System reliability guidelines To help ensure proper cooling and system reliability, make sure that: v The ventilation holes on the blade server are not blocked. v Each of the blade bays on the front of the BladeCenter unit has a blade server or filler blade installed. Do not operate the BladeCenter unit for more than 1 minute without a blade server or filler blade installed in each blade bay. v You have followed the reliability guidelines in the documentation that comes with the BladeCenter unit. Handling static-sensitive devices Attention: Static electricity can damage electronic devices and your system. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them. To reduce the possibility of electrostatic discharge, observe the following precautions: v Limit your movement. Movement can cause static electricity to build up around you. v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed printed circuitry. v Do not leave the device where others can handle and damage it. v While the device is still in its static-protective package, touch it to an unpainted metal part of the BladeCenter chassis for at least 2 seconds. This drains static electricity from the package and from your body. v Remove the device from its package and install it directly into the blade server or BladeCenter unit without setting the device down. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the blade server cover or on a metal surface. v Take additional care when handling devices during cold weather. Heating reduces indoor humidity and increases static electricity. v Wear an electrostatic-discharge wrist strap, if one is available. 30 BladeCenter QS21 Type 0792: Problem Determination and Service Guide
