Prerequisites
Follow the safety guidelines listed in the Safety instructions.
Follow the procedure listed in the Before working inside your system
Power off the system and all attached peripherals.
Disconnect the system from the electrical outlet and disconnect the peripherals.
If applicable, remove the system from the rack.
Remove the system cover.
Remove the cooling shroud.
NOTE: The memory modules are hot to touch for some time after the system has been powered down. Allow the memory modules to cool before handling them. Handle the memory modules by the card edges and avoid touching the components or metallic contacts on the memory module.
CAUTION: To ensure proper system cooling, memory module blanks must be installed in any memory socket that is not occupied. Remove memory module blanks only if you intend to install memory modules in those sockets.
Removing memory modules:
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.
To release the memory module from the socket, simultaneously press the ejectors on both ends of the memory module socket.
Lift the memory module away from the system.
Installing memory modules:
Locate the appropriate memory module socket.
Open the ejectors on the memory module socket outward to allow the memory module to be inserted into the socket.
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.
Press the memory module with your thumbs until the socket levers 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.
Install the cooling shroud.
Install the system cover.
Place the system upright on its feet on a flat and stable surface.
Install the optional bezel.
If applicable, install the system into the rack. For more information, see the Rack installation placemat at Dell.com/poweredgemanuals.
Reconnect the system to an electrical outlet and peripherals.
Turn on the system and any attached peripherals.
Press F2 to enter System Setup, and check the System Memory setting.
The System Memory Size should reflect the installed memory.
If the value is incorrect, one or more of the memory modules may not be installed properly. Ensure that the memory modules are firmly seated in the sockets.
Run the system memory test in system diagnostics.
