Removing DRAM SIMMS
Perform this procedure to remove DRAM SIMMs:
Step 1 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.
Step 2 On the mainboard, locate the DRAM SIMM sockets shown in Figure 5-5 or Figure 5-6.
Caution Handle SIMMs by the non-connector edges only. SIMMs are ESD-sensitive components and can be
damaged by mishandling.
Step 3 Remove one SIMM at a time, beginning with the SIMM in bank 3. To lift the SIMM out of its socket,
pull the locking spring clips on both sides outward and tilt the SIMM toward the right side of the chassis,
until it is free of the clips. (See Figure 5-8.)

Step 4 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.
Step 5 Repeat Step 3 and Step 4 for each SIMM.
2. Push the top of the
SIMM forward and down.
1. Pull the locking spring clips outward.
