Install a DIMM
You must not replace a single-rank or dual-rank DIMM with a quad-rank DIMM and vice versa.
If you violate this rule, the performance of the server might be adversely affected. For DIMM
socket population rules, see “DIMM Layout and Population Rules” on page 75.
3.
Install a DIMM.
a.
Ensure that the ejector tabs are in the open position.
b.
Align the notch in the replacement DIMM with the connector key in the
connector socket.
The notch ensures that the DIMM is oriented correctly.
c.
Push the DDR4 DIMM into the connector until the ejector tabs lock the DIMM
in place.
If the DIMM does not easily seat into the connector socket, verify that the notch in the
DIMM is aligned with the connector key in the connector socket. If the notch is not
aligned, damage to the DIMM might occur.
Note - If you want to move a faulty DDR4 DIMM to a new DIMM socket or reseat a DIMM
for troubleshooting, you must first manually clear the associated DIMM fault. Otherwise, the
DIMM fault might follow the DIMM to the new socket location or reoccur on the current socket
location, possibly causing a false DIMM fault condition.
4.
Replace the air baffle.
5.
Return the server to operation.
See “Returning the Server to Operation” on page 145.
6.
(Optional) Use Oracle ILOM to clear DDR4 DIMM faults.
DDR4 DIMM faults are automatically cleared after a new DIMM has been installed. If you
need to manually clear DDR4 DIMM faults, refer to the Oracle Integrated Lights Out Manager
(ILOM) 3.2 Documentation Library at http://www.oracle.com/goto/ILOM/docs.
