Replacing Flash Memory
Figure 11 Removing and Replacing the System-Code SIMM
Step 8 Position the new SIMM so that the polarization notch is located at the left end of the SIMM socket.
Caution To prevent damage, note that some Flash memory SIMMs have the components mounted on the rear
side; therefore, when inserting the SIMM, always use the polarization notch as a reference and not
the position of the components on the SIMM.
Step 9 Insert the new SIMM by sliding the end with the metal fingers into the SIMM connector socket at
approximately a 90º angle to the system card. Gently rock the SIMM back into place until the latches on
both sides snap into place. Do not use excessive force because the connector might break.
Step 10 Replace the router cover following the procedure in the “Closing the Chassis” section on page 34.
