NOTICE
l
If there are signs of condensation after the recommended acclimation time has
passed, allow an additional eight (8) hours to stabilize.
l
Systems and components must not experience changes in temperature and
humidity that are likely to cause condensation to form on or in that system or
component. Do not exceed the shipping and storage temperature gradient of
45°F/hr (25°C/hr).
l
Do NOT apply power to the system for at least the number of hours specified in
on page 123. If the last 24 hours of the transit/storage environment is
unknown, then you must allow the system or component 16 hours to stabilize in
the new environment.
Removing, installing, or storing replaceable units
Use the following precautions when removing, handling, or storing replaceable units:
CAUTION
Some replaceable units have the majority of their weight in the rear of the
component. Ensure that the back end of the replaceable unit is supported while
installing or removing it. Dropping a replaceable unit could result in personal
injury or damage to the equipment.
NOTICE
l
For a module that must be installed into a slot in an enclosure, examine the rear
connectors on the module for any damage before attempting its installation.
l
A sudden jar, drop, or even a moderate vibration can permanently damage some
sensitive replaceable units.
l
Do not remove a faulted replaceable unit until you have the replacement available.
l
When handling replaceable units, avoid electrostatic discharge (ESD) by wearing
ESD anti-static gloves or an ESD wristband with a strap. For additional
information, refer to
Avoiding electrostatic discharge (ESD) damage
l
Avoid touching any exposed electronic components and circuits on the replaceable
unit.
l
Never use excessive force to remove or install a replaceable unit. Take time to
read the instructions carefully.
l
Store a replaceable unit in the antistatic bag and the specially designed shipping
container in which you received it. Use the antistatic bag and special shipping
container when you need to return the replaceable unit.
l
Replaceable units must acclimate to the operating environment before applying
power. This requires the unpackaged component to reside in the operating
environment for up to 16 hours in order to thermally stabilize and prevent
condensation. Refer to
replaceable unit has thermally stabilized to the operating environment.
