Chapter 11 206
Added a Second Processor
If you have added a second processor and the system won't boot:
1. Turn off the display and shut down the Workstation. Disconnect all
power cables and any LAN or telecommunications cables.
2. Remove the Workstation’s cover.
3. Set system board switch 4 to
ON
(see “System Board Switches” on
page 28).
4. If the system boots, enter the setup program by pressing
F2
and go to
the advanced menu (see “Advanced Menu” on page 52) to check the
processor speed setting. If it is set to
Auto
, your processors may have
different frequencies. This is not supported.
Keyboard Doesn’t Work
If your keyboard does not work as expected:
• Ensure that all the keyboard cables are firmly connected.
• Ensure the keyboard is connected to the keyboard connector rather
than the mouse connector on the rear panel of the Workstation.
• Ensure you are using a PS2 keyboard rather than a USB keyboard.
• Replace the keyboard with a known working unit to ensure the
keyboard itself is not defective.
Monitor Doesn’t Work
If the display is blank, refer to “Display is Blank” on page 205.
If the display works properly during the Power-on-Self-Test (POST), but
goes blank when Windows starts, the display settings in the operating
system may not be compatible with your monitor. To correct this, restart
your Workstation in VGA mode:
• Windows NT: Enter VGA mode when prompted during start-up.
• Windows 2000: When prompted, press
F8
and start the Workstation
in VGA mode.
After the Workstation is up and running, change the display settings in
the control panel (
Start > Settings > Control Panel
). Refer to your operating
system documentation for more information.
