Chapter 4. Removing and replacing server components Replaceable components are of three types: v Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If IBM installs a Tier 1 CRU at your request, you will be charged for the installation. v Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or request IBM to install it, at no additional charge, under the type of warranty service that is designated for your server. v Field replaceable unit (FRU): FRUs must be installed only by trained service technicians. See Chapter 3, "Parts listing, System x3200 M2 Types 4367 and 4368," on page 33 to determine whether a component is a Tier 1 CRU, Tier 2 CRU, or FRU. For information about the terms of the warranty and getting service and assistance, see the Warranty and Support Information document. For additional information and important notes about installing options in the server, see the specific options section in the User's Guide on the System x Documentation CD. Installation guidelines Before you remove or replace a component, read the following information: v Read the safety information that begins on page vii and the guidelines in "Handling static-sensitive devices" on page 50. This information will help you work safely. v When you install your new server, take the opportunity to download and apply the most recent firmware updates. This step will help to ensure that any known issues are addressed and that your server is ready to function at maximum levels of performance. To download firmware updates for your server, complete the following steps. Note: Changes are made periodically to the IBM Web site. The actual procedure might vary slightly from what is described in this document. 1. Go to http://www.ibm.com/systems/support/. 2. Under Product support, click System x. 3. Under Popular links, click Software and device drivers. 4. Click IBM System x3200 M2 to display the matrix of downloadable files for the server. For additional information about tools for updating, managing, and deploying firmware, see the System x and xSeries Tools Center at http:// publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp v Before you install optional hardware devices, make sure that the server is working correctly. Start the server, and make sure that the operating system starts, if an operating system is installed, or that a 19990305 error code is displayed, indicating that an operating system was not found but the server is otherwise working correctly. If the server is not working correctly, see Chapter 5, "Diagnostics," on page 121 for more information. v Observe good housekeeping in the area where you are working. Place removed covers and other parts in a safe place. © Copyright IBM Corp. 2008 47
