Power Precautions - Brocade Communications Systems MLX Series Installation Manual

Power precautions

Use a separate branch circuit for each AC power cord for redundancy in case one of the circuits fails.
Make sure to choose the appropriate circuit device, depending on the number of AC power supplies
installed in the device.
Disconnect the power cord from all power sources to completely remove power from the device.
Make sure that the power source circuits are properly grounded, then use the power cord supplied with
the device to connect it to the power source.
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.
Make sure the rack or cabinet housing the device is adequately secured to prevent it from becoming
unstable or falling over.
Mount the devices you install in a rack or cabinet as low as possible. Place the heaviest device at the
bottom and progressively place lighter devices above.
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.
