Possible Cause
The power-on password is

saver capabilities is being
used with energy saver
features enabled.
Either the cabling or the
monitor impedance is
incorrect.

is occurring.
Possible Solution

password, you must disable the
power-on password by using the
Password Disable switch on the system
board. Refer to your server-specific user
documentation for further information.

Be sure that the PCI Hot Plug slot has
power. Check the power LED on the
slot.
Be sure that the server and the
operating system support the expansion
board.
Disable the monitor energy saver
features.
