Memory Replacement Procedures Replacing Shared-Memory SIMMs Follow this procedure if you are replacing the 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 Router Internal Components" earlier in this chapter. Step 4 Remove and safely store all the network processor modules present as described in "Removing Network Processor Modules"earlier in this chapter for later reinstallation. Step 5 Locate the shared-memory SIMM card socket shown on the left of the motherboard as shown in Figure 5-5 (for the Cisco 4000-M) and Figure 5-6 (for the Cisco 4500-M and Cisco 4700). Step 6 Turn the chassis so that the rear of the chassis is closest to you. 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 5-9.) 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 Steps 7 and 8 for each SIMM.

Memory Replacement Procedures
Replacing Shared-Memory SIMMs
Follow this procedure if you are replacing the 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 Router Internal
Components” earlier in this chapter.
Step 4
Remove and safely store all the network processor modules present as described in
“Removing Network Processor Modules”earlier in this chapter for later reinstallation.
Step 5
Locate the shared-memory SIMM card socket shown on the left of the motherboard as
shown in Figure 5-5 (for the Cisco 4000-M) and Figure 5-6 (for the Cisco 4500-M and
Cisco 4700).
Step 6
Turn the chassis so that the rear of the chassis is closest to you.
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 5-9.)
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 Steps 7 and 8 for each SIMM.
Step 10
Proceed to the next section, “Inserting Shared-Memory SIMMs.”
