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 B-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 B-9
. This ejects the DIMM from its socket.
