Safety Information
CLASS 1 LASERTRANSCEIVERS
The 9G429-02 is a Class 1 Laser Product
The 9G429-02 uses 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.
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
-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
2
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 9G421-02/9G429-02 (Figure 1-1) is a Gigabit Ethernet interface module,
occupying a single slot in the SmartSwitch 9000 chassis. Gigabit Ethernet
networks are connected to the 9G421-02/9G429-02 through front panel ports.
These ports interface with the switch through Gigabit Network Interface Blocks
(GNIB) and are based upon an ASIC architecture.
The module connects to the Internal Network Bus (INB) B, providing a high
speed backplane for communication among other modules in the SmartSwitch
9000 chassis. The 9G421-02/9G429-02 uses a SmartSwitch ASIC design and an
advanced Intel i960
¨
microprocessor providing a platform for all management
functions within a scalable RISC-Based Architecture.
