server.

CD/diskette/USB select button: Press this button to associate the CD-ROM drive,
diskette drive, and USB 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
CD-ROM drive, diskette drive, and USB port has been transferred to this blade
server. It can take up to 20 seconds for the operating system in this blade server to
recognize the CD-ROM drive, diskette drive, and USB port.
If there is no response when you press the CD/diskette/USB select button, you can
use the management-module Web interface to determine whether local control has
been disabled on the blade server.
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. It can
take up to 20 seconds to switch the keyboard, video, and mouse control to the
blade server.
