Important Safety Instructions,
• Safety Checks - After service, assemble this equipment and perform safety checks to
ensure it is safe to use before putting it back into operation.
Electrostatic Discharge
Electrostatic discharge (ESD) results from the static electricity buildup on the human body
and other objects. This static discharge can degrade components and cause failures.
Take the following precautions against electrostatic discharge:
• Use an anti-static bench mat and a wrist strap or ankle strap designed to safely ground
ESD potentials through a resistive element.
• Keep components in their anti-static packaging until installed.
• Avoid touching electronic components when installing a module.
Fuse Replacement
To replace a fuse, comply with the following:
• Disconnect the power before changing fuses.
• Identify and clear the condition that caused the original fuse failure.
• Always use a fuse of the correct type and rating. The correct type and rating are indicated
on this equipment.
Lithium Battery
For equipment with a lithium battery, observe the following rules:
• Do not dispose of used batteries through the regular garbage collection system, but follow
the local regulations. The batteries may contain substances that could be harmful to the
environment.
• Replace batteries with the same or equivalent type recommended by Cisco.
• Insert batteries correctly. There may be a risk of explosion if the batteries are incorrectly
inserted.
• When disposing of this equipment, remove the batteries and dispose of them separately
in accordance with local regulations.
• Do not recharge the batteries or expose them to temperatures above 100°C (212°F).
Electromagnetic Compatibility Regulatory Requirements
This equipment meets applicable electromagnetic compatibility (EMC) regulatory
requirements. EMC performance is dependent upon the use of correctly shielded cables of
good quality for all external connections, except the power source, when installing this
equipment.
• Ensure compliance with cable/connector specifications and associated installation
instructions where given elsewhere in this manual.
Otherwise, comply with the following good practices:
• Multi-conductor cables should be of single-braided, shielded type and have conductive
connector bodies and backshells with cable clamps that are conductively bonded to the
backshell and capable of making 360° connection to the cable shielding. Exceptions from
this general rule will be clearly stated in the connector description for the excepted
connector in question.
• Ethernet cables should be of single-shielded or double-shielded type.
• Coaxial cables should be of the double-braided shielded type.
