Installation guidelines Important: 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 "Solving Problems" in the Installation Guide for diagnostic information. Before you install optional devices, read the following information: v Read the safety information that begins on page v, the guidelines in "Working inside the server with the power on" on page 22, and "Handling static-sensitive devices" on page 23. 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. 20 System x3200 M2 Types 4367 and 4368: User's Guide
