Suggested action
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.
Suggested action
v Make sure that the keyboard/mouse/video select button LED on the front of the
blade server is lit, indicating that the blade server is connected to the shared
BladeCenter mouse.
v Make sure that the mouse cable is securely connected to the BladeCenter
management module and that the keyboard and mouse cables are not reversed.
v Make sure that the mouse works correctly with other blade servers.
v Make sure that the mouse is recognized as a USB device, not PS/2, by your blade
server. Although the mouse is a PS/2-style device, communication with the mouse
is through an internal USB bus in the BladeCenter unit. Some operating systems
allow you to select the type of mouse during installation of the operating system.
Select USB.
If the problem remains, call for service.
