Chapter 5 Installing Memory in the Router

Replacing DRAM and SDRAM

Installing DRAM SIMMs

Perform this procedure to install 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 5-5or Figure 5-6.

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

Step 3 Hold the SIMM with the polarization notch on the right, near the front of the chassis, and with the connector edge at the bottom.

Step 4 Beginning with bank 0, insert the SIMM into the socket at an angle, tilted toward the right side of the chassis. Rock the SIMM into a vertical position (see Figure 5-9), using the minimum amount of force required. When the SIMM is properly seated, the socket guide posts fit through the alignment holes, and the locking spring clips click into place.

Step 5 Ensure that each SIMM is straight (perpendicular to the socket), and that the alignment holes (as shown in Figure 5-9) line up with the plastic socket guides on the socket.

1. Insert the SIMM into the socket at an angle from vertical.

2. Push the top of the SIMM down and back.

3. The socket guide posts fit through the holes in the SIMM.

4. The locking springs clip the back of the SIMM.

Caution It is normal to feel some resistance when installing a SIMM, but do not use excessive force on the SIMM, and do not touch the surface components.

Step 6 Repeat Step 3 through Step 5 for each SIMM.

When you finish replacing SIMMs, proceed to the “Replacing the Cover on a Cisco 3620 or Cisco 3640 Router” section on page 5-30 .
