Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the
Step 1
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
Caution Handle SIMMs by the edges only. SIMMs are ESD-sensitive components and can be damaged by
mishandling.
Hold the SIMM with the polarization notch on the right, near the front of the chassis, and with the
Step 3
