AR-NB2A  UPDATING NETWORK BOX FIRMWARE  5 - 2

4. Updating the firmware

After you select the file, click the Submit button. The firmware is
transmitted to Network Box, and it is updated. The message indi-
cated in Fig.5 blinks repeatedly until the updating process is
completed. Do not turn off the power supply.

[Fig.5: Updating in progress]

5. Restarting your PC

When updating is completed, the message shown in Fig.6
appears on screen. Turn off the power and then turn it on again
to restart Network Box.

[Fig.6: Updating completed]

Note: Both the Boot and Main files can be updated in the same pro-

cedure as mentioned above. However, when you want to
update both at the same time, you need to update them sepa-
rately by repeating the same procedure twice.

Caution: If a DHCP is used, the browser may not be able to reload

automatically in some cases when transferring to the
upload mode because different IP addresses are read.
Therefore, we recommend that you use a fixed IP address
when updating firmware.

If the upload mode is operating with different IP addresses,

check the IP address obtained by the Ethernet address of
Network Box from the DHCP server and display the updat-
ing mode URL again using the browser.

When a proxy server is used, the screen may not be

updated by reloading. In that case, you need to update
manually.
