Replacing Flash Memory
Step 4 Beginning with socket 0, insert the DIMM perpendicular to the socket. Push firmly into place, as shown
in step 1 of Figure B-9. When the DIMM is properly seated, the socket guide posts fit through the
alignment holes, and the locking spring clips click into place, as shown in Step 2 of Figure B-9.
Step 5 Ensure that each DIMM is straight (perpendicular to the socket). (See Figure B-9.)
Caution It is normal to feel some resistance when installing a DIMM, but do not use excessive force on the
DIMM, and do not touch the surface components.
Step 6 Repeat Step 3 through Step 5 for each DIMM.
Step 7 Replace the router cover. Follow the instructions in the “Closing the Chassis” section on page B34.
Replacing Flash Memory
Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXM
The system code (router operating system software) is stored in a Flash memory 80-pin single in-line
memory module (SIMM).
Tools Required
You will need the following tools to remove and replace the system-code SIMM on the router:
• Medium-size flat-blade screwdriver (1/4-in. [0.625 cm])
• ESD-preventive wrist strap
• Flash SIMM
Preparing to Install the System-Code SIMM
There is one system-code (Flash memory) SIMM socket on the system board. You can verify how much
Flash memory is already installed in your router by entering the show flash EXEC command.
Caution The system code is stored on the Flash memory SIMM, but new system-code SIMMs are shipped
without preinstalled software. Before continuing with this procedure, use the copy flash tftp EXEC
command to back up the system code to a Trivial File Transfer Protocol (TFTP) server.
