IBM xSeries 345 Type 8670: Installation Guide
Suggested action
Call for service.
Verify that you installed the necessary device drivers for the application.
If the items above are correct and the screen remains blank, call for service.
If the monitor self-tests show the monitor is working properly, 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, contact
your IBM reseller or IBM marketing representative.
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.
Verify that:
v The option is designed for the server. See the "Server Support" flowchart for
information about obtaining ServerProven
World Wide Web.
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 remains, call for service.
Verify that all of the option hardware and cable connections are secure.
If the option comes with its own test instructions, use those instructions to test the
option.
If the failing option is a SCSI option, verify that:
v The cables for all external SCSI options are connected correctly.
v The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.
v Any external SCSI option is turned on. You must turn on an external SCSI option
before turning on the server.
If the problem remains, call for service.
