Replacing Shared-Memory SIMMs

Step 7 The SIMMs are held in place at each end by small metal spring clasps. To remove

a shared memory SIMM, push the two metal clasps apart. Angle the SIMM

upward and pull it out. (See Figure C-5.)

Caution Do not exert pressure on the components on the SIMM surface because it might

damage them. The sides of the SIMM must clear the metal clasps before the SIMM can be

safely removed.

Step 8 Place the removed SIMM in an antistatic bag to protect it from ESD damage.

Step 9 Repeat Step 7 and Step 8 for each SIMM.

Step 10 Proceed to the next section, “Installing Shared-Memory SIMMs.”

Installing Shared-Memory SIMMs

Take the following steps to install shared-memory SIMMs:

Step 1 Unplug the chassis power cord and network connections.

Step 2 Put on 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 3 Remove the chassis cover as described in the section “Accessing the Internal

Components of the Router” in the chapter “Conﬁguring the Cisco 4000 Series

Chassis.”

Step 4 Find the shared-memory SIMM card socket locations on the left of the

motherboard (as aligned in Figure C-1 and Figure C-2). All the sockets should be

empty. If not, remove the shared-memory SIMMs following the procedures in the

previous section “Removing Shared-Memory SIMMs.”

Step 5 Turn the chassis so that the side with the shared-memory SIMM cards is closest to

you.

Step 6 Hold the SIMM with the connector edge at the bottom, with the component side

facing you, and the polarization notch on the left. (See Figure C-6.)
