Users can later upgrade their MG 3200 features, capabilities and quantity of available
resources by specifying what upgrades they require and the corresponding TPM's serial
number (or MAC address), and ordering a new key to match their specification.
The Software Upgrade Key is sent as a string in a text file, to be loaded into the MG 3200.
Stored in the MG 3200's non-volatile flash memory, the string defines the features and
capabilities allowed by the specific key purchased by the user. The MG 3200 allows users
to utilize only these features and capabilities. A new key overwrites a previously installed
key.
Note:
8.4.6.3.2 Backing up the Current Software Upgrade Key
Back up your current Software Upgrade Key before loading a new key to the MG 3200.
You can always reload this backed-up key to restore your MG 3200 capabilities to what
they originally were if the 'new' key does not comply with your requirements.
To backup the current Software Upgrade Key, take these 5 steps:
1. Launch the MG3200 Web GUI (for details on how to lauch the Web GUI, refer to
"Accessing the Embedded Web Server" on page 144).
2. Click the Software Update button.
3. On the sub-menu bar on the top, click the Software Upgrade Key link (Note: on older
version, it is the License link). The Software Upgrade Key screen is displayed (shown
in the figure, 'Software Upgrade Key Screen' below).
4. Copy the string from the Current Key field and paste it in a new text file on your PC
machine.
5. Save the text file with a name of your choosing in any folder on your PC, as long as
you remember how to reaccess the data should it be needed later.
8.4.6.3.3 Loading the Software Upgrade Key
After receiving the Software Upgrade Key file (do not modify its contents in any way),
ensure that its first line is [LicenseKeys] and that it contains one or more lines in the
following format:
S/N<Serial Number of TPM> = <long Software Upgrade Key>
For example: S/N370604 = jCx6r5tovCIKaBBbhPtT53Yj...
One S/N must match the S/N of your MG 3200 module (TPM). The MG 3200's S/N can be
viewed in the Device Information screen (refer to ''Device Information'' on page 188).
You can load a Software Upgrade Key using:
The Embedded Web Server (refer to ''Loading the Software Upgrade Key Using the
Embedded'' below).
The BootP/TFTP configuration utility (refer to ''Loading the Software Upgrade Key
Using BootP/TFTP'' on page 83).
The EMS (refer to the EMS User's Manual or EMS Product Description).
Version SN09
The Software Upgrade Key is an encrypted key. Each TPM utilizes a unique
