Removing a memory module
Prerequisites
1. Follow the safety guidelines listed in
on page 16.
2. Follow the procedure listed in
Before working inside your sled
on page 17.

WARNING:
Allow the memory modules to cool after you power off the system. 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.
NOTE:
You must follow the thermal restriction while using DIMM blank. For information about thermal restriction, see
Thermal restrictions in Technical specification guide.
Steps
1. Locate the appropriate memory module socket.
WARNING:
Handle each memory module only by the card edges, ensuring not to touch the middle of the
memory module or metallic contacts.
2. Push the ejectors outward on both ends of the memory module socket to release the memory module from the socket.
3. Lift the memory module from the system.
