Mouse Problems
The monitor has screen
jitter, or the screen image
is wavy, unreadable,
rolling, or distorted. 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.
NOTE: 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.).
If the problem remains, call for service.
Wrong characters appear
on the screen. If the wrong language is displayed, update the firmware or operating system with
the correct language in the blade server that has ownership of the monitor.
If the problem remains, call for service.

The mouse does not work.
•
Make sure that the KVM select button LED on the front of the blade server
is lit, indicating that the blade server is connected to the shared mouse.
•
Make sure that the mouse cable is securely connected to the management
module and that the keyboard and mouse cables are not reversed.
•
Make sure that the mouse works correctly with other blade servers.
•
Make sure that the mouse is recognized as a USB device, not PS/2, by the
blade server. Although the mouse might be a PS/2-style device,
communication with the mouse is through an internal USB bus in the
NovaScale Blade Chassis. Some operating systems enable you to select
the type of mouse during installation of the operating system. Select USB.
If the problem remains, call for service.
