Power precautions
Use a separate branch circuit for each AC power cord, which provides 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 chassis. 
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.
