Blade workstation controls and LEDs

This section describes the controls and LEDs on the blade workstation.
Note: The control panel door is shown in the closed (normal) position in the
KVM
select button
KVM select button: Press this button to associate the shared BladeCenter unit
keyboard, video, and mouse (KVM) with the blade workstation. 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
workstation. It can take approximately 20 seconds to switch the keyboard, video,
and mouse control from one blade workstation to another.
Using a keyboard that is directly attached to the management module, you can also
press keyboard keys in the following sequence to switch KVM control between
blade workstations:
Only USB keyboard, video, and mouse are supported. The operating system in the
blade workstation must provide USB support for the blade workstation 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 workstation integrated diagnostics
v Running a BIOS update diskette on a blade workstation
v Updating the diagnostics on a blade workstation
v Running the Broadcom firmware CD for a blade workstation
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 workstation.
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
workstation. The LED on the button flashes while the request is being processed,
and then is lit when the ownership of the media tray has been transferred to the
blade workstation. It can take approximately 20 seconds for the operating system in
the blade workstation to recognize the media tray.
