FCC Notice — Class A Computing Device
iii
FCC Notice — Class A Computing Device
This equipment generates, uses, and may emit radio frequency energy. The equipment has been type
tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of FCC
rules, which are designed to provide reasonable protection against such radio frequency interference.
Operation of this equipment in a residential area may cause interference in which case the user at his
own expense will be required to take whatever measures may be required to correct the interference.
Any modifications to this device - unless expressly approved by the manufacturer - can void the user's
authority to operate this equipment under part 15 of the FCC rules.
Industry Canada Notice
This digital apparatus does not exceed the Class A limits for radio noise emissions from digital
apparatus set out in the Radio Interference Regulations of the Canadian Department of
Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables
aux appareils numériques de la class A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le ministère des Communications du Canada.
NOTICE: The Industry Canada label identifies certified equipment. This certification means that the
equipment meets telecommunications network protective, operational and safety requirements as
prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The
department does not guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the
facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. The customer should be aware that compliance with the above
conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be coordinated by a representative designated by the supplier.
Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give
the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power
utility, telephone lines and internal metallic water pipe system, if present, are connected together. This
precaution may be particularly important in rural areas. Caution: Users should not attempt to make
such connections themselves, but should contact the appropriate electric inspection authority, or
electrician, as appropriate.
NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal device provides an
indication of the maximum number of terminals allowed to be connected to a telephone interface. The
termination on an interface may consist of any combination of devices subject only to the requirement
that the sum of the ringer equivalence Numbers of all the devices does not exceed 5.

SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
The DGSRF-AA 100Base-FX Module, DGSRS-AA 1000Base-LX Module, and DGSRL-AA 1000Base-
LX Module use Class 1 Laser transceivers. Read the following safety information before installing
or operating these modules.
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 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 103W m2sr-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.
