Chapter 3 Starting Up Server Diagnostics 25
If the Xserve EFI requires a password, you won’t be able to start up a NetBoot image
using the front panel. You need to disable the firmware password before you can use
the front panel. To disable the password, you must be able to start up Mac OS X Server
on the Xserve.
To use the Xserve front panel to start up a Server Diagnostics EFI NetBoot image:
1 Turn off the Xserve.
2 Hold down the system identifier button and press the on/standby button. Continue
holding down the system identifier button until the top row of lights blink in
sequence.

If the two rows of lights on the front panel blink once and the Xserve resumes its
startup sequence, a firmware password is enabled and you need to disable the
password.
For information about disabling the firmware password, see the next section,
“Disabling the Firmware Password.”
If both rows of lights blink once,
disable the firmware password.
