Network and System Management

To reset the UTM to the original factory default settings, you can use one of the following two 
methods:

•

Using a sharp object, press and hold the Reset button on the rear panel of the UTM (see 

) for about eight seconds until the Test LED turns on and begins to blink 

(about 30 seconds). To restore the factory default configuration settings without knowing the 
administration password or IP address, you must use the Reset button method.

•

On the Backup & Restore Settings screen (see 

), next to Revert to 

factory default settings, click the default button.

The UTM reboots. If you use the software default button, the Backup & Restore Settings screen 
remains visible during the reboot process. The reboot process is complete after several minutes 
when the Test LED on the front panel goes off. 

The UTM can automatically detect any new firmware version from NETGEAR. The firmware 
upgrade process for the UTM consists of the following stages that are explained in detail in the 
sections below:

1. Querying the available firmware versions.

2. Selecting a firmware version to download directly to the UTM (that is, not first to a computer 

and then to the UTM).

3. Installing the downloaded firmware version.

4. Rebooting the UTM with the new firmware version.

Warning: When you push the hardware Reset button or click the software default 

button, the UTM settings are erased. All firewall rules, VPN policies, LAN/
WAN settings, and other settings are lost. Back up your settings if you intend 
on using them.

Note: After rebooting with factory default settings, the UTM’s password is password and 

the LAN IP address is 192.168.1.1.
