with an uncovered slot, the system will overheat.
CAUTION
Use the screws specified in the procedure. Using longer screws can damage the device.
CAUTION
Do not install the device in an environment where the operating ambient temperature might exceed 45°C (113°F).
CAUTION
Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the manufacturer’s
instructions.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megohm resistor.
CAUTION
Static electricity can damage the chassis and other electronic devices. To avoid damage, keep static-sensitive devices in
their static-protective packages until you are ready to install them.
CAUTION
Before plugging a cable into any port, be sure to discharge any static charge stored on the cable by touching the electrical
contacts to ground surface.
DANGER
If the installation requires a different power cord than the one supplied with the device, make sure you use a power cord
displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your
assurance that the power cord can be used safely with the device.

Safety Precautions
Lifting Precautions
Laser Precautions
DANGER
Disconnect the power cord from all power sources to completely remove power from the device.
DANGER
This device might have more than one power cord. To reduce the risk of electric shock, disconnect all power cords before
servicing.
CAUTION
To avoid high voltage shock, do not open the device while the power is on.
CAUTION
Use a separate branch circuit for each power cord, which provides redundancy in case one of the circuits fails.
CAUTION
Ensure that the device does not overload the power circuits, wiring, and over-current protection. To determine the
possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices installed on the same circuit as
the device. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the
devices near the input power connectors.
DANGER
Use safe lifting practices when moving the product.
DANGER
Mount the devices you install in a rack as low as possible. Place the heaviest device at the bottom and progressively
place lighter devices above.
CAUTION
Make sure the rack housing the device is adequately secured to prevent it from becoming unstable or falling over.
CAUTION
To prevent damage to the chassis and components, never attempt to lift the chassis using the fan or power supply
handles. These handles were not designed to support the weight of the chassis.
DANGER
All fiber-optic interfaces use Class 1 lasers.

Preparing for Installation
Facility Requirements
Facility Requirements
To install and operate the device successfully, ensure compliance with the following electrical, environmental, location, and cable
management requirements.
Electrical Considerations
For successful installation and operation of the device, ensure that the following electrical requirements are met:
•The primary outlet is correctly wired, protected by a circuit breaker, and grounded in accordance with local electrical codes.
•The supply circuit, line fusing, and wire size are adequate, as specified by the electrical rating on the device nameplate.
•The power supply standards are met.
Environmental Considerations
For successful installation and operation of the device, ensure that the following environmental requirements are met:
•Because the Ruckus ICX 7850 switch can be ordered with fans that move air either front to back or back to front, be sure to
orient your switch with the airflow pattern of any other devices in the rack. All equipment in the rack should force air in the same
direction to avoid intake of exhaust air.
•Some combinations of intake and exhaust airflows may not be compatible with your environment. Consult your fan assembly
and power supply module FRU kits to determine the correct configuration.
•The ambient air temperature does not exceed 45°C (113°F).
Location Considerations
Before installing the device, plan its location and orientation relative to other devices and equipment. Devices can be mounted in a
standard 19-inch equipment rack or on a flat horizontal surface.
The site should meet the following requirements:
•Maintain the operating environment as specified in “Environmental Considerations” on page 10.
•Allow a minimum of 7.62 cm (3 in.) of space between the front and the back of the device and walls or other obstructions for
proper airflow.
•Allow at least 7.62 cm (3 in.) of space at the front and back of the device for the twisted-pair, fiber-optic, and power cabling.
•Allow access space for installing, cabling, and maintaining the devices.
•Ensure the status LEDs are clearly visible.
DANGER
Laser radiation. Do not view directly with optical instruments. Class 1M laser products.
DANGER
Use only optical transceivers that are qualified by Ruckus and comply with the FDA Class 1 radiation performance
requirements defined in 21 CFR Subchapter I, and with IEC 60825 and EN60825. Optical products that do not comply
with these standards might emit light that is hazardous to the eyes.
