Preparing for Installation
Safety Precautions
Lifting Precautions
Laser Precautions
DANGER
Disconnect the power cord from all power sources to completely remove power from the device.
DANGER
This device might have more than one power cord. To reduce the risk of electric shock, disconnect all power cords before
servicing.
CAUTION
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.
DANGER
Use safe lifting practices when moving the product.
DANGER
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.
CAUTION
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.
DANGER
All fiber-optic interfaces use Class 1 lasers.
