Monitor problems ✏ NOTE The monitor screen remains blank until it is directed to a blade server that is powered on; this is normal behavior. Symptom Suggested action The monitor screen goes blank when you direct it to a working blade server, or it goes blank when you start some application programs in the blade servers. Make sure that the monitor cable is connected to the video port on the management module. If you still cannot find the problem, try using the monitor with another blade server. If the problem persists, see the Intel Blade Server Chassis SBCE Hardware Maintenance Manual and Troubleshooting Guide on the Resource CE that came with your SBCE unit. The screen is blank. Make sure that: • The keyboard/mouse/video select button LED on the front of the blade server is lit, indicating that the blade server is connected to the shared monitor. • The SBCE unit power cord is connected to the power module and a working electrical outlet. • The monitor cables are connected properly. • The monitor is turned on and the brightness and contrast controls are adjusted correctly. 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 enabled (its default setting), you must restart the blade server three times to force the system BIOS to reset the Configuration settings to the default configuration (memory connector or bank of connectors enabled) Only the cursor appears. Make sure that the keyboard, video, and mouse on the SBCE unit have not been switched to another blade server. The monitor has screen jitter, or the screen image is wavy, unreadable, rolling, or distorted. If the monitor self-tests show that the monitor is working correctly, consider the location of the monitor. Magnetic fields around other devices (such as transformers, appliances, fluorescent lights, and other monitors) can cause screen jitter or wavy, unreadable, rolling, or distorted screen images. If this happens, turn off the monitor. Attention: Moving a color monitor while it is turned on might cause screen discoloration. Move the device and the monitor at least 300 mm (12 in.) apart, and turn on the monitor. ✏ NOTE To prevent diskette drive read/write errors, make sure the distance between the monitor and diskette drives is at least 75 mm (3 in.). Wrong characters appear If the wrong language is displayed, update the firmware or operating system with on the screen. the correct language in the blade server that has ownership of the monitor. 62 Intel Server Compute Blade SBX82 Installation and User's Guide
