Yes. Then the utility starts to upgrade the selected device. If 
the device is a Main Unit, the Main Unit and every Stacking Unit (if 
any) connected to it are upgraded at one time. 
For more details of the Paragon Update utility, see Paragon Manager 
User Guide
. This user guide is available on Raritan website's 
Firmware 
and Documentation section
 
(
). 
Note: Usually the .hex file for updating the firmware of both the Main and 
Stacking Units is the one whose name is “P2-xxx” (xxx represents the 
version) unless you are updating these units for obtaining failsafe 
upgrade feature or it is an update failure case for the Stacking Unit. If so, 
see later sections in this chapter for the appropriate .hex file. 
 
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.

for how to upgrade different devices for failsafe upgrade feature.
