CAUTION: The power supply switch must be in the off position when you
insert the power supply into the chassis. Damage to the switch can result if
a live power supply is installed.
CAUTION: Carefully follow the mechanical guides on each side of the
power supply slot and make sure the power supply is properly inserted in
the guides. Never insert the power supply upside down.
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.
DANGER: Make sure the rack housing the device is adequately secured to
prevent it from becoming unstable or falling over.
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.
Laser precautions
DANGER: All fiber-optic interfaces use Class 1 lasers.
DANGER: Use only optical transceivers that are qualified by IBM and
comply with the FDA Class 1 radiation performance requirements defined
in 21 CFR Subchapter I, and with IEC 825 and EN60825. Optical products
that do not comply with these standards might emit light that is hazardous
to the eyes.
Safety labels
As an added precaution, safety labels are often installed directly on products or product components to
warn of potential hazards. These can be either danger or caution notices, depending upon the level of the
hazard.
The actual product safety labels may differ from these sample safety labels:
