Lifting And Weight-Related Precautions - IBM 8960-F64 Hardware Installation Manual

Lifting and weight-related precautions

DANGER
Disconnect the power cord from all power sources to completely remove power from the device.
DANGER
To avoid high voltage shock, do not open the device while the power is on.
DANGER
Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according
to the instructions.
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.
CAUTION
All devices with AC power sources are intended for installation in restricted access areas only.
A restricted access area is a location where access can be gained only by service personnel
through the use of a special tool, lock and key, or other means of security.
Lifting and weight-related precautions
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
Do not use the port cover tabs to lift the module. They are not designed to support the weight of
the module, which can fall and be damaged.
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.
