14 Licensing
Clicking on the „License“ submenu takes you to licensing. The features of the U 262 can be
upgraded from the factory-delivered state (1 IP TX & 1 IP RX) through to the full complement of
equipment (16 IP TX, 1 IP RX and TS analyzer) by purchasing software licenses.
Figure 17: Input mask for software licenses
A prerequisite for ordering further licenses is provision of the Mac address of the device. The Mac
address can be found either on the sticker on the back of the device (see illustrations on page
3) or in the Web browser interface. In this respect, the lowest Mac address is the important one.
When the Mac address has been provided, ASTRO will generate the license keys and supply
them by E-mail or on CD.
The format of the license keys is a text document (e.g. Lic001772000222.txt). The key or keys can
be inserted into the input mask using „Copy/Paste“, and clicking on the „Submit“ button transfers
the license to the U 262 Gateway. If the license is valid, this is conrmed by a message. An invalid
license is indicated by an error message.
15 Update
15.1 Update using (T)FTP Server
Clicking on the „Update“ submenu takes you to the settings for the U 262 software update. The
„(T)FTP Server address“ line is used to input the (T)FTP server address at which the current
software for the U 262 Gateway is stored.
The „Protocol“ line provides the option of selecting „FTP“ (File Transfer Protocol) or „TFTP“ (Trivi-
al File Transfer Protocol). If the „TFTP“ option is chosen, it is not necessary to input the username
and the password.
„Path“ is used to input the path on which the U 262 software update was stored. It is necessary to
ensure that the software is stored in the indicated path (preceded and followed by „/“), otherwise
the update will not take place. Furthermore, it must be ensured that any rewall installed permits
the (T)FTP communication. In the „Update“ submenu, it is also possible to store the conguration
of the U 262 Gateway on an FTP server, or else to load a conguration into the U 262 Gateway.
Loading a conguration into the U 262 Gateway does not affect the settings of the IP interfaces.
