Note: See "System replaceable units" on page 144 to determine which components should be replaced by a field service technician. Symptom FRU/action The screen is blank. 1. Verify that: v The server power cord is connected to the server and a working electrical outlet. v The monitor cables are connected properly. v The monitor is turned on and the brightness and contrast controls are adjusted correctly. v If the servers are C2T chained together, verify that: - The C2T chain cables are securely connected to the servers. - The C2T breakout cable is connected properly. - A server that is turned on is selected. Important: In some memory configurations, the 3-3-3 beep code might sound during POST followed by a blank display screen. If this occurs and the Boot Fail Count feature in the Start Options of the Configuration/Setup Utility program is set to Enabled (its default setting), you must restart the server three times to force the system BIOS to reset the CMOS values to the default configuration (memory connector or bank of connectors enabled). If you have installed a Remote Supervisor Adapter II SlimLine in the server, make sure that the video cable is connected to the Remote Supervisor Adapter II SlimLine. 2. Verify that the memory is installed (see "Installing memory modules" on page 33) and configured (see "Starting the Configuration/Setup Utility program" on page 9) correctly. 3. Make sure that damaged BIOS code is not affecting the video; see "Recovering the BIOS code" on page 97. 4. If you have verified these items and the screen remains blank, replace: a. Monitor b. Video adapter, if installed c. System board Only the cursor appears. v See "Undetermined problems" on page 140 The monitor works when you turn on the server but goes blank when you start some application programs. 1. Verify that: v The application program is not setting a display mode higher than the capability of the monitor. v The primary monitor cable is connected to the C2T device breakout cable. v You installed the necessary device drivers for the applications. 2. If you have verified these items and the screen remains blank, replace the monitor. Chapter 6. Symptom-to-FRU index 127
