100 PARAGON II USER GUIDE
STEP 3: 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. This is to ensure the upgrade is performed successfully.
For details on the operation of the Paragon Update utility, see Paragon Manager User Guide.
Failsafe Upgrade Feature
In the past, whenever a firmware update failure occurred on the Paragon II Main Switching 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 Switching Unit Firmware version: Any version after 3B0K
Boot Loader version: 0C4 or later
Stacking Unit Main Switching Unit’s Firmware version: 3E5 or
later
Stacking Unit’s Boot Loader version: 0C5 or later
P2-EUST User Station Any version
P2-UST User Station Firmware version: 1F9 or later
Note: Boot Loader is displayed as “F/W Loader” on the front LCD panel.
The abovementioned devices in Paragon II 4.2 are already implemented with the failsafe upgrade
feature. If your devices belong to earlier versions, you can simply upgrade them with the
appropriate Paragon Update utility (version 2.4.1 or later). See next sections for how to upgrade
different devices for failsafe upgrade feature.
Main Switching Units
Updating Main Switching Units for Failsafe Upgrade Feature
To obtain the failsafe capability for your Paragon II Main Switching Unit, you must follow three
major steps.
STEP 1: Remove the Stacking Units
STEP 2: Upgrade the boot loader
STEP 3: Upgrade the firmware code
Important: During the boot loader upgrade process, it is not accessible to the Main
Switching Unit’s settings. Therefore, please note down your Main Switching Unit’s IP
address before starting the upgrade process.
STEP 1: Remove the Stacking Units
If any Stacking Unit(s) is connected to the Main Switching Unit, remove all of them.
1. Disconnect any Stacking Unit(s) from the Main Switching Unit.
2. Set the Main Switching Unit’s stacking support to “0.” See the “Stacking Support” section
under Paragon II Front Panel Display and Controls in Chapter 2 for additional information.
3. The Main Switching Unit restarts itself.
