eServer 326m Type 7969: Installation Guide
Suggested 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.
Notes:
1. To prevent diskette drive read/write errors, make sure that the distance
between the monitor 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.
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.
Suggested 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.

program. Whenever memory or an option is changed, you must update the
configuration.
If the problem remains, call for service.
v Make sure that all of the option hardware and cable connections are secure.
v If the option comes with test instructions, use those instructions to test the
option.
v If the failing option is a SCSI device, make sure that:
– The cables for all external SCSI options are connected correctly.
– The last device in each SCSI chain, or the end of the SCSI cable, is
terminated correctly.
– Any external SCSI devices are turned on. You must turn on external SCSI
devices before turning on the server.
