Facility Requirements

General

• The site should be accessible for installing, cabling, and maintaining the devices.
• Maintain the operating environment as specified in the Technical Specifications.
• Allow at least 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 the status LEDs to be clearly visible.
• Allow for the unit to be connected to a separate grounded power outlet that provides 100 to 240 VAC, 50/60 Hz, within 2 m (6.6 ft) of each device, and is powered from an independent circuit breaker. As with any equipment, a filter or surge suppressor is recommended.
• Allow for twisted-pair cables to be routed away from power lines, fluorescent lighting fixtures, and other sources of electrical interference, such as radios and transmitters.

Electrical

• Adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on the switch nameplate
• Circuit protected by a circuit breaker and grounded in accordance with local electrical codes

For complete power supply specifications, refer to RUCKUS ICX 7550 Switch Technical Specifications.

Thermal

• A minimum airflow of 39.1 cubic meters/hour (23 cubic ft/min.) available in the immediate vicinity of the switch
  Note: Although this airflow may exceed the airflow maximum listed in the device Technical Specifications, the additional airflow is recommended to pressurize the inlet (cool isle) side of rack installations relative to the exhaust side to minimize recirculation of hot air back to the inlet side.
• Ambient air temperature not exceeding 45°C (113°F) while the switch is operating

Rack (when rack-mounted)

• One rack unit (1U) in a 48.3 cm (19-inch) rack
• All equipment in the rack grounded through a reliable branch circuit connection
• Additional weight of switch must not exceed the weight limits of the rack
• Temperature: Because the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range.
• Airflow: Be sure that the airflow direction for all equipment in a rack is the same or consistent.
• Mechanical loading: Do not place any equipment on top of a rack-mounted unit.
• Rack secured to ensure stability in case of unexpected movement.
• Circuit overloading: Be sure that the supply circuit to the rack assembly is not overloaded.
