Power Precautions; Preparing The Installation Site - Brocade Communications Systems ICX 6430 Installation Manual

Power precautions

CAUTION
Use a separate branch circuit for each AC 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
Disconnect the power cord from all power sources to completely remove power from the device.
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.

Preparing the installation site

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 in.]) on all sides for proper airflow.
Be accessible for installing, cabling, and maintaining the devices.
Allow the status LEDs to be clearly visible.
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.
Provide a separate grounded power outlet that provides 100 to 240 VAC, 50-60 Hz, is within
2.44 m (8 ft) of each device, and is powered from an independent circuit breaker.
As with any electrical equipment, a filter or surge suppressor is recommended.
