Connections

Fiber Optic ports - Optical Safety. To protect your eyes, never look at the transmit LED/laser through a
magnifying device while it is powered on. Never look directly at a fiber port on the switch or at the
ends of fiber cable when they are powered on.
This is a Class 1 laser device.
WARNING!
Use fiber optic ports only for data communications applications that require optical fiber. Use only with
the appropriate connector. When not in use, replace dust cover. Using this module in ways other than
those described in this manual can result in intense heat that can cause fire, property damage, or
personal injury.

Lithium Battery

The battery in the bq4830/DS1644 device is encapsulated and not user-replaceable. The battery is
located on the MSM motherboard for the BlackDiamond switch.
If service personnel disregard the instructions and attempt to replace the bq4830/DS1644, replace the
lithium battery with the same or equivalent type, as recommended by the manufacturer.
WARNING!
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type
recommended by the manufacturer. Dispose of used batteries according to the manufacturer's
instructions.
• Disposal requirements vary by country and by state.
• Lithium batteries are not listed by the Environmental Protection Agency (EPA) as a hazardous waste.
Therefore, they can typically be disposed of as normal waste.
• If you are disposing of large quantities, contact a local waste-management service.
• No hazardous compounds are used within the battery module.
• The weight of the lithium contained in each coin cell is approximately 0.035 grams.
• Two types of batteries are used interchangeably:
— CR chemistry uses manganese dioxide as the cathode material.
— BR chemistry uses poly-carbonmonofluoride as the cathode material.
