Installing A Memory Module - Dell EMC PowerEdge R740 Installation And Service Manual

Installing a memory module

The procedure for installing a DIMM module and an NVDIMM-N module is identical.
Prerequisites
Follow the safety guidelines listed in
CAUTION: Ensure that you install the NVDIMM-N battery if you are using NVDIMM-N.
CAUTION: To prevent data loss and potential damage to your system, ensure that your system, LEDs on system, LEDs on
NVDIMM-N and LEDs on NVDIMM-N battery are turned off before installing the NVDIMM-N battery.
Steps
1 Locate the appropriate memory module socket.
CAUTION: Handle each memory module only by the card edges, ensuring not to touch the middle of the memory module or
metallic contacts.
CAUTION: To prevent damage to the memory module or the memory module socket during installation, do not bend or flex
the memory module. You must insert both ends of the memory module simultaneously.
2 Open the ejectors on the memory module socket outward to allow the memory module to be inserted into the socket.
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.
CAUTION: Do not apply pressure at the center of the memory module; apply pressure at both ends of the memory module
evenly.
NOTE: The memory module socket has an alignment key that enables you to install the memory module in the socket in only
one orientation.
4 Press the memory module with your thumbs until the socket levers firmly click into place.

memory.
4 If the value is incorrect, one or more of the memory modules may not be installed properly. Ensure that the memory module is firmly
seated in the memory module socket.
5 Run the system memory test in system diagnostics.
