Requirements
In order to meet the environmental requirements, the blade has to be tested in the system in which it is to be installed.a
Before you power up the blade, calculate the power needed according to your combination of blade upgrades and accessories.
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.aaa
Note:a
SThe 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
SOperating temperatures refer to the temperature of the air circulating around the blade and not to the actual component temperature.
SBlade 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. Do not operate the blade below 0°C.
SBlade 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.
