Upgrading the Firmware 172

NOTE: Do not upgrade the router firmware unless you are told to do so by technical

support staff.

NOTE: It is recommended that you save all configuration changes and restart the unit to

implement them before you upgrade the router firmware.

To upgrade the router firmware:

1. In the Main Menu, click Diagnostics, and then click Upgrade Router. The Router

Upgrade

screen opens:

Figure 171: Router Upgrade screen

2. Under Upgrade URL, fill in the location of the new firmware file. For example,

http://www.ru.com/ru.tgz. (Note: This is not the actual URL to use; consult your

distributor for information about the correct URL.)

3. Click Update. The new firmware is uploaded to the unit and then the router firmware is

updated.

The upgrade process itself – once the file upload is completed – takes approximately

three minutes. A timer indicates when the upgrade is completed. When it is completed,

the

System Summary screen is displayed. If this screen is not displayed within about six

minutes of the end of the file upload, and you cannot connect to the unit via a client

application or through the configuration utility, restart the unit by disconnecting it from

the power supply and then reconnecting it. Bear in mind that interrupting the upgrade

process before it is completed may cause the router to become completely inoperable, so

do not restart the unit before the six minutes have passed. Note that if you are using a

WiFi or cellular connection to upgrade the router firmware, it may take longer for the

unit to reestablish the connection to the network.
