Figure 10. Removing a DIMM module
11. Remove the defective DIMM module.
12. Insert a new DIMM module into the socket from which you removed the failed DIMM module.
Verify that the small tab on the DIMM module aligns with the tab on the socket.
Note: The DIMM sockets on the motherboard are labeled 1A, 1B; 2A, 2B; 3A, 3B; and 4A, 4B. For
nodes with 4 GB of RAM, DIMM modules occupy all of the A slots with the B slots left empty.
13. Gently press down on both ends of the DIMM module until the two socket arms lock into place, securing the DIMM
module.
14. Install the air baffle.
For more information, see
Installing the air baffle
on page 40.
15. Replace the node top panel.
For more information, see
Installing the node top panel
on page 35.
16. Connect both power cables to the node power supplies and verify that the node starts properly and displays the log
in prompt.
Note: If a new DIMM is not properly installed or is corrupt, the node will beep during the startup process.
17. Log in to the node, and then run the following command:
sysct1 -n hw.physmem
If the node returns the correct value for the amount of RAM installed to the node (about 4,250,000,000 bytes for a
4 GB node), the DIMM is functioning correctly.
18. Return the old hardware to Isilon Technical Support.
