xSeries 206 Type 8482: Installation Guide
Suggested action
Make sure that:
v The server power cord is plugged into the server and a working electrical outlet.
v The monitor cables are connected correctly.
v The monitor is turned on and the brightness and contrast controls are adjusted
correctly.
v Make sure that the correct server is selected, if applicable.
Important: In some memory configurations, the 3-3-3 beep code might sound
during POST, followed by a blank monitor 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 server three times to force the
BIOS to reset the configuration settings to the default configuration (memory
connector or bank of connectors enabled).
If the problem remains, call for service.
Call for service.
If the monitor self-tests show 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.
Then move the device and the monitor at least 300 mm (12 in.) apart, and turn on
the monitor.
Notes:
1. To prevent diskette drive read/write errors, make sure that the distance
between monitors and diskette drives is at least 75 mm (3 in.).
2. Non-IBM monitor cables might cause unpredictable problems.
3. An enhanced monitor cable with additional shielding is available for the 9521
and 9527 monitors. For information about the enhanced monitor cable, contact
your IBM marketing representative or authorized reseller.
