CD/diskette/USB select button: Press this button to associate the CD-ROM drive, diskette drive,
and USB port with this NovaScale Blade Server. The LED on this button flashes while the request is
being processed, then is lit when the ownership of the CD-ROM drive, diskette drive, and USB port
has been transferred to this NovaScale Blade Server. It can take approximately 20 seconds for the
operating system in this NovaScale Blade Server to recognize the CD-ROM drive, diskette drive,
and USB port.
The operating system in the NovaScale Blade Server must provide USB support for the NovaScale
Blade Server to recognize and use the CD-ROM drive, diskette drive, and USB port. The NovaScale
Blade Chassis unit uses the USB for internal communication with these devices. If there is no
response when you press the CD/diskette/USB select button, you can use the management-module
Web interface to determine whether local control has been disabled on the NovaScale Blade Server.
