Safety Information
CLASS 1 LASERTRANSCEIVERS
The 9H421-12, 9H429-12 and FE-100FX are Class 1 Laser Product
The 9H421-12, 9H429-12 and FE-100FX use a Class 1 Laser transceiver.
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 LASERTRANSCEIVERS
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 10
3
W m

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
The 9H421-12, 9H422-12 and the 9H429-12, shown in Figure 1-1, are Fast Ethernet
SmartSwitch
®
Modules for the SmartSwitch 9000.
The 9H422-12 is a twelve port switch module, with eleven 10BASE-T/100BASE-
TX ports and one FEPIM (Fast Ethernet Port Interface Module), on the front panel.
The FEPIM port accepts either the FE-100TX, for use with twisted pair copper, or
the FE-100FX, for use with mulitmode fiber optic cabling.
The 9H421-12 is a twelve port switch module, equipped with twelve 100BASE-FX
multimode fiber (MMF) ports.
The 9H429-12 is a twelve port switch module, equipped with twelve 100BASE-FX
single mode fiber (SMF) ports.
These modules connect to the SmartSwitch 9000 INB-2 backplane interface, and
employ the family of SmartSwitch ASICs, a high performance switch design, and
an Intel i960 microprocessor.
Features
Processor
The 9H421-12, 9H422-12, and the 9H429-12 are equipped with an advanced Intel
i960 microprocessor. This microprocessor provides a platform for all management
functions.
Packet Switch Engine
These modules incorporate the family of SmartSwitch ASICs, a collection of
custom ASICs designed specifically for high speed switching. The SmartSwitch
ASIC bus is 64 bits wide with a bandwidth of 845 Mbps. Since all frame
translation, address lookups, and forwarding decisions are performed in
hardware, these modules can obtain a throughput performance of greater than
990K pps.

Introduction
1-2
Management
The 9H421-12, 9H422-12 and the 9H429-12 modules support SNMP for local and
remote management. Local management is provided through the RS-232 Com
ports on the SmartSwitch 9000 Environmental Module using a standard VT-220
terminal or emulator. Remote management is possible through Cabletron’s
SPECTRUM or any SNMP compliant management tool as well as telneting to the
module. Management features include module configuration and statistics. All
Fast Ethernet interfaces provide frames filtered, frames forwarded, and all
Spanning Tree Protocol parameters. All modules support RMON (RFC-1757),
IETF MIB II (RFC-1213), IETF BRIDGE MIB (RFC-1493), and a host of Cabletron
enterprise MIBs. In addition, the front panel provides LEDs for link status per
port as well as transmit and receive activity.
Connectivity
The 9H421-12, 9H422-12 and the 9H429-12 modules have one interface to the INB-
2 and twelve front panel Fast Ethernet interfaces. The front panel connections for
the 9H422-12 are via eleven standard RJ45 connectors and one FEPIM.
Front panel connections for the 9H421-12 are via twelve standard multimode fiber
SC connectors, providing links up to 2000 meters in length, when operating in
half duplex (point to point) or full duplex. Distance of links on a shared LAN in
half duplex is 412 meters.
The 9H429-12 single mode SC connectors provide twelve Fast Ethernet 100BASE-
FX connections, with links up to 10000 to 15000 meters in length, when operating
in half duplex (point to point) or full duplex. Distance of links on a shared LAN in
half duplex is 412 meters.
Auto-negotiation
The auto-negotiation feature (available only with the 9H422-12 module) allows
the module to automatically use the fastest rate supported by the device at the
other end (either 10 Mbps or 100 Mbps at either half or full duplex). To negotiate
duplex, both the 9H422-12 and the attached device must be configured for auto-
negotiation. If only the 9H422-12 is configured for auto-negotiation, the module
will set the connection to half duplex at either the 10 Mbps or 100 Mbps rate. This
technology is similar to how modems negotiate transmission speed, finding the
highest transmission rate possible. Similarly, auto-negotiation determines the
highest common speed between two devices and communicates at that speed. If
no common speed is detected, the device will be partitioned.
All RJ45 connections are capable of auto-negotiation, and can operate at 10 Mbps
or 100 Mbps, full or half duplex. Fiber connections can only operate at the 100
Mbps rate, full or half duplex.
NOTE

Introduction
Management Information Base (MIB) Support
The 9H421-12, 9H422-12 and the 9H429-12 modules provide MIB support
including:
• Cabletron Fast Ethernet MIB
• IETF MIB II
• IETF Bridge MIB
• RMON
• a host of Cabletron Enterprise MIBs
LANVIEW LEDs
The 9H421-12, 9H422-12 and the 9H429-12 modules use LANVIEW – the
Cabletron Systems built-in visual diagnostic and status monitoring system. With
LANVIEW LEDs, you can quickly identify the device, port, and physical layer
status at a glance.
For a complete list of supported MIBs, refer to the release notes provided in the
9H421-12, 9H422-12 and the 9H429-12 module packages.

Installing the SmartSwitch 9000
Module
The 9H421-12, 9H422-12 and the 9H429-12 modules each occupy a single slot in
the SmartSwitch 9000 chassis.
Install any of these modules by following the steps starting below.
Unpacking the Module
1. Carefully remove the module from the shipping box. (Save the box and
packing materials in the event the module must be reshipped.)
2. Remove the module from the static bag. Observe all precautions to prevent
damage from Electrostatic Discharge (ESD).
3. Carefully examine the module, checking for damage. If any damage exists,
DO NOT install the module. Contact Cabletron Systems Technical Support
immediately.
Installing an FEPIM
The 9H422-12 provides a slot for a Cabletron FEPIM (Fast Ethernet Port Interface
Module). The 9H422-12 SmartSwitch module is shipped without an FEPIM. To
install an FEPIM, follow the procedure below:
1. Remove the module if it is installed in the SmartSwitch 9000 chassis.
2. Remove the two screws securing the plate on the side of the FEPIM slot.
3. Install the FEPIM as shown in Figure 2-1. Ensure that the rear connector is
seated firmly before tightening the three mounting screws.
4. Replace the plate and two screws on the side of the FEPIM slot.
