Hardware acclimation times

Units must acclimate to the operating environment before applying power. This requires the
unpackaged system or component to reside in the operating environment for up to 16 hours in
order to thermally stabilize and prevent condensation.

Before touching any unit, touch a bare (unpainted) metal surface of the cabinet/rack or
enclosure.
Before removing any unit from its antistatic bag, place one hand firmly on a bare metal surface
of the cabinet/rack or enclosure, and at the same time, pick up the unit while it is still sealed in
the antistatic bag. At the same time, do not move around the room or touch other furnishings,
personnel, or surfaces until you have installed the unit.
When you remove a unit from the antistatic bag, avoid touching any electronic components
and circuits on it.
If you must move around the room or touch other surfaces before installing a unit, first place
the unit back in the antistatic bag. When you are ready again to install the unit, repeat these
procedures.

If there are signs of condensation after the recommended acclimation time has passed, allow
an additional eight (8) hours to stabilize.
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).
