v Do not drop any metallic objects, such as paper clips, hairpins, and screws, into the server. Handling static-sensitive devices Attention: Static electricity can damage the server and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them. To reduce the possibility of damage from electrostatic discharge, observe the following precautions: v Limit your movement. Movement can cause static electricity to build up around you. v The use of a grounding system is recommended. For example, wear an electrostatic-discharge wrist strap, if one is available. Always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on 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 unpainted metal surface on the outside of the server 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 server without setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the 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. Removing the cover Attention: Operating the server for more than 2 minutes with the top cover removed might damage server components. For proper cooling and airflow, replace the top cover before you turn on the server. To remove the cover, complete the following steps: 1. Read the safety information that begins on page v and "Installation guidelines" on page 9. 2. If you are planning to install or remove a microprocessor, memory module, PCI adapter, or tape drive, turn off the server and all attached devices and disconnect all external cables and power cords (see "Turning off the server" on page 37). 3. Press down on the left and right side latches and pull the server out of the rack enclosure until both slide rails lock. Note: You can reach the cables on the back of the server when the server is in the locked position. Chapter 2. Installing optional devices 11
