Chapter 8: Firmware Upgrade
To incorporate the newest Paragon II features, you can upgrade Paragon II Main Units, Stacking
Units and user stations with the latest firmware on Raritan’s Website. Upgrade can be done via
network or the RS-232 connection.
General Update Procedure
Procedures for firmware upgrade of the Paragon II Main Unit, Stacking Unit, and user stations
(P2-UST, P2-EUST or P2-EUST/C) all include these major steps.
STEP 1: Download the latest firmware and release notes
STEP 2: Verify the connection between the device and the PC running Paragon
Update
STEP 3: (Optional) Verify the Stacking-related configuration
STEP 4: Launch the Paragon Update utility
STEP 1: Download the Latest Firmware and Release Notes

our browser to visit Raritan’s Firmware Upgrades Web page:
http://www.raritan.com/support/firmwareupgrades
.
2. Click Paragon II to locate the latest firmware version for the device you want to upgrade.
3. Click that firmware.
4. Click START DOWNLOAD.
5. Click Save and specify the location to save the file.
6. After the download completes, unzip the downloaded file. The extracted files include the
newest Paragon Update utility, .hex files, etc. The .hex file is a firmware file.
7. For some versions, such as version 4.2, the associated release notes are not covered in the
downloaded firmware file, so locate the release notes and download it by repeating Steps 4 to
6.
8. Read the release notes for any necessary information.
STEP 2: Verify the Connection between the Device and the PC Running
Para
gon Update
The device intended to upgrade must be connected to the PC that will run the Paragon Update
utility. There are two types of connections depending on your device.
• Network: If your device comes with a LAN port, such as Paragon II Main Unit, upgrade it by
connecting it to the network and assigning an IP address to it. However, for Paragon II
Stacking Unit, it must be upgraded by connecting to the Main Unit which is connected to the
network.
• RS-232 Cable: For those devices without the network port, such as user stations, this is the
only method to upgrade them. Connect the device to one of the serial ports of the PC that runs
the Paragon Update utility via the RS-232 cable.
Note: One DB9 male-to-female serial (RS-232) cable is shipped with the user station. It is a
direct cable that can be used to upgrade the firmware with TXD, RXD and GND signals.
STEP 3: (Optional) Verify the Stacking-Related Configuration
This step is
necessary when any Stacking Unit is connected to the Main Unit and the firmware
upgrade of Stacking Units is desired. For regular firmware upgrade which does not involve the
boot loader or failsafe feature, Paragon allows you to update the Main Unit and “ALL” Stacking
Units that are connected to it in one single operation.
