1. Revert the system to the minimum configuration. See “Specifications” on page 2 for the minimally
required number of processors and DIMMs.
2. Restart the system.
• If the system restarts, add each of the removed items one at a time and restart the system each time
until the error occurs. Replace the item for which the error occurs.
• If the system does not restart, suspect the system board.
Unusual smell
Complete the following steps until the problem is solved.
1. An unusual smell might be coming from newly installed equipment.
2. If the problem remains, contact Lenovo Support.
Server seems to be running hot
Complete the following steps until the problem is solved.
Multiple compute nodes or chassis:
1. Make sure that the room temperature is within the specified range (see “Environmental specifications”
on page 7).
2. Make sure that the fans are installed correctly.
3. Update the UEFI and XCC to the latest versions.
4. Make sure that the fillers in the server are installed correctly (see Maintenance Manual for detailed
installation procedures).
5. Use the IPMI command to ramp up the fan speed to the full fan speed to see whether the issue can be
resolved.
Note: The IPMI raw command should only be used by trained technician and each system has its own
specific PMI raw command.
6. Check the management processor event log for rising temperature events. If there are no events, the
compute node is running within normal operating temperatures. Note that you can expect some
variation in temperature.
