Removing and Installing SDRAM DIMMs on the Cisco 2691
Step 4
Hold the DIMM by the edges with your thumb and index finger and lift it out of the socket, as shown in
step 1 of
Figure B-9
. Place the removed DIMM in an antistatic bag to protect it from ESD damage.
Step 5
If necessary, repeat
Step 3
and
Step 4
for the other DIMM.
Installing SDRAM DIMMs
Follow this procedure to install 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 nonconnector edges only. DIMMs are ESD-sensitive components and can be
damaged by mishandling.
Step 3
Hold the DIMM with the polarization notch on the right, near the rear of the chassis, and with the
connector edge at the bottom.
