Monitor and Terminal Problems

If the system starts up but has no startup display when you turn on the system, refer to
Table 8–11.
Table 8–11: Troubleshooting Monitor and Terminal Problems
Possible Cause
The monitor or terminal are not
turned on.
The monitor or terminal
brightness and contrast controls
are incorrectly set.
Incorrect graphics configuration.
The terminal cable is not
connected to the correct serial
port.
If you are using a console
terminal, check the baud rate
setting for the terminal and
system. The system default baud
rate setting is 9600.
The power cord is not connected.
The power cord may be faulty.
The power cord socket may not
be working.
If you are using other than the
standard on-board VGA
controller, settings may be
incorrect.
The terminal or monitor fuse may
have blown.

Action
Check that the monitor or terminal is turned on.
Make sure all cables are connected at both ends.
Adjust the monitor or terminal contrast and
brightness controls.
See Chapter 6, "Configuring Your System."
Check the serial port to which the terminal cable
is connected. Make sure it is connected to the
left-hand serial port (COM1).
Connect the console terminal to the COM1
serial communication port and set the console
environment variable to serial (set console
serial command).
Make sure all power cords are connected
correctly at both ends. Try a power cord that
works or test the power socket with an appliance
that works.
Make sure that on-board CIRRUS VGA options
are set to "disabled" through the ECU, the VGA
jumper (J27) on the upper-left corner of the
system board is disabled (off), and the
console environment variable is set to
"graphics."
Combining multiple VGA controllers will
produce unpredictable results, and use of
multiple VGA controllers is not recommended
or supported.
Replace the blown terminal or monitor fuse.
Refer to the terminal or monitor documentation.
