Cisco 3310 Mobility Services Engine Getting Started Guide
2-4
Do not spill food or liquids on your system components, and never operate the product in a wet
environment.
Do not push any objects into the openings of your system components. Doing so can cause fire or
electric shock by shorting out interior components.
Use the product only with other Cisco-approved equipment.
Use the correct external power source. Operate the product only from the type of power source
indicated on the electrical ratings label. If you are not sure of the type of power source required,
consult your service representative or local power company.
Use only Cisco approved power cables.
To help prevent electric shock, plug the system components and peripheral power cables into
properly grounded electrical outlets. These cables are equipped with three-prong plugs to help
ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable.
Observe power strip ratings. Make sure that the total ampere rating of all products plugged into the
power strip does not exceed 80 percent of the power strip ampere ratings limit.
To help protect your system components from sudden, transient increases and decreases in electrical
power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
Position cables and power cords carefully; route cables and the power cord and plug so that they
cannot be stepped on or tripped over. Be sure that nothing rests on your system components' cables
or power cord.
Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local or national wiring rules.
Do not try to open the product enclosure. There are no user-serviceable components inside.
Do not operate controls, make adjustments, or perform procedures on the laser device.
Allow only Cisco authorized service technicians to repair the laser device.
Two or more people are required to install the device in a rack.
Ensure that the room air temperature is below 95°F (35°C).
Do not block any air vents; usually 6 inches (15 cm) of space provides proper airflow.
Plan the device installation starting from the bottom of the rack.
Install the heaviest device in the bottom of the rack.
Do not extend more than one device out of the rack at the same time.
Remove the rack doors and side panels to provide easier access during installation.
Connect the device to a properly grounded outlet.
