.1 OVERVIEW

Local Management is a series of management screens that allows you to conﬁgure the 2H22-08R. The management screens allow you to do the following tasks:

• Assign IP addresses and subnet masks to the 2H22-08R

• Assign a default gateway

• Control access to the 2H22-08R by establishing Community Names

• Download a new image of operating software

• Designate which Network Management Workstations receive SNMP

traps from the 2H22-08R

• View switch, interface, and RMON statistics

• Assign ports to operate in Auto-Negotiate, standard or full duplex

mode

• Perform load sharing by SmartTrunking ports

• Conﬁgure optional Fast Ethernet Interface Modules of the 2H22-08R

• Clear NVRAM, allows user-entered parameters such as an IP address

or Community Names to be deleted.

There are three ways to access Local Management:

• Locally using a VT type terminal connected to the COM port of the

2H22-08R

• Remotely using a VT type terminal connected through a modem

• In-band through a Telnet connection

In normal operation, the installed FE-100TX port automatically establishes a link with the device at the other end of the segment without requiring user setup. However, Local Management allows you to optionally conﬁgure that port.

Chapter 5: Local Management

Advertised Ability (Selectable)

During auto-negotiation, the FE-100TX sends information about its capability to the device at the other end of the segment. The capabilities of a port with an FE-100TX installed are 10BASE-T, 10BASE-TFD (full duplex mode), 100BASE-TX and 100BASE-TXFD (full duplex mode). In normal operation, with all capabilities enabled, the FE-100TX “advertises” that it has the ability to operate in any mode. The Network Manager may choose to set up the port so that only a portion of the available capabilities are advertised and the others are disabled. For example, only 100BASE-TX and 100BASE-TXFD might be enabled so that only devices that operate at 100 Mbps can communicate with that port. Section 5.11.3 describes how to enable or disable advertised modes.

Flow Control Admin Status (Selectable)

This setting controls whether or not the switch will send a jam out all ports when there is too much trafﬁc for the switch to process. The jam will clear the ports and enable the switch to process the current frame information. It will enable the optional ports, 7 and 8, to continue to pass trafﬁc, giving those two ports priority. Section 5.11.3 describes the how to enable or disable advertised modes.

5.11.1 Conﬁguring an FE-100TX Interface

In normal operation, a port with an FE-100TX interface automatically establishes a link with the device at the other end of the segment and no user setup is required. Section 5.11.2 and Section 5.11.3 provide instructions for manually conﬁguring the port with an FE-100TX installed.
