Installation and Service Guide: Color Controller E-85
Suggested action
1 Power off, wait 10 seconds, and then power on again.
2 If problem persists, check all cables and connections
again and reboot.
Make sure that the keyboard and mouse are installed in
the proper connectors. Power off, wait 10 seconds, and
power on again.
3 Check the DIMMs and reseat them to remove any
oxidation on the connectors (see
that the DIMM configurations in both socket sets are
identical (see page 66).
4 If the problem persists, test the DIMMs by removing
all DIMMs except for the ones installed in A0 and E0
and reboot the system.
If the system boots to Idle, install a different DIMM in
the available slot indicated in
DIMM slots" on page 67 and reboot the system.
Continue to install a different DIMM in the slot and
reboot the system until the system fails to reach Idle.
The last DIMM that you installed may be faulty and
should be replaced.
Note: If the system fails to reach Idle with each DIMM
installed in the next available slot, the DIMM socket may
be faulty and you may need to replace the motherboard.
5 If the problem persists, verify CPU and CPU fan
connections, and verify that the CPU heatsinks are
securely installed (see
Test the CPUs by removing the CPU installed in socket
CPU1 and rebooting.
•
If the system fails to boot up properly, the CPU in
socket CPU0 is faulty and should be replaced.
•
If the system boots up properly, the CPU in socket
CPU0 is good and the CPU that you removed from
socket CPU1 may be faulty. To test this, remove the
CPU from socket CPU0, install the other CPU in
socket CPU0, and reboot. If the system fails to boot
up properly, the CPU currently installed in socket
CPU0 is faulty and should be replaced.
6 If the problem persists, you may need to replace the
motherboard (see page
Troubleshooting
page 66). Make sure
