Possible cause
System problems (continued)
One of the following:
• Missing or faulty DIMMs,
or faulty DIMM connections
• Faulty HDD
• Overheated or faulty CPU(s)
• Faulty motherboard
Suggested action
1. 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
100).
Make sure that an even number of DIMMs is installed.
Odd-numbered configurations are not supported.
2. If the problem persists, test the DIMMs by removing
all DIMMs except for the one installed in J11, and
reboot the system.
If the system boots to Idle, install a different DIMM in
J11 and reboot the system. Continue to install a
different DIMM in the socket and reboot the system
until the system fails to reach Idle. The last DIMM that
you installed may be faulty and should be replaced.
N
:
If the system fails to reach Idle with each DIMM
OTE
installed in J11, the DIMM socket may be faulty and you
may need to replace the motherboard.
3. If the problem persists, check for a faulty HDD.
N
:
To troubleshoot the HDDs, connect a monitor,
OTE
keyboard, and mouse to the imagePRESS Server.
Reboot the system. At the Serial ATA AHCI BIOS
screen on the monitor, wait for the Port-XX displays to
appear and press the Pause/Break key. If a HDD
description appears next to the Port-01, Port-02, and
Port-03 entries, all three HDDs are good.
If "No device detected" appears next to:
– Port-01, the 250GB HDD in the top slot of the chassis
may be faulty.
– Port-02, the 500GB HDD in the middle slot may be
faulty.
– Port-03, the 500GB HDD in the bottom slot may be
faulty.
Replace the SATA data cable to the suspected faulty
drive. If the problem persists, replace the faulty drive.
