Keyboard/video/mouse (KVM) select button: Press this button to associate the
shared BladeCenter unit keyboard port, video port, and mouse port with the blade
server. The LED on this button flashes while the request is being processed and
then is lit when the ownership of the keyboard, video, and mouse has been
transferred to the blade server. It can take approximately 20 seconds to switch the
keyboard, video, and mouse control to the blade server.
Using a keyboard that is directly attached to the management-module, you can
press keyboard keys in the following sequence to switch KVM control between
blade servers instead of using the KVM select button:
NumLock NumLock blade_server_number Enter
blade_server_number is the two-digit number of the blade-server bay in which
the blade server is installed. A blade server that occupies more than one
blade-server bay is identified by the lowest bay number that it occupies.
If there is no response when you press the KVM select button, you can use the
management-module Web interface to determine whether local control has been
disabled on the blade server. See http://www-03.ibm.com/systems/management/
for more information.
Notes:
1.
The operating system in the blade server must provide USB support for the
blade server to recognize and use the keyboard and mouse, even if the
keyboard and mouse have PS/2-style connectors.
2. If you install a supported Microsoft
®
Windows
®
operating system on the blade
server while it is not the current owner of the keyboard, video, and mouse, a
delay of up to 1 minute occurs the first time that you switch the keyboard,
video, and mouse to the blade server. All subsequent switching takes place in
the normal KVM switching time frame (up to 20 seconds).
