model the boot priority sequence is:
●
USB device
●
PXE
1. When the unit boots, the monitor should display the following information:

Item Information Action
MAC Address NIC portion of the system board is OK If no MAC Address, the system board is at fault. Contact the
Call Center for service.
GUID General system board information If no GUID information, the system board is at fault and
should be replaced.
Client ID Information from server If no Client ID information there is no network connection. This
may be caused by a bad cable, the server is down, or a bad
system board. Contact the Call Center for service for the bad
system board.
MASK Information from server If no MASK information there is no network connection. This
may be caused by a bad cable, the server is down, or a bad

may be caused by a bad cable, the server is down, or a bad

If you are running in a Microsoft RIS PXE environment, go to step 2.
If you are running in a Linux environment, go to step 3.
2. If you are running in a Microsoft RIS PXE environment, press the F12 key to activate the network service
boot as soon as the DHCP IP information appears on the screen.
If the unit does not boot to the network, the server is not congured to PXE.
If you missed the F12 cue, the system will try to boot to the ATA ash that is not present. The message on
the screen will read: ERROR: Non-system disk or disk error. Replace and press any key when ready.
Pressing any key will restart the boot cycle.
3. If you are running in a Linux environment, an error message will appear on the screen if there is no Client IP.
ERROR: Non-system disk or disk error. Replace and press any key when ready.
