Flash Upgrade - Secure Computing SG300 User Manual

Disabling the reset button on your SG PCI appliance
For convenience, the SG unit ships with the rear panel Reset button enabled. This
allows the SG unit'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 SG unit.
This jumper is labeled Remove Link to Disable Erase.

Flash upgrade

Periodically, Secure Computing may release new versions of firmware for your SG unit.
If a new version fixes an issue you've been experiencing, or contains a new feature you
wish to utilize, contact 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.
During the upgrade, the front panel LEDs on the SG unit flash in an in-and-out pattern.
The SG unit retains its configuration information with the new firmware.
Warning
If the flash upgrade is interrupted (e.g. power down), the SG unit stops functioning and
becomes unusable until its flash is reprogrammed at the factory or a recovery boot is
performed. User care is advised.
For instructions on performing a recovery boot, refer to Appendix D, Recovering From a
Failed Upgrade.
