Follow the procedures described in General Update Procedure in this
chapter to upgrade the
Main Unit with the latest firmware whose name is “P2-XXX.hex” (XXX represents the version).
Verify the Firmware Version
Use the Function Menu on the Front Panel to check the firmware version. See Paragon II Front
Panel Display and Contr
ols in Chapter 2 for more information.
Recovering Main Units after Upgrade Failure
When any upgrade failure takes place, you can sim
ply return the function back to normal with the
Main Unit’s failsafe capability

1. Check the Front Panel LCD display to see whether the Main Unit enters the boot loader mode
as shown below:

If not, press and hold Y and Z on the Front Panel of the Main Unit simultaneously, and
power cycle the Main Unit at the same time. This forces it to enter the boot loader mode.
2. Repeat the same upgrade procedure: activate the Paragon Update utility again, select the
same firmware file that was chosen when the upgrade failure occurred, and click the “Send
To Paragon” button. For details on the operation of the Paragon Update utility, see Paragon
Manager User Guide.
