Troubleshooting charts

The following tables list problem symptoms and suggested solutions. See the blade server Hardware Maintenance Manual and Troubleshooting Guide on the Intel Server Compute Blade SBX82 Resource CD for more detailed troubleshooting charts. If you cannot find the problem in these charts, run the diagnostic programs.

Memory problems

physical memory installed.
	• If you changed the memory, you updated the memory configuration in the
	Configuration/Setup Utility program.
	• All banks of memory are enabled. The blade server might have
	automatically disabled a memory bank when it detected a problem, or a
	memory bank might have been manually disabled.

Check the POST error log for error message 289:

•If the DIMM was disabled by a system management interrupt (SMI), replace the DIMM.

•If the DIMMs are not installed in pairs, install DIMMs starting with DIMM 1 and DIMM 2. Make sure there is not an unpopulated DIMM slot in the middle and make sure DIMM 3 and DIMM 4 are installed before DIMM 1 and DIMM 2

•If the system halts, make sure the DIMMs are installed in dual-ranked pairs. Swap DIMM 3 and DIMM 4 with DIMM 1 and DIMM 2.

•If the system error indicates an unsupported memory configuration, make sure there is more than one DIMM installed. Install DIMMs in DIMM slots 1 and 2. If this does not correct the error, replace the DIMMs flagged in the management module log and indicated through the Light Path Diagnostics LEDs.

•If the DIMM was disabled by the user or by POST, run the Configuration/Setup Utility program and enable the DIMM.

•If this error remains, replace the DIMM.
