Install a DIMM

Install a DIMM
1. Unpack the replacement DDR4 DIMM and place it on an antistatic mat.
2. Ensure that the replacement DDR4 DIMM matches the size of the DIMM it is
replacing.
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 Population Rules” on page 104 .
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.
