Safety Information
CLASS 1 LASERTRANSCEIVERS
The GPIM-F01 is a Class 1 Laser Product
The GPIM-F01 uses Class 1 Laser transceivers.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

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 9G426-02 (Figure 1-1) is a two front panel port switching module, occupying
a single slot in the MMAC chassis. The module connects to the Internal Network
Bus B, providing a high speed backplane for communication among other
modules in the MMAC-Plus chassis. This module uses a SmartSwitch ASIC
design and an advanced Intel i960
®
microprocessor. This microprocessor provides
a platform for all management functions within a scalable RISC-Based
Architecture.
Network management information is available through a variety of methods. All
information based on Simple Network Management Protocol (SNMP) is
accessible either via an in-band (Front Panel port), Side Band (SMB-10), or via the
Environmental Module’s COM ports. Serial Line Internet Protocol (SLIP) or
Point-to-Point Protocol (PPP) are supported by the Environmental Module’s
COM ports. For more information on the SMB-10, SLIP or PPP refer to the
MMAC-Plus Local Management User’s Guide.
The 9G426-02 also features front panel LANVIEW™ Diagnostic LED’s to offer at-
a-glance status information about each front panel port as well as the operation of
the overall module.
Ethernet networks are connected to the 9G426-02 module through GPIMs built
into the front of the module. These ports interface with the FPS switch through
GIGA-BIT Network Interface Blocks (GNIB) and are based upon an ASIC
architecture. The GPIMs are Fiber Channel and are MMF with SC connectors.
The 9G426-02 Module uses GPIMs which utilize a 850 nanometer laser. Follow
applicable safety precautions when using this module to prevent injury.

Features
Processor
The 9G426-02 is equipped with an advanced Intel i960 microprocessor. This
microprocessor provides a platform for all management functions such as
Spanning Tree, RMON, and MIB support within a scalable RISC-Based
architecture.
Fast Packet Switching
The 9G426-02 incorporates a hardware based switch design referred to as the
SmartSwitch ASIC, a collection of custom ASICs designed specifically for high
speed switching. Because all frame translation, address lookups, and forwarding
decisions are performed in hardware, the 9G426-02 can obtain a throughput
performance of greater than 750K pps.
Management
The 9G426-02 features SNMP for local and remote management. Local
management is provided through the RS-232 Com ports on the MMAC-Plus
Environmental Module using a standard VT-220 terminal or emulator. Remote
management is possible through Cabletron’s SPECTRUM or any SNMP
compliant management tool. Included as management features are the IETF
Standard Management Information Base (MIBs) RMON (RFC1271), IETF MIB II
(RFC-1213), IETF Bridge MIB (RFC-1493), and a host of other Cabletron enterprise
MIBs. The 9G426-02 also offers the user a wide variety of statistical network
management information to enhance network planning and troubleshooting. This
module provides information for each front panel Ethernet Gigabit port,
including packet counts along with errored frame information such as collisions,
CRCs, and Giants, via a variety of industry standard and private MIBS. Industry
standard IEEE 802.1d bridging, including Spanning Tree Algorithm, is supported.
Connectivity
The 9G426-02 module has one interface to the INB and two front panel MMF SC
connectors. The INB interface is a fixed connection to INB-2 which allows the
9G426-02 to communicate with other MMAC-Plus modules supporting various
LAN technologies including: Token Ring, FDDI, Ethernet, WAN and ATM. Each
front panel MMF SC connector provides 1 Ethernet Gigabit connection for MMF
links up to 100 meters in length.
Standard Ethernet/Full Duplex Operation
The 9G426-02 Module supports MMF. The use of MMF allows each port on the
9G426-02 Module to operate in full duplex mode.

Introduction
Management Information Base (MIB) Support
The 9G426-02 provides MIB support including:
• RMON (RFC-1271)
• IETF MIB II (RFC-1213)
• IETF Bridge MIB (RFC-1493)
and a host of other Cabletron Enterprise MIBs.
LANVIEW LEDs
The 9G426-02 uses LANVIEW – the Cabletron Systems built-in visual diagnostic
and status monitoring system. With LANVIEW LEDs you can quickly identify, at-
a-glance, system status as well as the device, port, and physical layer status. Two
LEDs indicate the transmission and reception of data from the INB MMAC-Plus
backplane connection. Each of the 2 Ethernet front panel ports features two LEDs
per port to indicate the port’s Administrative status (enabled/disabled), LINK
status (Link/Nolink), and Data Activity (receiving and transmitting data).
For a complete list of supported MIBs, refer to the release notes provided in
the 9G426-02 package.

Installing the 9G426-02 Module
This chapter describes the physical layout of the 9G426-02 Module and explains
how to prepare and install the module in an MMAC-Plus chassis.
The 9G426-02 module occupies a single slot in the MMAC-Plus chassis. Install the
9G426-02 module 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 plastic 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.
Never expose the module’s components to Electrostatic Discharge. Make sure you have
attached the module’s disposable grounding strap to your wrist and always place the
module on a non-conductive surface.
!
CAUTION
The INB Terminator Modules must be installed on the rear of the chassis before powering
up this module. Refer to the INB Terminator Modules Installation Guide for
information and installation procedure.

The Module’s Physical Layout
The 9G426-02 Module has two major circuit boards on which components are
attached (see Figure 2-1). The module’s base-level circuit board is known as the
motherboard. The module’s second-level circuit board is known as the
daughterboard. The removable daughterboard attaches to the motherboard’s
connectors and standoffs. Both the motherboard and the daughterboard contain
components that are accessible to the user.

User Accessible Components on the Module’s
Daughterboard
The user accessible components on the module’s daughterboard are located on
the underside of the daughterboard. These components include an eight position
DIP switch, a replaceable SMB-1 PROM, a replaceable BOOT PROM, and sockets
for DRAM and FLASH memory. You can access the DIP switch without
removing the daughterboard. However, to access the other user-accessible
components on the daughterboard, you must remove the daughterboard from the
motherboard.
DIP Switch
An eight position DIP switch is located on the module’s daughterboard as shown
in Figure 2-2. The functions of the switches are listed in Table 2-1.
