Resolving installation issues

Make sure that the power button is working correctly:

1. Disconnect the server power cords.

2. Reconnect the power cords.

3. (Trained technician only) Reseat the operator information panel cable, and then repeat steps 1a and 1b.

   • (Trained technician only) If the server starts, reseat the operator information panel. If the problem remains, replace the operator information panel.

   • If the server does not start, bypass the power button by using the force power-on jumper. If the server starts, reseat the operator information panel. If the problem remains, replace the operator information panel.

Make sure that the reset button is working correctly:

1. Disconnect the server power cords.

2. Reconnect the power cords.

3. (Trained technician only) Reseat the operator information panel cable, and then repeat steps 2a and 2b.

   • (Trained technician only) If the server starts, replace the operator information panel.

   • If the server does not start, go to step 3.

Make sure that both power supplies installed in the server are of the same type. Mixing different power supplies in the server will cause a system error (the system-error LED on the front panel turns on).

• The power cords are correctly connected to the server and to a working electrical outlet.

• The type of memory that is installed is correct and the installation rules are met.

• The DIMMs are fully seated with lock latches fully closed.

• The LEDs on the power supply do not indicate a problem.

• The processors are installed in the correct sequence.

Reseat the following components:

1. Operator information panel connector

2. Power supplies

Replace the following components and restart the server each time:

1. Operator information panel connector

2. Power supplies

If you just installed an optional device, remove it, and restart the server. If the server now starts, you might have installed more devices than the power supply supports.

Implement the minimum configuration (one processor and one DIMM) to check whether any specific components lock the power permission.

Collect the failure information by capturing the system logs and provide it to Lenovo support.

See Power supply LEDs.

Correct any errors that are indicated by the light path diagnostics LEDs.

Make sure that the solution supports all the processors and that the processors match in speed and cache size.

You can view processor details from system setup.

To determine if the processor is supported for the solution, see Lenovo ServerProven website.

(Trained technician only) Make sure that processor 1 is seated correctly

(Trained technician only) Remove processor 2 and restart the solution.

Replace the following components one at a time, in the order shown, restarting the solution each time:

1. (Trained technician only) Processor

2. (Trained technician only) System board

Make sure that the optional embedded hypervisor flash device is selected on the boot manager <F12> Select Boot Device at startup.

See the documentation that comes with the optional embedded hypervisor flash device to validate that the device is configured correctly.

Make sure that other software works on the server.

Verify that the drive is supported for the server. See Lenovo ServerProven website for a list of supported hard drives.

Make sure that the drive is seated in the drive bay properly and that there is no physical damage to the drive connectors.

Run the diagnostics tests for the SAS/SATA adapter and hard disk drives. When you start a solution and press the key according to the on-screen instructions, the LXPM interface is displayed by default. (For more information, see the “Startup” section in the LXPM documentation compatible with your solution at Lenovo XClarity Provisioning Manager portal page.) You can perform hard drive diagnostics from this interface. From the Diagnostic page, click Run Diagnostic > HDD test/Disk Drive Test.

Depending on the LXPM version, you may see HDD test or Disk Drive Test.

• No error LEDs are lit on the operator information panel.

• No DIMM error LEDs are lit on the system board.

• Memory mirrored channel does not account for the discrepancy.

• The memory modules are seated correctly and followed the system memory installation rules.

• You have installed the correct type of memory.

• If you changed the memory, you updated the memory configuration in the Setup utility.

• Check that all banks of memory are enabled in the UEFI setup. The server might have automatically disabled a memory bank when it detected a problem, or a memory bank might have been manually disabled by a previous user.

• There is no memory mismatch when the server is at the minimum memory configuration.

Reseat the DIMMs, and then restart the server.

Check the POST error log:

• If a DIMM was disabled by a systems-management interrupt (SMI), move the DIMM to a different slot and run the UEFI setup utility to confirm if the DIMM is enabled, if the DIMM is still disabled then replace the DIMM.

• If a DIMM was disabled by the user or by POST, move the DIMM to a different slot and run the UEFI setup utility to confirm if the DIMM is enabled, if the DIMM is still disabled then replace the DIMM.

Reverse the DIMMs between the channels (of the same processor), and then restart the server. If the problem is related to a DIMM, replace the failing DIMM.

Re-enable all DIMMs using the Setup utility, and then restart the server.

(Trained technician only) Install the failing DIMM into a DIMM connector for processor 2 (if installed) to verify that the problem is not the processor or the DIMM connector.

(Trained technician only) Replace the system board.

Revert the system to the minimum configuration. See Specifications for the minimally required number of processors and DIMMs.

Restart the system.

• If the system restarts, add each of the items that you removed one at a time, restarting the system each time, until the error occurs. Replace the item for which the error occurs.

• If the system does not restart, replace the system board.
