Power-control button
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 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.
You can also press keyboard keys in the following sequence to switch keyboard,
mouse, and video control between blade servers:
NumLock NumLock
blade_server_number
Enter
Where
blade_server_number
is the two-digit number for the blade bay in which
the blade server is installed.
Although the keyboard that is attached to the BladeCenter unit is a PS/2-style
keyboard, internal communication with it is through the USB. The operating system
in the blade server must provide USB support for the blade server to recognize and
use the keyboard and mouse. When you are not running an operating system that
has USB device drivers, such as in the following situations, the keyboard responds
very slowly:
v
Running the blade server integrated diagnostics
v
Running a BIOS update diskette on a blade server
v
Updating the diagnostics on a blade server
v
Running the Broadcom firmware CD for a blade server
If there is no response when you press the keyboard/video/mouse select button,
you can use the management-module Web interface to determine whether local
control has been disabled on the blade server.
