Voltage Planar Fault Is Displayed In The Event Log; Unusual Smell; Server Seems To Be Running Hot; Cannot Enter Legacy Mode After Installing A New Adapter - Lenovo ThinkSystem SD550 V3 User Manual

• The server restarts automatically and attempts POST again.
• The server hangs, and you must manually restart the server for the server to attempt POST again.
After a specified number of consecutive attempts (automatic or manual), the server reverts to the default
UEFI configuration and starts System Setup so that you can make the necessary corrections to the
configuration and restart the server. If the server is unable to successfully complete POST with the default
configuration, there might be a problem with the system board (system board assembly). You can specify the
number of consecutive restart attempts in System Setup. Click System Settings ➙ Recovery ➙ POST
Attempts ➙ POST Attempts Limit. Available options are 3, 6, 9, and 255.

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 the 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.
