General problem determination procedures
Use the information in this section to resolve problems if the event log does not contain specific errors or the solution is inoperative.
Power off the solution.
Make sure that the solution is cabled correctly.
- Remove or disconnect the following devices if applicable, one at a time, until you find the failure. Power on and configure the solution each time you remove or disconnect a device.
NoteThe minimum configuration required for the node to start is one processor and one 2 GB DIMM.
Any external devices.
Surge-suppressor device (on the solution).
Printer, mouse, and non-Lenovo devices.
Hard disk drives.
Memory modules until you reach the minimum configuration that is supported for the solution.
See Specifications to determine the minimum configuration for your server.
Power on the solution.
If the problem is solved when you remove an adapter from the solution, 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 solution passes all system tests, suspect a network cabling problem that is external to the server.
