2.2 Environmental and Power Requirements
In order to meet the environmental requirements, the blade must be tested in the system in
which it is to be installed.
Before you power up the blade, calculate the power needed according to the combination of
blade upgrades and accessories.
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 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.
Blade Surface and Blade Damage
High humidity and condensation on the blade surface causes short circuits.
Do not operate the blade outside the specified environmental limits. Make sure that 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 the forced air cooling is available on the shelf.
