3. Power down the system, remove drive mounting panel(s) from the
system, and remove the graphics module from the system module. If
the graphics module was not installed, then proceed to step 5. When
you power-up the system after removing the graphics module, you
must either connect an alternate console terminal to the printer port
and set
S3
to the up position (9600 baud rate) or watch the LEDs to
see if the system does or does not power up successfully. The alternate
console is used to display the video because there is no video signal
output to the monitor when the graphics module is disconnected.
4. Power-up the system with the graphics module disconnected. If the
system still does not power up properly, the problem is not in the
graphics module, then proceed to step 5. If the system does power up
successfully, replace the graphics module and retest the system.
5. Power down the system, remove the memory module from the system
module.
6. Power up the system with the memory module disconnected. If
the system does not power up properly, the problem is not the
memory module, then proceed to step 7. If the system does power
up successfully, replace the memory module and retest the system.
7. Power down the system. Replace the system module and power up
the system again. If the system still does not power up properly after
replacing the system module, replace the power cable.
