Install a DIMM
96 Oracle Server X6-2 Service Manual • June 2016
You must not replace a 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 Population Rules” on page 88 .
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 re-seat 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. Repeat Step 3 until all replacement DDR4 DIMMs are installed.
5. Return the server to operation.
a. Install the server top cover.
See “Install the Server Top Cover” on page 188 .
b. Close the fan door.
c. Return the server to the normal rack position.
See “Return the Server to the Normal Rack Position” on page 191 .
d. Reconnect the power cords to the server power supplies and reconnect the
data cables.
See “Reconnect Data Cables and Power Cords” on page 193 .
e. Power on the server.
See “Power On the Server” on page 194 .
Verify that the Power/OK status indicator is steady on.
