Main Units 
 
To update Main Units for the Failsafe Upgrade feature 
To obtain the failsafe capability for your Paragon II Main Unit, you must 
follow three major steps. 
  STEP (A): Remove all Stacking Units 
  STEP (B): Upgrade the boot loader 
  STEP (C): Upgrade the firmware code 
Important: During the boot loader upgrade process, the Main Unit's 
settings are not accessible. Therefore, please note down your Main 
Unit's IP address before starting the boot loader upgrade. 
 
STEP (A): Remove all Stacking Units 
1.  Disconnect any Stacking Unit(s) from the Main Unit. 
2.  Set the Main Unit's stacking support to “0.” See 
Stacking Support
 
(on page 42) for additional information. 
3.  The Main Unit restarts itself. 
 
STEP (B): Upgrade the Boot Loader 
Although you may upgrade the Main Unit through TCP/IP, it is highly 
recommended to upgrade the boot loader by connecting the cross-over 
network cable between the Main Unit and the PC with Paragon Update 
to avoid any potential risk. 
1.  Download the appropriate firmware version from Raritan's website. 
See STEP 1: Download the Latest Firmware and Release Notes 
under 
General Update Procedure
 (on page 167) for details. 
2.  Launch the Paragon Update utility: select “R-P2BL-0C4.hex” as the 
firmware update file, and click the “Send To Paragon” button. See 
Paragon Manager User Guide for detailed operation. 
3.  Wait until the upgrade process finishes. 
Important: Interrupting the boot-loader upgrade process could 
result in permanent damage to the system. 
4.  When the update completes, a message “Device Update Successful” 
appears on the PC's monitor. The Main Unit's LCD panel displays 
the following message, which indicates the boot loader is upgraded 
successfully.
