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.
Check in Setup Utility and make sure all the installed components are enabled.
Make sure the firmware of the installed components are the latest version.
Turn off the server.
Ensure that the server is cabled correctly.
- Remove or disconnect the following devices if applicable, one at a time, until you find the failure. Turn on and configure the server each time you remove or disconnect a device.
NoteThe minimum configuration required for the server is as the following:
Any external devices
Surge-suppressor device (on the server)
Printer, mouse, and non-Lenovo devices
One memory module at a time until you reach the minimum configuration that is supported for the server
- One processor
- One 8 GB ECC UDIMM in slot 1
- One power supply
- One 3.5-inch drive in drive bay 1
- Power cord
- One system front fan
Turn on the server.
Listen to the POST error beeps.
Table 1. POST error beeps Beep Error description Three short ones followed by one long one No memory is detected by the system. Two long one followed by three short ones No video card (including intergrated video card) is detected by the system.NoteA short beep lasts about 0.4 second, while a long one lasts about 0.9 second.
If the problem is solved after an adapter is removed from the server, but recurs after it is reinstalled, suspect the adapter. If the problem recurs when the adapter is replaced with a different one, try the original adapter in a different PCIe slot.
If the problem appears to be a networking one while the server passes all system diagnostics, suspect a network cabling problem that is external to the server.
