Chapter 4: Resetting to Factory Defaults

Home Prev	NetShield 300 Series Getting Started Guide	Next

In some circumstances, it may be necessary to reset the NetShield 300 Series appliance to the state it was in when it left the factory and before it was delivered to a customer. This process is known as a reset to factory defaults or simply a factory reset.

	Caution: cOS Stream upgrades and current configuration are lost
Resetting to defaults means that the default cOS Stream configuration will be restored as well as the original version of cOS Stream that the product left the factory with. The will mean the following: Any cOS Stream upgrades that have been performed since the product left the factory will be lost. An upgrade to a newer cOS Stream version must be repeated. The current cOS Stream configuration will be lost but can be restored if a backup is available.

Caution: cOS Stream upgrades and current configuration are lost

Resetting to defaults means that the default cOS Stream configuration will be restored as well as the original version of cOS Stream that the product left the factory with. The will mean the following:

Any cOS Stream upgrades that have been performed since the product left the factory will be lost. An upgrade to a newer cOS Stream version must be repeated.
The current cOS Stream configuration will be lost but can be restored if a backup is available.

With the NetShield 300 Series, a reset can be done in one of the following ways:

Using the CLI

The CLI can be used by connecting to one of the NetShield 300 Series's Ethernet interfaces using an SSH client over a network. A reset is performed by entering the following command:
```
Device:/> backup -factoryreset
```
Using this command is described further in the separate Administration Guide.

Using the Boot Menu

The boot menu can be accessed through the local CLI console by repeatedly pressing the Esc key while cOS Stream is starting up. The resetting of Ethernet interface IP addresses will not affect the local console connection. The complete procedure is performed with the following steps:
1. Make sure a separate management computer running as a console is attached to the local console port of the NetShield 300 Series.
2. Power up the NetShield 300 Series unit. This may require a restart if the hardware is already powered up.
3. As console output appears, repeatedly press the Esc key before cOS Stream has fully started.
4. The boot menu will now be displayed on the console.
5. Choose the Reset system to factory default option.
Boot menu options are described further in Section 3.4, The Boot Menu and in the separate cOS Stream Administration Guide.

Performing a Reset Manually

The 300 Series can be reset manually with the following steps:
1. The progress of the reset can be followed using a local console connection. If that is required, open a console display window connected to the NetShield 300 Series local console port.
2. While the unit is powered up, push in the recessed reset button on the unit with a suitable pointed tool and keep it pushed in. An opened paper-clip could be used for this.
  
  The button is located next to the power connector and is marked by an inverted solid triangle. It is above the restart button (both are shown below).
3. Continue holding the button in for at least 10 seconds. The status LED will blink and when the blinking stops the reset is being performed.
4. If a console was connected in step 1, the console output will indicate that the hardware has successfully been reset to its factory defaults.
5. After completion of the reset, the NetShield 300 Series unit can now be set up again as though it had never been previously configured.

	Caution: Local console login credentials will be reset
	The local console login credentials will be reset to the default values of username admin and password admin. Changing the cOS Stream admin user password as soon as possible is recommended.
