Install a DIMM
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 119 .
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 socket 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.
4.
Repeat Step 3 until all replacement DIMMs are installed.
5.
Return the server to operation:
