Hardware Preparation and Installation
2.2.1 Environmental Requirements
The environmental conditions must be tested and proven in the shelf configuration used.
The conditions refer to the surrounding of the blade within the user environment.
The environmental requirements of the blade may be further limited down due to
installed accessories, such as hard disks or PMC modules, with more restrictive
environmental requirements.
Operating temperatures refer to the temperature of the air circulating around the
blade and not to the actual component temperature.
NOTICE
Blade Damage - Blade surface
High humidity and condensation on the blade surface causes short circuits.
Do not operate the blade outside the specified environmental limits. Make sure the
blade is completely dry and there is no moisture on any surface before applying
power.
Blade Overheating and Blade Damage
Operating the blade without forced air cooling may lead to blade overheating and
thus blade damage.
When operating the blade, make sure that forced air cooling is available in the shelf.
