Failsafe Upgrade Feature
In the past, whenever a firmware update failure occurred on the Paragon
II Main Unit, Stacking Unit or a P2-UST user station, a return to Raritan
is required for function restoration. Now Raritan provides the FAILSAFE
upgrade capability, which enables you to restore its function back to
normal by yourself when any update failure occurs.

devices to support the failsafe upgrade feature

The above-mentioned devices in Paragon II version 4.2 or later are
already implemented with the failsafe upgrade feature. If your devices
belong to earlier versions, you can upgrade them with the appropriate
Paragon Update utility (version 2.4.1 or later). See subsequent sections
for how to upgrade different devices for failsafe upgrade feature.
