Table 1 Hardware acclimation times (systems and components) (continued)
If the last 24 hours of the
TRANSIT/STORAGE
environment was this:
…and the OPERATING
environment is this:
…then let the system
or component
acclimate in the new
environment this many
hours:
Hot
>72°F (22°C)
Dry
<30% RH
<86°F (30°C) 4 hours
Hot
>72°F (22°C)
Humid
30-45% RH
<86°F (30°C) 4 hours
Humid
45-60% RH
<86°F (30°C) 8 hours
Humid
≥60% RH
<86°F (30°C) 16 hours
Unknown <86°F (30°C) 16 hours
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
the table, Table 1 on page 5. 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:
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.
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.
