You cannot connect to the Internet

Contact your ISP technical support for help.
Keyboard
Liquid has been spilled into the keyboard
• If you spilled liquid in the keyboard, turn off your server and unplug the keyboard. Clean
the keyboard and turn it upside down to drain it. Let the keyboard dry before using it again.
If the keyboard does not work after it dries, you may need to replace it. This type of damage
is not covered by your server’s warranty.
LED information
See “LED information” on page 8 for a description of this server’s LEDs and the information they
provide.
Memory
Memory errors were detected during server start up
• Open your server and make sure that the memory modules are installed correctly. For
instructions, see “Installing memory” on page 31.
• A memory module may be defective. If possible, try another memory module and see if
the error repeats.
Monitor
Your server is running but there is no picture
• Adjust the brightness and contrast controls to the center position.
• Make sure that the monitor is plugged in and turned on. If the monitor is turned on, the
power LED should be lit.
• Check the port and cable for bent or damaged pins.
• Connect your monitor to another computer, or connect a monitor that you know works
to your server.
The color is not uniform
Make sure that the monitor warms up for at least 30 minutes before making a final judgment
about color uniformity.
Make sure that:
• The monitor is not positioned too close to another monitor, electric fan, or fluorescent light.
• You demagnetize the screen using the monitor’s degauss feature. For more information
on degauss, see the monitor’s documentation.
