Recovery
In the unlikely event that there is a hard disk crash, use the Recovery window to
configure a recovery diskette to restore the software image and file system to the
hard drive of the VPN Router. The recovery diskette is included with your VPN
Router. You can also use this window to create additional copies of the recovery
diskette, as well as to reformat a diskette.
Accessing the diskette drive
If the VPN Router has a front cover, you must remove it to gain access to the
diskette drive. See the installation guide for details on how to remove the front
cover. Booting the VPN Router with the recovery diskette does the following:
• reformats the hard disk
• allows FTP access to the hard disk
• restores the previously backed-up software image and file system from a
backup host to the hard disk
• downloads a new factory default software image and file system from a file
server to the hard disk
These utilities are accessed throught Hypertext Transfer Protocol (HTTP) after it
is booted from the recovery diskette.
Using the recovery diskette
To use the recovery diskette:
1 Remove the VPN Router’s front cover.
2 Insert the recovery diskette into the drive and press Reset on the back of the
VPN Router.
Note: The VPN Router 1000, 1010, 1050, and 1100 do not have a
floppy drive in the unit. Although the VPN Router 600 does not have a
floppy drive, the recovery image is stored in a PROM and you can
invoke it by pressing a switch on the back of the unit.
