Table 15 Hardware acclimation times (systems and components) (continued)
If the last 24 hours of the
TRANSIT/STORAGE
environment was this:
Unknown
NOTICE
If there are signs of condensation after the recommended acclimation time has
l
passed, allow an additional eight (8) hours to stabilize.
Systems and components must not experience changes in temperature and
l
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).
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
For a module that must be installed into a slot in an enclosure, examine the rear
l
connectors on the module for any damage before attempting its installation.
A sudden jar, drop, or even a moderate vibration can permanently damage some
l
sensitive replaceable units.
Do not remove a faulted replaceable unit until you have the replacement available.
l
When handling replaceable units, avoid electrostatic discharge (ESD) by wearing
l
ESD anti-static gloves or an ESD wristband with a strap. For additional
information, refer to
Avoid touching any exposed electronic components and circuits on the replaceable
l
unit.
Never use excessive force to remove or install a replaceable unit. Take time to
l
read the instructions carefully.
Store a replaceable unit in the antistatic bag and the specially designed shipping
l
container in which you received it. Use the antistatic bag and special shipping
container when you need to return the replaceable unit.
Replaceable units must acclimate to the operating environment before applying
l
power. This requires the unpackaged component to reside in the operating
...and the OPERATING
environment is this:
<86°F (30°C)
Avoiding electrostatic discharge (ESD) damage
...then let the system
or component
acclimate in the new
environment this many
hours:
