2. Attempt to log out of the system and log back in.
3. Validate the network access by pinging or running a trace route to the server from a command line.
a. If you are unable to get a response during a ping test, attempt to ping another server in the chassis
to determine whether it is a connection problem or server problem.
b. Run a trace route to determine where the connection breaks down. Attempt to resolve a
connection issue with either the VPN or the point at which the connection breaks down.
4. Restart the server remotely through the management interface.
5. If the problem remains, verify that any new software has been installed and configured correctly.
6. Contact your place of purchase of the software or your software provider.
Server is unresponsive (POST failed and cannot start System Setup)
Configuration changes, such as added devices or adapter firmware updates, and firmware or application
code problems can cause the server to fail POST (the power-on self-test).
If this occurs, the server responds in either of the following ways:
• 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 processor board or system I/O board. Do the following:
1. Remove any newly added devices and revert the system to the default hardware configuration.
2. Try to restart the system and check if it can boot to the System Setup successfully.
• If no, do the following:
a. Replace the processor board.
b. Replace the system I/O board.
• If yes, try to move the suspected device to another system under test (SUT).
– If the SUT system works normally, the issue maybe is caused by the processor board or system I/
O board.
– If the SUT system works abnormally, there might be a problem with the suspected device.
3. If all the suspected parts are isolated and the issue still remains unchanged, please run the affected
system to be minimum configuration for further detail issue isolation and add them back step by step.
Voltage planar fault is displayed in the event log
Complete the following steps until the problem is solved.
1. Revert the system to the minimum configuration. See
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 processor board first and then the system I/O board.
