Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin.
Connect the equipment end of the wrist strap to the metal back plate of the chassis, avoiding
contact with the connectors.
On the motherboard, locate the main memory SIMM card sockets shown in the upper right
of Figure 8.
Handle SIMMs by the card edges only. SIMMs are ESD-sensitive components and can be
Remove one SIMM at a time, beginning with the SIMM farthest from the edge of the
motherboard.
To lift the SIMM out of its socket, pull the locking spring clips on both sides outward and
tilt the SIMM free of the clips. (See Figure 11.)
Hold the SIMM by the edges with your thumb and index finger and lift it out of the socket.
Place the removed SIMM in an antistatic bag to protect it from ESD damage.
Repeat Step 2 through Step 5 for each main memory SIMM card.
Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin.
Connect the equipment end of the wrist strap to the metal back plate of the chassis, avoiding
contact with the connectors.
On the motherboard, locate the main memory SIMM card sockets shown in the upper right
of Figure 8. All the sockets should be empty. If they are not, follow the steps in the previous
section "Removing Main Memory SIMMs."
Handle SIMMs by the card edges only. SIMMs are ESD-sensitive components and can be
Hold the SIMM with the polarization notch on the right and the component side away from
you with the connector edge at the bottom. (See Figure 10.)
Beginning with the SIMM nearest the edge of the motherboard, insert the main memory
SIMM card at a 45-degree angle and rock it into its vertical position (see Figure 12), using
the minimum amount of force required. When the SIMM is properly seated, the socket
guide posts will insert through the alignment holes, and the locking springs will click into
place.
Ensure that each SIMM is straight and that the alignment holes (as shown in Figure 10) line
up with the plastic socket guides.
