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 10. 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.
Avoiding electrostatic discharge (ESD) damage
When replacing or installing hardware units, you can inadvertently damage the
sensitive electronic circuits in the equipment by simply touching them. Electrostatic
charge that has accumulated on your body discharges through the circuits. If the air in
the work area is very dry, running a humidifier in the work area will help decrease the
risk of ESD damage. Follow the procedures below to prevent damage to the
equipment.
Be aware of the following requirements:
l
Provide enough room to work on the equipment.
