5Remove the sled from the enclosure. See "Removing a Compute Sled" on page 192. See the compute sled’s documentation for more information.

6Check the memory channels and ensure that they are populated correctly.

7Reseat the memory modules in their sockets. See the compute sled’s documentation for more information.

8Reinstall the sled into the enclosure.

9Turn on the sled and attached peripherals.

10Enter the System Setup program and check the system memory settings. See "Main Menu" on page 74.

If the problem is not resolved, proceed with the next step.

11Turn off the sled and attached peripherals.

12Remove the sled from the enclosure.

13If a diagnostic test or error message indicates a specific memory module as faulty, swap or replace the module.

14To troubleshoot an unspecified faulty memory module, replace the memory module in the first DIMM socket with a module of the same type and capacity. See the compute sled’s documentation for more information.

15Reinstall the sled into the enclosure.

16Turn on the sled and attached peripherals.

17As the system boots, observe any error message that appears and the diagnostic indicators on the front of the system.

18If the memory problem is still indicated, repeat step 11 through step 17 for each memory module installed.

19If the problem persists after all memory modules have been checked, see "Getting Help" on page 289.
