5 SOFTWARE UPGRADE PROCEDURE
The application software is field upgradable. The upgrade procedure and the required equipment
is described in the following section.
Note that once the system is up, it is controlled by an executing application image residing in the
flash memory. No software upgrade is possible during this mode. The upgrade can only be done
when the system is resetting. To initiate this sequence, the user must set the “boot mode”
configuration parameter to “Boot from Net” during normal operation, and then perform a “reset”.
When the Boot-from-NET option is set, Bootstrap can start the system with an image residing on a
TFTP server on the network. In such a setup, a console terminal is connected to the console port,
and a TFTP server in the network is connected to one of the Ethernet ports. A network can be as
simple as an Ethernet Hub.
The upgrade procedure is as follow:
1. Use HTTP or FTP to download the new version firmware from our website.
2. Enter password in the "Password" edit box.
3. Enter the file downloaded in the "File Path" edit box. (You can use "Browse" button to select
the file.)
4. Press the "Upgrade" button.
Note:
After you have successfully upgraded the new firmware, please reboot the system so that
the new firmware will take effect.
