c4710ace-mz.A3_1_0.bin using FTP, enter:
ACE-1/Admin# copy ftp://server1/images/c4710ace-mz.A3_1_0.bin image:
Enter source filename[/images/c4710ace-mz.A3_1_0.bin]?
Enter the destination filename[]? [c4710ace-mz.A3_1_0.bin] File already exists, do you

command in Exec mode. For example, enter:
ACE-1/Admin# dir image:c4710ace-mz.A3_1_0.bin

176876624 Jun 9 14:15:31 2008 c4710ace-mz.A1_8_0A.bin
Check the MD5 checksum of the new software image on both ACEs to ensure that the new image is the
Step 7
same as the image posted on Cisco.com. For example, enter:
ACE-1/Admin# show file image:c6ace-t1k9-mz.A2_3_0.bin md5sum
Configure ACE-1 to automatically boot from the new image. To set the boot variable and configuration
Step 8
register to 0x1 (perform auto boot and use startup-config file), use the boot system image: and
config-register commands in configuration mode. For example, enter:
ACE-1/Admin# config
ACE-1/Admin(config)# boot system image:c4710ace-mz.A3_1_0.bin
ACE-1/Admin(config)# config-register 0x1
ACE-1/Admin(config)# exit
ACE-1/Admin#
You can set up to two images through the boot system command. If the first image fails, the ACE tries
to boot from the second image.
Note
Verify that the boot variable was synchronized with ACE-2 by entering the following command on
Step 9
ACE-2:
ACE-2/Admin# show bootvar
BOOT variable = "disk0:/c4710ace-mz.A3_1_0.bin;
disk0:/disk0:c4710ace-mz.A1_8_0A.bin"
Configuration register is 0x1
