Step 6
When both ends of the SIMM are released from the socket, grasp the ends of the SIMM
with your thumb and forefinger and pull the SIMM completely out of the socket. Handle
the edges of the SIMM only; avoid touching the memory module or pins, and the metal
traces, or fingers, along the socket edge.
Step 7 Place the SIMM in an antistatic bag to protect it from ESD damage. You can use the
SIMMs that you remove in compatible equipment.
Step 8 Repeat Step 4 through Step 7 for the remaining SIMMs.
This completes the SIMM removal procedure. Proceed to the following section “Installing New
Memory SIMMs.”
