118 PARAGON II USER GUIDE
Before upgrading the Stacking Units, ensure these requirements are met.
• The Stacking Units are properly connected to the Main Unit and powered on.
• The “Stacking Support” setting in the Main Unit corresponds to the number of connected
Stacking Units, that is, if there are three Stacking Units connected to the Main Unit, set the
setting to 3. See the “Stacking Support” section under Paragon II Front Panel Display and
Controls in Chapter 2 for
additional information.
• The value of the “Set Stack ID” setting in every connected Stacking Unit is unique: 1 up to 3.
See Installing the Paragon P2-UMT832S Stacking Unit in Chapter 2 for additional
information.
Note: For “special” firmware upgrade involving the boot loader or failsafe feature, only one
Stacking Unit is allowed to be connected to the Main Unit at one time. Refer to the Stacking
Units section of Failsafe Upgrade Feature later in this chapter for more information.
STEP 4: Launch the Paragon Update Utility
Specify the device(s) to upgrade and the appropriate firmware in the Paragon Update utility. Note
that Paragon Update utilized to upgrade devices must be the latest version which is extracted
from the downloaded firmware’s ZIP file. Its filename is “ParagonUpdate_XXX.exe” (XXX
represents the version). This is to ensure the upgrade is performed successfully.
1. Double click “ParagonUpdate_XXX.exe.”
2. Enter the information of the device that you want to upgrade in the Paragon Update utility,
including the device’s name, IP address or the number of the serial port where the device
connects, etc.
3. Select the device by checking its check box (
).
4. Click Load Hex File and navigate to select the appropriate firmware file.
5. Click Send To Paragon.
6. Click 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 the same time.
For details on the operation of the Paragon Update utility, see Paragon Manager User Guide.
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,
please refer to 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.
The following table lists the firmware and/or boot loader versions required for different devices to
support the failsafe upgrade feature.
DEVICE REQUIRED VERSION
Main Unit Firmware version: Any version after 3B0K
Boot Loader version: 0C4 or later
Stacking Unit Main Unit’s Firmware version: 3E5 or later
Stacking Unit’s Boot Loader version: 0C5 or later
