Before you place the computer in an upright position, rotate the two front feet a quarter turn away from the computer, see "Installing options in a tower model" on page 44 for details. v Back up all important data before you make changes to hard disk drives. v Have a small, flat-blade screwdriver available. v For a list of supported options for your computer, refer to http://www.ibm.com/pc/support on the World Wide Web. System reliability considerations To help ensure proper cooling and system reliability, make sure that: v Each of the drive bays has a drive or a filler panel and electromagnetic compatibility (EMC) shield installed. v There is space around the computer to allow the computer cooling system to work properly. Leave about 127 mm (5 in.) of space around the front and rear of the computer. v Cables for optional adapters are routed according to the instructions that are provided with the adapters. v A failed fan is replaced within 1 hour. 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 bag 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 possibly damage the device. v While the device is still in its anti-static package, touch it to an unpainted metal part of the system unit for at least two seconds. (This drains static electricity from the package and from your body.) v Remove the device from its package and install it directly into your system unit without setting it down. If it is necessary to set the device down, place it on its static-protective package. (If your device is an adapter, place it component side up.) Do not place the device on your system unit cover or on a metal table. v Take additional care when handling devices during cold weather as heating reduces indoor humidity and increases static electricity. 38 IBM® IntelliStation® E Pro: User's Guide IntelliStation E Pro Types 6836, 6846
