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.
