| Power supply - squealing, scratching, or grinding noise. | - If the server is running redundant power, pull and replace each power supply, one at a time, to determine which power supply is causing the noise.
- If a single power supply is identified as causing the problem, complete the following steps:
- Make sure that the power supply causing the noise does not have an obstruction (cable, cable label, etc).
- Replace the power supply.
- If the noise can not be associated with a single power supply, it might be coming from the cooling fans.

| Power supply - Jet or fast-moving air noise. | Check the IMM event log for events associated with thermals, cooling, and fans. |
| Power supply - Clicking or rattling noise. | - If the server is running redundant power, pull and replace each power supply, one at a time, to determine which power supply is causing the noise.
- If a single power supply is identified as causing the problem, complete the following steps:

| Fans - Squealing, scratching, or grinding noise. | - This server has redundant hot-swap cooling. Remove and replace each fan assembly, one at a time, to determine which assembly is causing the noise.
- If a single fan assembly is identified as causing the problem, complete the following steps:
- Make sure that the fan assembly causing the noise does not have an obstruction (cable, cable label, etc) touching the fan blades during operation.
- Replace the fan assembly.
- If the noise can not be associated with a single fan assembly, it might be coming from the cooling fans in a power supply.

| Visible physical damage; Broken, damaged, or malfunctioning door, bezel, cover, or chassis part. | If the part is a CRU, replace it. If the part is a FRU, the part must be replaced by a trained service technician (see Parts listing, System x3850 X6 and x3950 X6 Type 6241 to determine whether the part is a FRU or a CRU and Removing and replacing components.) |
| Server is unresponsive (POST is complete and operating system is running) | If you are in the same location as the server, complete the following steps: - If you are using a KVM connection, make sure that the connection is operating correctly. Otherwise, make sure that the keyboard and mouse are operating correctly.
- If possible, log in to the server and verify that all applications are running (no applications are hung).
- Restart the server.
- If the problem remains, make sure that any new software has been installed and configured correctly.
- Contact your place of purchase of the software or your software provider.
If you are accessing the server from a remote location, complete the following steps: - Make sure that all applications are running (no applications are hung).
- Attempt to log out of the system and log back in.
- Validate the network access by pinging or running a trace route to the server from a command line.
- 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.
- 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.
- Restart the server remotely through the management interface.
- If the problem remains, verify that any new software has been installed and configured correctly.
- Contact your place of purchase of the software or your software provider.
