Preparing for the Installation
Warning
This device might have more than one power cord. To reduce the risk of electric shock,
disconnect all power cords before servicing.
Warning
To avoid high voltage shock, do not open the device while the power is on.
Caution
Use a separate branch circuit for each 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.
Lifting precautions
Warning
Use safe lifting practices when moving the product.
Warning
Mount the devices you install in a rack as low as possible. Place the heaviest device at the
bottom and progressively place lighter devices above.
Warning
Make sure the rack housing the device is adequately secured to prevent it from becoming
unstable or falling over.
Caution
To prevent damage to the chassis and components, never attempt to lift the chassis using the
fan or power supply handles. These handles were not designed to support the weight of the
chassis.
Laser precautions
