Step 1 
Make the new software image available on a TFTP server, or make the MSFC a TFTP server by using this command:
msfc(config)# tftp-server bootflash:image name
Step 2 If the MSFC is the TFTP server, make sure you have a VLAN interface on the MSFC reachable from the module. For example:
a. On the MSFC, enter these commands:
router(config)# interface Vlan30
router(config)# description to_fwsm_vlan_30
router(config)# ip address 10.20.30.2 255.255.255.0
router(config)# no ip redirects
b. On the module, enter these commands:
nameif vlan30 inside security100 ... ip address inside 10.20.30.5 255.255.255.0 c. From the module make sure that you can ping the MSFC, by entering this command:
FWSM# ping 10.20.30.2
10.20.30.2 response received -- 0ms 10.20.30.2 response received -- 0ms 10.20.30.2 response received -- 0ms Step 3 From the module enter the copy tftp flash command:
FWSM# copy tftp flash
Address or name of remote host [127.0.0.1]? 10.20.30.2 Source file name [cdisk]? c6svc-fwm-k9.1-1-0-207.bin copying tftp://10.20.30.2/c6svc-fwm-k9.1-1-0-207.bin to flash:image [yes|no|again]?yes
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The output shows the MSFC as the TFTP server.
Step 4 Reload the module by entering this command:
FWSM# reload
