General problem determination procedures
Use the information in this section to resolve problems if the event log does not contain specific errors or the server is inoperative.
Turn off the server.
Ensure that the server is cabled correctly.
- Remove or disconnect the following devices, one at a time, until you find the failure. Turn on and configure the server each time you remove or disconnect a device.
NoteFor minimal configuration for debugging, see
Any external devices
Surge-suppressor device (on the server)
Printer, mouse, and non-Lenovo devices
DIMMs until you reach the minimum configuration that is supported for the server
Turn on the server.
If the problem is solved when you remove an adapter from the server, but the problem recurs when you install the same adapter again, suspect the adapter. If the problem recurs when you replace the adapter with a different one, try a different PCIe slot.
If the problem appears to be a networking problem and the server passes all system tests, suspect a network cabling problem that is external to the server.
