System-Code SIMM Replacement
To replace the system-code Flash memory SIMM:
Step 1
If you have not already done so, enter the copy flash tftp EXEC command 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 B2
.
Step 6
Locate the system-code SIMM on the system card. (See
Figure B-5
.)
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 B-11
.)
Caution
To prevent damage, do not press on the center of the SIMM. Handle each SIMM carefully.
