This is particularly useful should the CyberGuard SG appliance become uncontactable,
e.g. due to misconfiguration.
Pushing the reset button twice clears all stored configuration information, reverts all
settings to the factory defaults, and reboots the CyberGuard SG appliance.
Note
When the CyberGuard SG appliance reboots, it has an IP address of 192.168.0.1,
netmask 255.255.255.0.
Disabling the reset button on your CyberGuard SG PCI appliance
For convenience, the CyberGuard SG appliance ships with the rear panel Reset button
enabled. This allows the CyberGuard SG appliance’s configuration to be reset to factory
defaults.
From a network security standpoint, it may be desirable to disable the Reset switch after
initial setup has been performed. This is accomplished by removing the jumper linking
CON2 on the CyberGuard SG appliance.
This jumper is labeled Remove Link to Disable Erase.
Flash upgrade
Periodically, CyberGuard may release new versions of firmware for your CyberGuard SG
appliance. If a new version fixes an issue you’ve been experiencing, or contains a new
feature you wish to utilize, contact CyberGuard SG technical support for information on
obtaining the latest firmware. You can then load the new firmware with a flash upgrade.
Note
Please read the appendix entitled Firmware Upgrade Practices and Precautions before
attempting a firmware upgrade.
There are two primary methods available for performing a flash upgrade, Netflash and
Flash upgrade via HTTP. Remote upgrades may also be performed using TFTP if you
have a TFTP server at the remote site, see Flash upgrade via TFTP.
