IBM® Netfinity® 6000R User’s Reference
The monitor works when
you turn on the server, but
goes blank when you start
some application programs. Verify that:
1. The primary monitor cable is connected to the video port.
2. You installed the necessary device drivers for the applications.
If the items above are correct and the screen remains blank, call for service.
Wavy, unreadable, rolling,
distorted screen, or screen
jitter. If the monitor self-tests show the monitor is OK, 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. (Moving a color monitor while it is turned on might cause
screen discoloration.) Then move the device and the monitor at least 305 mm
(12 in.) apart. Turn on the monitor.
Notes:
1. To prevent diskette drive read/write errors, be sure the distance
between monitors and diskette drives is at least 76 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, see your IBM reseller or IBM marketing representative.
If the problem remains, call for service.
Wrong characters appear on
the screen. If the wrong language is displayed, update the BIOS with the correct
language.
If the problem remains, call for service.
Option problems Verify that:
1. The option is designed for the server. Refer to the "Support for Netfinity
Servers" flowchart for information about obtaining ServerProven™
compatibility information from the World Wide Web.
2. You followed the installation instructions that came with the option.
3. The option is installed correctly.
4. You have not loosened any other installed options or cables.
