v You do not operate the server without the air baffles installed. Operating theserver without the air baffles might cause the microprocessor to overheat.Handling static-sensitive devicesAttention: Static electricity can damage the server and other electronic devices. Toavoid damage, keep static-sensitive devices in their static-protective packages untilyou are ready to install them.To reduce the possibility of damage from electrostatic discharge, observe thefollowing precautions:v Limit your movement. Movement can cause static electricity to build up aroundyou.v Handle the device carefully, holding it by its edges or its frame.v Do not touch solder joints, pins, or exposed 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 unpaintedmetal part on the outside of the server for at least 2 seconds. This drains staticelectricity from the package and from your body.v Remove the device from its package and install it directly into the serverwithout setting down the device. If it is necessary to set down the device, put itback into its static-protective package. Do not place the device on the servercover or on a metal surface.v Take additional care when handling devices during cold weather. Heatingreduces indoor humidity and increases static electricity.Returning a device or componentIf you are instructed to return a device or component, follow all packaginginstructions, and use any packaging materials for shipping that are supplied toyou.Removing and replacing server componentsThis section provides information for removing and replacing components in theserver.Removing and replacing consumable parts and Tier 1 CRUsReplacement of consumable parts and Tier 1 CRUs is your responsibility.
