IX Software Upgrade
You may easily upgrade X7868r/X7868r+embedded software by
obtaining the compressed upgrade kit from the service provider and
then following the steps for upgrading through either a DOS prompt
or a Web-browser:
Software upgrade through a DOS prompt
Step 1. Extract the ZIP file for updated firmware.
Step 2. Connect X7868r/X7868r+via the local Ethernet port or
remote ADSL link, making sure that the X7868r/X7868r+
Ethernet IP address and your terminal are properly
configured so that you can successfully “ping”
X7868r/X7868r+. The default local IP address is
“192.168.1.1”.
Step 3. Under the DOS prompt, execute the command “xupgrade
<IP address of X7868r/X7868r+>”, for instance, “xupgrade
192.168.1.1”.
Step 4. This upgrading process may last as long as 60 seconds.
Step 5. Reboot X7868r/X7868r+with new software.
Note: Strictly maintain stable power to X7868r/X7868r+while upgrading
its software. If the power fails during the upgrading process, contents in
the memory could be destroyed, and the system may hang. In such a
case, you must call the dealer or system integrator for repairs.
