Chapter 12: Firmware Upgrade
169
STEP (C): (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 also 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 the Main Unit in one single operation.
Before upgrading the Stacking Units, ensure these requirements are met.
• The Stacking Units are properly connected to the Main Unit and
turned 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
Stacking Support (on page 41) for additional information.
• The value of the “Set Stack ID” setting in
every connected Stacking
Unit is unique: 1 up to 3. See Installing a P2-UMT832S Stacking
Unit (on page 29) 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. See the Stacking Units (on page 172) section of Fail
safe
Upgrade Feature (on page 170) for more information.
STEP (D): 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 downloaded along with the firmware.
This is to ensure the upgrade is performed successfully. The update
utility's filename is “ParagonUpdate_xxx.exe” (xxx represents the
version).
To launch the Paragon Update utility
1. Double click “ParagonUpdate_xxx.exe.” The Paragon Update window
appears.
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, and so on.
3. Select the device by selecting its checkbox (
).
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 one time.
