Installing a redundant power supply

DRAFT: BROCADE CONFIDENTIAL
Selecting a redundant power supply installation site
RPS2-EIF and RPS12 power supplies can be mounted in a standard 19-inch equipment rack or on
a flat surface. Be sure to follow these guidelines when choosing a location.
Do not place a redundant power supply on the floor as the case is not waterproof. It is
recommended that either of the redundant power supplies be installed in a network equipment
rack.
Remove the power cord from a power supply before you install it in or remove it from the device.
Otherwise, the power supply or the device could be damaged as a result. (The device can be
running while a power supply is being installed or removed, but the power supply itself should not
be connected to a power source.)
The installation site should meet these requirements:
• Be at the center of all the devices you want to link, and near a power outlet.
• Maintain temperatures within 0 to 40 °C (32 to 104 °F) and humidity levels within 5% to 95%,
non-condensing.
• Provide adequate space (approximately 5.08 cm (2 inches) on all sides for proper air flow.
• Be accessible for installing, cabling and maintaining the devices.
• Allow the status LEDs to be clearly visible.
• Allow for twisted-pair cable to be always routed away from power lines, fluorescent lighting
fixtures and other sources of electrical interference, such as radios and transmitters.
• Provide a separate grounded power outlet that provides 100 to 240 VAC, 50-60 Hz, is within
2.44 m (8 feet) of each device, and is powered from an independent circuit breaker.
• As with any electrical equipment, a filter or surge suppressor is recommended.
