WARNING: Allow the memory modules to cool after you power off the sled. Handle the memory modules by the card edges and
avoid touching the components or metallic contacts on the memory module.
CAUTION: To ensure proper sled 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 the
Thermal restrictions section.
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.
2 Push the ejectors outward on both ends of the memory module socket to release the memory module from the socket.
3 Lift and remove the memory module from the sled or PEM.

2 If you are removing the memory module permanently, install a memory module blank. The procedure to install a memory module blank
is similar to that of the memory module.
NOTE: For the minimum sled configuration, two processors are required on the system board. Install the processor/DIMM blank
on the processor 3/4 sockets on the PEM board.
