USB is disabled and no USB device will work during POST.
– The correct USB device driver is installed.
– The operating system supports USB devices.

it directly to the server.

DVD-ROM drive, diskette drive, keyboard, USB ports (except for Remote
Supervisor Adapter II-EXA functionality), mouse, and video are disabled on

ServerGuide problems
FRU/action
v Ensure that the system is a supported server with a startable (bootable)
CD-ROM drive.
v If the startup (boot) sequence settings have been altered, ensure that the
CD-ROM drive is first in the startup sequence.
v If more than one CD-ROM drive is installed, ensure that only one drive is set as
the primary drive. Start the CD from the primary drive.
v Ensure that there are no duplicate SCSI IDs or IRQ assignments.
v Ensure that the hard disk drive is connected properly.
Make more space available on the hard disk.
Ensure that the NOS CD you have is supported by the ServerGuide program.
See the CD label for a list of supported NOS versions.
Ensure that the NOS is supported on the server. If the NOS is supported, either
there is no logical drive defined (ServeRAID systems). Run the ServerGuide setup
and configuration program, and ensure that setup is complete.
