and Table 7 show the part numbers for the SIMMs.

Flash SIMM Replacement
To replace the system-code flash memory SIMM:
Step 1 If you have not already done so, enter the copy flash tftp command in privileged EXEC mode to back
up the system code.
Step 2 Power off the router.
Step 3 Remove all cables from the rear panel of the router.
Step 4 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.
Step 5 Open the chassis cover following the procedure in the “Removing the Chassis Cover” section on page 2.
Step 6 Locate the system-code SIMM on the system card. (See Figure 11.)
Step 7 If necessary, remove the existing system-code SIMM by pulling outward on the connector holders to
unlatch them. The connector holds the SIMM tightly, so be careful not to break the holders on the SIMM
connector. (See Figure 11.)
Caution To prevent damage, do not press on the center of the SIMM. Handle each SIMM carefully.
