READ THE FOLLOWING SAFETY INFORMATION BEFORE

INSTALLING OR OPERATING THESE ADAPTERS.

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.

Introduction

1.4 OVERVIEW

The HSIM-F6 extends the functionality of certain Cabletron Systems interface modules or standalone hubs to include high-speed uplink capability. The HSIM-F6 allows remote connectivity using FDDI technology.

1.4.1 Features

Connectivity

The HSIM-F6 is equipped with slots for FDDI A and B ports. These two ports allow connection to the ring as a Dual Attached Station (D AS) using two FPIMs or as a Single Attached Station (SAS) using one FPIM.

As a DAS, the module or standalone hub that houses the HSIM-F6 connects directly to the FDDI primary ring. This provides the reliability of an FDDI dual, counter-rotating ring topology. If one segment of the FDDI ring becomes disabled, this dual ring conﬁguration provides redundancy and restores ring continuity.

As a SAS, the HSIM-F6 connects to the primary ring only by using a single FPIM on the HSIM-F6 to attach to the M port of an FDDI concentrator.

The HSIM-F6 also supports dual homing. A dual homing conﬁguration provides additional redundancy for the module or hub containing the HSIM-F6. Dual homing is a way of connecting to an FDDI ring through the Master (M type) ports of two separate dual attached concentrators. If one M type port or one segment fails, the redundant port or segment activates automatically to retain connection to the ring.

The HSIM-F6 is also capable of operating in full duplex mode, which creates a point-to-point link between two FDDI devices. This allows for a data rate of 200 Mbps, with each device transmitting and receiving at 100 Mbps simultaneously. Chapter 3,

Local Management

, provides

instructions on conﬁguring the HSIM-F6 to operate in full duplex mode.

Bridging

The HSIM-F6 provides translational bridging between any channels or ports in its host module or hub and the FDDI ring.

The HSIM-F6 FDDI Ring Statistics screen allows the user to monitor the current HSIM-F6 operational status.

The following list describes the Ring Statistics screen ﬁelds:

RING STATE

Displays the current ring state. The possible ring states are as follows:

• Ring-Op - The ring is functioning correctly.

• Isolated - The HSIM-F6 is not attached to the ring.

• Non-Op - The HSIM-F6 is attempting to enter the ring.

• Detect - The claim (beacon) process of the FDDI ring

protocol has exceeded one second. There may be a problem.

• Non-Op-Dup - The ring failed to complete the claim (beacon)

process. This usually indicates a duplicate FDDI address.

• Ring-Op-Dup - The ring is operational, but a duplicate FDDI

address may be present somewhere on the network.

• Directed - The claim (beacon) process did not complete

within ten seconds. The HSIM-F6 is sending directed beacons to indicate a problem.

• Trace - A problem has been detected with the HSIM-F6 or

the nearest active upstream neighbor (NAUN). A trace is being sent to notify the nearest active upstream neighbor of the problem.

RING-OP COUNT

The Ring-Op Count keeps track of the number of times the FDDI ring has initialized since the last time the HSIM-F6 (or host device in which it resides) was reset. If this number grows steadily over a brief period of time, it signiﬁes the ring is unstable.

MAC CONFIGURATION

The MAC Conﬁguration ﬁeld describes the current conﬁguration of the Media Access Control (MAC) and physical layers of the A and B ports. The possible port conﬁgurations are as follows:

• Through-A - The ﬂow of the primary ring is entering the MAC from

port A (primary ring in) and e xiting through port B (primary ring out). The secondary ring is isolated from the MAC with the ﬂow entering from port B (secondary ring in) and exiting through port A (secondary ring out). In a normal ring state the HSIM-F6 MAC Conﬁguration should read “Through-A”.

• Wrap-A - The ﬂow of the primary ring is entering through port A

(primary in) and is wrapped by the MAC, causing the ring to exit through port A (secondary out). Port B is disconnected from the ring. If the HSIM-F6 MAC Conﬁguration reads “Wrap-A” the ring has lost the redundancy of the secondary ring due to the wrapped condition. This conﬁguration should be repaired, as additional problems could isolate stations from the FDDI ring.

The Ring Map Conﬁguration screen displays node class, node address, and twisted and/or wrapped conditions (T for twisted and/or W for wrapped) in parentheses. The following list provides the node class possibilities:

NAS - (Null Attached Station) Isolated station; station not connected to

an FDDI Ring.

DAS - (Dual Attached Station) Station does not support M (Master)

ports, but does connect directly to an FDDI primary and secondary ring using A and B ports.

DAC - (Dual Attached Concentrator) Station that supports M (Master)

ports and provides access for multiple stations. A DAC connects directly to an FDDI ring using A and B ports.

SAS - (Single Attached Station) Station that accesses the primary ring

only, via a concentrator.

SAC - (Single Attached Concentrator) Station that accesses the primary

ring only and provides access for multiple Single Attached Stations (SAS). Single Attached Concentrators provide the same services as DACs, but without the redundancy of the dual ring topology.

Chapter 3: Local Management

3.9.1 Full Duplex FDDI

Full duplex FDDI is the creation of a 200 Mbps point-to-point link between two FDDI devices that support full duplex FDDI operation. Full duplex FDDI is a technology where the end devices simultaneously transmit and receive data at 100 Mbps. For the HSIM-F6 to operate in full duplex mode, speciﬁc criteria must be met. Before conﬁguring the HSIM-F6 to operate in full duplex mode, ensure that the network conﬁguration meets the following requirements.

• The FDDI device that connects to the HSIM-F6 must be a Cabletron

Systems product that supports full duplex FDDI (e.g., 9F426-02 MMAC-Plus SmartSwitch module, or another HSIM-F6).

• Full duplex FDDI is a point-to-point link between two devices that

support full duplex operation. No other stations may be present on the ring. If a third station is added, the HSIM-F6 automatically returns to standard FDDI operation.

• There must be two FPIMs installed in the HSIM-F6 to connect to the

other full duplex FDDI device. To operate in full duplex mode, one port transmits data while the other receives data simultaneously. Cabletron Systems recommends that the connection between the two devices be made from the A port of one device, to the B port of the other.

NOTE

3-24 HSIM-F6 User’s Guide

Making a connection between the A ports of both devices to the B ports of both devices (as is done with a DAS in normal FDDI operation) DOES NOT create a redundant path when using full duplex FDDI.

The Interpret 802.3 Length for Frames > 64 Bytes

This ﬁeld allows the user to enable the HSIM-F6 to examine the length ﬁeld of an 802.3 Ethernet frame to determine if the sending device has added padding to a frame that contains more than the Ethernet minimum of 64 bytes. If padding has been added, the HSIM-F6 removes any padding before sending the frame onto the FDDI ring.

NOTE

HSIM-F6 User’s Guide 3-29

The HSIM-F6 automatically checks for padding all Ethernet frames that are the minimum 64 bytes in length.

Chapter 3: Local Management

The Interpret 802.3 length for frames > 64 bytes ﬁeld toggles between the following options:

• [DISABLED] (default setting)

• [ENABLED]

If you retain the default setting of [DISABLED], the HSIM-F6 only examines 802.3 frames that are the Ethernet minimum 64 bytes in length. This allows for optimal switching performance, as the HSIM-F6 assumes all frames over 64 bytes in length contain no padding.

If this ﬁeld is set to [ENABLED] the HSIM-F6 examines ALL 802.3 frame length ﬁelds to determine whether any of the frames contain padding. In this setting, the HSIM-F6 removes unnecessary padding from any 802.3 frame, regardless of the size. Refer to Section 3.10.4 for information on when to set this ﬁeld to [ENABLED]. Section 3.10.5 describes how to perform this task.

> 64 Bytes Field to [ENABLED]

In most network conﬁgurations, the default setting of [DISABLED] is appropriate. Some Ethernet devices, however, add padding to frames that are larger than the Ethernet minimum of 64 bytes. If network problems arise with the HSIM-F6 switching frames that contain padding, this ﬁeld may need to be set to [ENABLED]. If you are not sure what is causing the problem, contact Cabletron Systems Global Call Center. Refer to

Section 1.3, Getting Help.

4.1 HSIM-F6 LED STATE DEFINITIONS

• Through-A - The ﬂow of the primary ring is entering the MAC from

• Through-B - The ﬂow of the primary ring is entering the MAC from

port B (primary ring in) and exiting through port A (primary ring out). The secondary ring is isolated from the MAC with the ﬂow entering from port A (secondary ring in) and e xiting through port B (secondary ring out).

HSIM-F6 User’s Guide 4-3

Chapter 4: LANVIEW LEDs

• Wrap-A - The ﬂow of the primary ring is entering through port A

(primary in) and is wrapped by the HSIM-F6, causing the ring to exit through port A (secondary out). Port B is disconnected from the ring. If the HSIM-F6 LED state indicates “Wrap-A” the ring has lost the redundancy of the secondary ring due to the wrapped condition. This conﬁguration should be repaired, as additional problems could isolate stations from the FDDI ring.

• Wrap-B - The ﬂow of the primary ring is entering through port B

(secondary in) and is wrapped by the HSIM-F6, causing the ring to exit through port B (primary out). Port A is disconnected from the ring. If the HSIM-F6 LED state indicates “Wrap-B” the ring has lost the redundancy of the secondary ring due to the wrapped condition. This conﬁguration should be repaired, as additional problems could isolate stations from the FDDI ring.

• Isolated - Both port A and port B are isolated from the ring.

• Dual Homed (Default) - The ﬂow of the primary ring is entering

through port B (primary in) and is wrapped by the HSIM-F6, causing the ring to exit through port B (secondary out). Port A is in standby mode, and will take over the functions of port B if port B leaves the ring. This LED sequence is the default setting if the HSIM-F6 is conﬁgured to be a dual homed device.

• Dual Homed (Modiﬁed) - The ﬂow of the primary ring is entering

through port B (primary in) and is wrapped by the HSIM-F6, causing the ring to exit through port B (secondary out). Port A is in standby mode, and will take over the functions of port B if port B leaves the ring. This dual homed LED sequence is set by setting the OID ctsmtmibDualHomeWrpLEDStatus to off.

• Twisted Ring (A-A, B-B) - This condition indicates that the A port

of the HSIM-F6 is connected to the A port of another device, and the B port of the HSIM-F6 is connected to the B port of the other device. This is an undesirable ring condition and should be repaired as some stations could be isolated from the primary ring.

4-4 HSIM-F6 User’s Guide

HSIM-F6 LED State Deﬁnitions

• Twisted Ring (A-A)/Wrap-A - This condition indicates that the A

port of the HSIM-F6 is connected to the A port of another device. It also indicates that the A port has wrapped, combining the primary and secondary rings into a single ring. This is an undesirable ring condition and should be repaired as some stations could be isolated from the primary ring.

• Twisted Ring (B-B)/Wrap-B - This condition indicates that the B

port of the HSIM-F6 is connected to the B port of another device. It also indicates that the B port has wrapped, combining the primary and secondary rings into a single ring. This is an undesirable ring condition and should be repaired as some stations could be isolated from the primary ring.

• Full Duplex - The HSIM-F6 has been conﬁgured to operate in full

duplex mode. For more information on full duplex mode for the HSIM-F6 refer to Chapter 3, Local Management.

• Wrap S (Port A) - The HSIM-F6 has only one FPIM installed. The

FPIM is installed in port A.

• Wrap S (Port B) - The HSIM-F6 has only one FPIM installed. The

FPIM is installed in port B.
