Installation guidelinesAttention: Static electricity that is released to internal server components whenthe server is powered-on might cause the system to halt, which might result in theloss of data. To avoid this potential problem, always use an electrostatic-dischargewrist strap or other grounding system when removing or installing a hot-swapdevice.Before you install optional devices, read the following information:v Make sure that the devices that you are installing are supported. For a list ofsupported optional devices for the server, see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.v Read the safety information that begins on page vii and the guidelines in“Working inside the server with the power on” on page 39, and “Handlingstatic-sensitive devices” on page 39. This information will help you work safely.v When you install your new server, take the opportunity to download and applythe most recent firmware updates. This step will help to ensure that any knownissues are addressed and that your server is ready to function at maximum levelsof performance. To download firmware updates for your server, go tohttp://www.ibm.com/support/fixcentral/.Important: Some cluster solutions require specific code levels or coordinatedcode updates. If the device is part of a cluster solution, verify that thelatest level of code is supported for the cluster solution before youupdate the code.For additional information about tools for updating, managing, and deployingfirmware, see the ToolsCenter for System x and BladeCenter athttp://publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp.v Before you install optional hardware, make sure that the server is workingcorrectly. Start the server, and make sure that the operating system starts, if anoperating system is installed, or that a 19990305 error code is displayed,indicating that an operating system was not found but the server is otherwiseFigure 4.
