Removing Cisco Flash Memory SIMMs

Caution New Cisco Flash SIMMs are shipped without preinstalled software. Before replacing a Flash memory

SIMM, be sure to back up the Cisco IOS image to a TFTP server as directed below.

Follow these steps to remove and install an existing Flash memory SIMM:

Step 1 Use the copy flash tftp command in EXEC mode to back up the Cisco IOS image to a TFTP server.

Note For more information about this and related commands, refer to the Cisco IOS configuration

guides and command references. See the “Obtaining Documentation” section on page 38 for

information about these publications.

Step 2 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, avoiding contact with the

connectors.

Step 3 Locate the Cisco Flash memory SIMM sockets on the mainboard. (See Figure 15 through Figure 17.)

Caution Handle SIMMs by the nonconnector edges only; do not press on the center. Handle carefully. SIMMs

are ESD-sensitive components and can be damaged by mishandling.
