IBM Eserver xSeries Appliances: Installation Guide for xSeries Hosting Appliance
Table 4. Troubleshooting charts (continued)
Device
Wavy, unreadable, rolling,
distorted screen, or screen
jitter.
Wrong characters appear on
the screen.
Option problems
An IBM option that was just
installed does not work.
Power problems
The xSeries Hosting Appliance
does not power on.
Suggested Action
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. (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
that 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 IBM model 9521 and 9527
monitors. For information about the enhanced monitor
cable, see your IBM reseller or IBM marketing
representative.
If the problem continues, call for service.
If the wrong language is displayed, update the BIOS code
with the correct language. If the problem continues, call
for service.
Verify that:
v The option is designed for the xSeries Hosting
Appliance. Refer to http://www.ibm.com/us/compat.
v You followed the installation instructions that came
with the option.
v The option is installed correctly.
v You have not loosened any other installed options or
cables.
v You 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 continues, call for service.
Verify that:
v The power cables are properly connected to the xSeries
Hosting Appliance.
v The electrical outlet functions properly.
v The type of memory installed is correct.
v If you just installed an option, remove it, and restart the
server. If the server now powers on, you might have
installed more options than the power supply supports.
If the problem continues, call for service.
