Removing SDRAM DIMMS

Follow these steps to remove SDRAM DIMMs:

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.

Step 2 On the system board, locate the SDRAM DIMM sockets shown in Figure 7.

Caution Handle DIMMs by the edges only. DIMMs are ESD-sensitive components and can be damaged by

mishandling.

Step 3 Remove the DIMM by pushing the locking spring clips on both sides outward, as shown in step 2 of

Figure 9. This ejects the DIMM from its socket.
