SOLVING PROBLEMS
When the server fails to operate as expected, see the following to find out your problem and follow the provided
instructions before asking for repair.
If the server still fails to operate successfully, note the on-screen messages and contact your service representative.
Problems with the Server
No screen display appears with beep:
Are the DIMMs installed securely?
→ Check whether the DIMMs are connected firmly to their mating connectors.
→ Check whether DIMMs of different specifications are installed in the specific group. See Chapter 9 for
the correct DIMMs specifications.
Fail to power on the server:
Is the server properly supplied with power?
→ Check if the power cord is connected to a power outlet (or UPS) that meets the power specifications
for the server.
→ Make sure to use the power cord provided with the server.
→ Check the power cord for a broken shield or bent plugs.
→ Make sure that the power breaker for the connected power outlet is on.
→ If the power cord is plugged to a UPS, make sure the UPS is powered on and that it outputs power.
See the manual that comes with the UPS for details.
Power supply to the server must be linked with the connected UPS using the BIOS setup utility of the
server.

Did you press the POWER/SLEEP switch?
→ Press the POWER/SLEEP switch on the front of the server to power on (the POWER/SLEEP LED
lights).
POST fails to complete:
Is the DIMM board installed?
→ At least two DIMM boards are required for operation.
Is the memory size large?
→ The memory check may take a few minutes if the memory size is large. Wait for a while.
Did you perform any keyboard or mouse operation immediately after you started the server?
→ If you perform any keyboard or mouse operation immediately after start-up, the POST may
accidentally detect a keyboard controller error and stop proceeding. In such a case, restart the server.
Do not perform any keyboard or mouse operation until the BIOS start-up message appears when you
restart the server.
Does the server contains appropriate memory boards or PCI devices?
→ Operation of the server with unauthorized devices is not guaranteed.
