Re: how to update ASA 5540 ver 8.0.2 to 8.0.3

Here are the upgrade steps:

Download the asa software (asa803-k8.bin)from here:

Download the TFTP server from here:

-Unzip the TFTP server on a computer on the network

-copy the asa803-k8.bin file in the same extracted folder

-doubleclick on tftpd32.exe

-When you click on the 'show dir' button on the tftp server, the asa803-k8.bin file should be one of the listed files

-in the configuration terminal mode of the asa first ping the tftp server computer's ip address (you should be able to get ping responses)

-enter the command 'copy tftp flash'

-enter the ip address of the tftp server computer (press enter)and then enter asa803-k8.bin as the file name (press enter)

-it will ask you 'do you wish to proceed' - press 'y' for yes

-once you are back to the prompt issue the command


asa(config)# sh flash

Directory of flash:/

3 drw- 128 12:40:35 May 07 2006 asa803-k8.bin

7 -rw- 5539756 18:36:21 Jun 07 2006 asdm-521.bin

6 -rw- 1858 12:40:36 May 07 2006 downgrade.cfg

12 -rw- 8202240 18:29:04 Jun 07 2006 asa722-k8.bin

You would see asa803-k8.bin file in the list.


asa(config)# sh run boot

boot system flash:/asa802-k8.bin

This command tells us which file is in the boot system.

We need to change that to 803.bin.

That can be done by the command,

asa(config)#boot system flash:/asa803-k8.bin


'reload' to reboot the asa so that the new software version takes affect

-when the asa boots up again, issue 'show version' command to confirm if the new software is now running on the asa.

DO rate helpful posts.
