Flash upgrade

Flash upgrade
Periodically, Eicon Networks may release new versions of firmware for your Shiva
VPN Gateway. If a new version fixes an issue you've been experiencing, or a new
feature you wish to utilize, contact Shiva VPN Gateway technical support for
information on obtaining the latest firmware. You can then load the new firmware with
a flash upgrade.

Before upgrading

Prior performing any firmware upgrade, it is important that you save a back up of your
existing configuration (Advanced > Store/restore all configuration files) to a local file.
While we make every effort to ensure your existing configuration will work with the new
firmware, sometimes compatibility problems will arise. You should be particularly
aware of this possibility when performing a major upgrade.
Note: An upgrade where the minor and/or major revision number is incremented is
considered a major upgrade, e.g. 1.8.5 -> 1.9.2, or 1.9.2 -> 2.0.0, whereas a patch
upgrade increments the patch revision number only, e.g. 1.9.0 -> 1.9.1, or 1.9.0 ->
1.9.2.
Warning: If the flash upgrade is interrupted (e.g. power down), the Shiva VPN
Gateway will stop functioning and will be unusable until its flash is reprogrammed at
the factory or a recovery boot is performed. User care is advised.
After the upgrade has completed successfully and the Shiva VPN Gateway is back up
and running with the new firmware, run through a few tests.
Ensure that Internet connectivity and any VPN connections can be established and
pass traffic, and that any configured services such as DHCP Server, Access Control
or Packet Filtering are functioning as expected.
If you encounter any problems, reset the device to its factory default settings and
reconfigure. You may wish to use your backed up old configuration as a guide in this
process, but do not restore it directly.
If you are upgrading a device that you do not normally have physical access to, e.g.
at a remote or client's site, we strongly recommend that following the upgrade, you
reset the device to its factory default configuration and reconfigure as a matter of
course.
Note: To restore factory default settings, press the black Reset / Erase button on the
rear panel twice.
