Keyboard/mouse/video select button: Press this button to associate the keyboard
port, mouse port, and video port with this blade server. The LED on this button
flashes while the request is being processed, then is steady when the ownership of
the keyboard, mouse, and video has been transferred to this blade server.
Notes:
1. The operating system in the blade server must provide USB support for the
blade server to recognize and use the keyboard, mouse, CD-ROM drive, and
diskette drive. The BladeCenter unit uses USB for internal communication with
these devices.
2. It can take approximately 20 seconds to switch the keyboard, video, and mouse
or the CD-ROM drive, diskette drive, and USB port to the blade server.
3. If you install Microsoft Windows 2000 on the blade server while it is not the
current owner of the keyboard, video, and mouse, a delay of up to one minute
occurs the first time you switch the keyboard, video, and mouse to the blade
server. During this one-time-only delay, the blade server Device Manager
enumerates the keyboard, video, and mouse and loads the device drivers. All
subsequent switching takes place in the normal keyboard-video-mouse
switching time frame.
4. The blade-error LED, information LED, and location LED can be turned off
through the BladeCenter management-module Web interface or the IBM
Director console. The IBM Director program is a system-management product
that comes with the BladeCenter unit.
Power-control button: This button is located behind the control panel door. Press
