IBM® xSeries 360: 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 these items 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 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 remains, call for service.
Wrong characters appear on the
screen. If the wrong language is displayed, update the BIOS code with the correct
language.
If the problem remains, call for service.
Option problems Verify that:
1. The server supports the option. Refer to the "Server Support" flowchart for
information about obtaining ServerProven compatibility information from the
World Wide Web.
2. You followed the installation instructions that come with the option.
3. The option is installed correctly.
4. You have not loosened any other installed options or cables.
5. You updated the configuration information using the Configuration/Setup
Utility program. Whenever memory or an option is changed, you must
update the configuration.
If the problem remains, call for service.
An IBM option that you just installed
does not work.
An IBM option that used to work
does not work now. 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:
1. The cables for all external SCSI options are connected correctly.
2. The last option in each SCSI chain, or the end of the SCSI cable, is
terminated correctly.
3. 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.
