Keyboard/video select button: When you use an operating system that supports a
local console and keyboard, press this button to associate the shared BladeCenter
unit keyboard and video ports with the blade server.
Notes:
v The operating system in the blade server must provide USB support for the
blade server to recognize and use the keyboard, even if the keyboard has a
PS/2-style connector.
v The keyboard and video are available after partition firmware loads and is
running. Power-on self-test (POST) codes and diagnostics are not supported
using the keyboard and video. Use the management module to view
checkpoints.
The LED on this button flashes while the request is being processed, then is lit
when the ownership of the keyboard and video has been transferred to the blade
server. It can take approximately 20 seconds to switch control of the keyboard and
video to the blade server.
Using a keyboard that is directly attached to the management module, you can
press keys in the following sequence to switch keyboard 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. When you use some keyboards, such as the
28L3644 (37L0888) keyboard, hold down the Shift key while you enter this key
sequence.
If there is no response when you press the keyboard/video select button, you can
use the Web interface of the management module to determine whether local
control has been disabled on the blade server.
Media-tray select button: Press this button to associate the shared BladeCenter
unit media tray (removable-media drives and front-panel USB ports) with the
blade server. The LED on the button flashes while the request is being processed,
then is lit when the ownership of the media tray has been transferred to the blade
server. It can take approximately 20 seconds for the operating system in the blade
server to recognize the media tray.
If there is no response when you press the media-tray select button, use the
management module to determine whether local control has been disabled on the
blade server.
Note: The operating system in the blade server must provide USB support for the
blade server to recognize and use the removable-media drives and USB ports.
