Symptom
An IBM option that was just
installed does not work.
Action
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: Non-IBM monitor cables might cause unpredictable problems.
If the problem remains, call for service.
If the wrong language is displayed, update the BIOS code with the correct
language.
If the problem remains, call for service.
Action
Make sure that:
v The option is designed for the server. See the "Server Support" flowchart for
information about obtaining ServerProven compatibility information from the
World Wide Web.
v You followed the installation instructions that come with the option.
v The option is installed correctly.
v You have not loosened any other installed options or cables.
v You have updated the configuration information in the Configuration/Setup Utility
program. Whenever memory or an option is changed, you must update the
configuration.
If the problem remains, call for service.
