Monitor
Run the Setup Utility and make sure the monitor type shown matches the
monitor installed. (See Appendix, “Model/Monitor Configurations and FRU
Part Numbers” on page A-1.) First, set the system to VGA mode by holding
down both mouse buttons and turning on the machine. Then, reset the
monitor type in the Setup Utility.
If you need to set an option in the Setup Utility:
1. Make sure the Advanced Diagnostics diskette is in Drive A.
2. Power on the system unit.
3. Press F1 while the memory count is running.
You may be testing a digital monitor with a row of LEDs under the control
access door at the front of the monitor. If the monitor type is set to the
wrong mode in the Setup Utility, the screen remains black and the first and
last LEDs flash.
Note: Some monitors have a detachable system I/O signal cable between
the monitor and the system unit. Check the line voltage, power cord,
and continuity for the system I/O signal cable before replacing the
unit. See “Detachable Monitor I/O Signal Cable Connector Test
Points” on page 5-21 for pin identification.
High voltage Northern and Southern Hemisphere monitors may come
with a voltage selector (110 V–220 V) switch. The 145-W power
supply may have a voltage selector (110 V–220 V) switch. Match
the switch to the line voltage.
Ensure the correct monitor frequency is set in the Setup Utility for the
monitor used with the system (see “Using the Setup Utility” on page 1-16).
If the monitor frequency is set incorrectly, the monitor may not be readable
in certain modes. To determine the correct monitor frequency, look on the
monitor for the part number. If the part number is not listed, see the product
information shipped with the monitor. Set the monitor frequency equal to or
less than the monitor’s maximum horizontal frequency (also known as the
horizontal scan rate). See “Refresh Rates and Monitor Frequencies” on
page 1-12.
001
– Power off the system unit and monitor.

system unit and monitor.
