Chapter 6. Solving problems This chapter provides basic information about the diagnostic tools that are available to help you solve some common problems that might occur while you are setting up the blade server. If you install the blade server in the BladeCenter unit and the blade server does not start, perform the following actions: v Make sure that the BladeCenter unit is correctly connected to a power source. v Reseat the blade server in the BladeCenter unit (see "Installing the blade server in a BladeCenter unit" on page 36). v If the power-on LED is flashing slowly, turn on the blade server (see "Turning on the blade server" on page 11). v If you have just added a new optional device or component, make sure that it is correctly installed and compatible with the blade server and its components. If the device or component is not compatible, remove it from the blade server, reinstall the blade server in the BladeCenter unit, and then restart the blade server. If the blade server does not start after you have performed the preceding actions, see the Problem Determination and Service Guide for your blade server on the IBM Documentation CD. Diagnostic tools overview The following tools are available to help you diagnose and solve hardware-related problems: v POST beep codes The power-on self-test beep codes can indicate the detection of a problem. - One beep indicates successful completion of POST - Repeating long beeps indicate a memory error. Make sure that all DIMMs are correctly installed. - Additional beep codes are listed in "Diagnostics" in the Problem Determination and Service Guide for your blade server. v POST error codes The POST error codes indicate the detection of a problem. See the Problem Determination and Service Guide for more information. v ServerGuide problems The table in "ServerGuide problems" on page 52 lists problem symptoms and steps to correct the problems. v Troubleshooting tables Use the troubleshooting tables to find solutions to problems that have identifiable symptoms.
