138 Installing System Components
After removing the processor, place it in an antistatic container for reuse, 
return, or temporary storage. Do not touch the bottom of the processor. 
Touch only the side edges of the processor. 
If you are permanently removing the processors from processor sockets 3 
and 4, you must install a FlexMem Bridge and a heat-sink blank in the 
empty socket to ensure proper system cooling. See "Installing a FlexMem 
Bridge" on page 141. If you are removing the processor from processor 
socket 2, you must install a heat-sink blank in the empty socket.
