Safety Information

CLASS 1 LASER TRANSCEIVERS

The 9G429-02 is a Class 1 Laser Product

The 9G429-02 uses a Class 1 Laser transceiver . Read the f ollowing saf ety

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.

Laser Radiation and Connectors

When the connector is in place, all laser radiation remains within the Þber. The maximum amount of
radiant power exiting the Þber (under normal conditions) is -12.6 dBm or 55 x 10

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
or 8 x 10

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.

panel gigabit Þber optic ports provide connectivity through SC connectors.

As shown in Figure 3-1, Gigabit Network Interface Blocks (GNIBs) convert data
packets received from the gigabit optics port into a canonical frame format before
forwarding to the SmartSwitch ASIC. The Internal Network Bus Network
Interface Block (INB NIB) converts data packets received from the INB into a
canonical format before forwarding to the SmartSwitch ASIC.

Operation

System Management Buses

There are two management channels within the SmartSwitch 9000 system: the
SMB-1 and the SMB-10. These buses provide side-band management and inter­module management communication.

SMB-1 Bus

The SMB-1 is a 1 Mbps management bus located within the SmartSwitch 9000.
This bus is utilized by all diagnostic controllers in the system, including
connectivity modules, power supply modules and the environmental module.
The SMB-1 transports inter-chassis information between system components,
such as power and environmental information, as well as diagnostic messages.
Periodic loop-back tests are performed by all modules that share this bus to
ensure the validity of SMB-1. In the event a failure is detected on SMB-1, the
SMB-10 may be used as an alternate communication channel.

SMB-10 Bus

The SMB-10 is a 10 Mbps management bus located within the SmartSwitch 9000.
This bus is used for inter-chassis communication of modules as well as serving as
a side-band management channel into the SmartSwitch 9000. The SMB-10 is
externalized from the chassis via an optional Ethernet Port Interface Module
(EPIM) located on the front of the Environmental Module. Through an EPIM
connection, full-SNMP management of the SmartSwitch 9000 is available out-of­band from user data. Modules that share the SMB-10 bus periodically send out
loop-back packets to ensure the validity of SMB-10. If a fault is detected on the
SMB-10, the SMB-1 can be used as an alternate communication channel by the
modules.

System Diagnostic Controller

This diagnostic controller is composed of a Z-80 microprocessor and its
supporting logic. The diagnostic controller is designed to control the power-up
sequencing of modules, monitor the 9G421-02/9G429-02 input and output power
parameters, keep watch over the main host processor, monitor the temperature,
and control the SMB LANVIEW diagnostic LEDs. Although the system diagnostic
controller and the main host processor can operate independently of each other if
needed, they exchange status information and overall module condition. The
information gathered by the diagnostic controller is available to the network
manager via local/remote management and the LCD located on the environment
module. The 9G421-02/9G429-02 is designed to continue functioning in the event
of a diagnostic controller fault.

3-2

DC/DC Converter

The DC/DC converter converts the 48 VDC on the system power bus to the
necessary operating voltages for its host network services module. The diagnostic
controller monitors and controls the operation of the DC/DC converter.

INB Interface

Each module attaches to both INB A and INB B and has two INB Network
Interface BlockÕs (NIB). The INB NIBs convert canonical frames to Þxed length
data blocks for transmission onto the INBs. For data blocks received from either
INB, the INB NIB reassembles the data blocks received from the INB back into
canonical frames for transmission back through the switching fabric to the front
panel ports.

SecureFast SmartSwitch Architecture

Operation

The SecureFast SmartSwitch Architecture of the 9G421-02/9G429-02 module is
conÞgurable for one of two modes of operation: traditional switching (bridging),
or SecureFast switching. The module supports only one of these modes of
operation at any one time.

When operating in traditional switch mode, the 9G421-02/9G429-02 makes
Þltering/forwarding decisions based on Destination Address (DA), with standard
IEEE 802.1D learning. Spanning tree operation for the 9G421-02/9G429-02 is
conÞgurable to adhere to IEEE 802.1D, DEC, or none. The default Spanning Tree
Algorithm is 802.1D.

When operating in SecureFast switching mode, all Þltering/forwarding decisions
are made on a DA-SA pair and its receive port. SecureFast switching mode
provides value-added network services including Topology, Connectivity, IP
Multicast, Control, Security, Application, Address Management, Dynamic
Mapping, and Directory services. For example, Topology Services included
conÞgurable options ranging from simple spanning tree implementations to
fully-meshed active topologies. Other services and features supported in
SecureFast switching mode are described in detail in the Cabletron White Paper,
IP Host Communication in Bridged, Routed and SecureFast Networks.

3-3

Operation

i960 Core

The i960 core supports a high-speed, software-based look-up function involved in
performing Þltering/forwarding decisions on incoming data frames. In addition,
the i960 core provides the SNMP protocol stacks, to support industry standard
MIBs, as well as Cabletron enterprise extension MIBs for each media type.
Management services, such as telnet and network address to MAC address
mapping, are also provided by the i960 core.
