Device Suggested action
The screen is wavy,
unreadable, rolling, distorted,
or has screen jitter. 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.
Wrong characters appear on
the screen. If the wrong language is displayed, update the firmware in the management module
with the correct language.
If the problem remains, call for service.
Power
The system does not power
on. Verify that:
1. The power cables are properly connected to the power modules in the
BladeCenter unit.
2. The 220-volt PDU or electrical outlet functions properly.
3. The LEDs on the power module are on.
4. If you just installed an option, remove it, and restart the BladeCenter unit. If the
BladeCenter unit now turns on, you might have installed more options than the
power module supports. You might need to install a power module in power bay 3
or 4.
If the problem remains, call for service.
Option problems
An IBM option that was just
installed does not work. Verify that:
v The option is designed for the BladeCenter unit. See the “Server Support”
flowchart on the inside of the front cover for information about obtaining
ServerProven
®
compatibility information from the 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.
If the problem remains, call for service.
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 problem remains, call for service.
Service processor problems
Service processor in the
management module reports
a general monitor failure. Disconnect the BladeCenter unit from all electrical sources, wait for 30 seconds,
reconnect the BladeCenter unit to the electrical sources, and restart the server.
If a problem remains, call for service.
