CAUTION: To prevent damage to the memory module or the memory module socket during installation, do
not bend or flex the memory module; insert both ends of the memory module simultaneously.
2. If a memory module or a memory module blank is installed in the socket, remove it.
3. Align the edge connector of the memory module with the alignment key of the memory module socket, and insert the
memory module in the socket.
NOTE: The memory module socket has an alignment key that enables you to install the memory module in the socket in
only one orientation.
CAUTION: Do not apply pressure at the center of the memory module; apply pressure at both ends of the
memory module evenly.
4. Press the memory module with your thumbs until the ejectors firmly click into place.
When the memory module is properly seated in the socket, the levers on the memory module socket align with the levers on
the other sockets that have memory modules installed.

Expansion cards and expansion card risers
NOTE:
A System Event Log (SEL) event is logged if an expansion card riser is not supported or missing. It does not prevent
your system from turning on. However, if a F1/F2 pause occurs with an error message, see Troubleshooting expansion
cards section in the Dell EMC PowerEdge Servers Troubleshooting Guide at www.dell.com/poweredgemanuals.
