Chapter 7: Resetting to Factory Defaults

Home Prev	NetWall W50 Getting Started Guide	Next

In some circumstances, it may be necessary to reset the NetWall W50 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 Core upgrades and current configuration are lost
Resetting to defaults means that the default cOS Core configuration will be restored as well as the original version of cOS Core that the product left the factory with. The will mean the following: Any cOS Core upgrades that have been performed since the product left the factory will be lost. An upgrade to a newer cOS Core version must be repeated. The current cOS Core configuration will be lost but can be restored if a backup is available.

Caution: cOS Core upgrades and current configuration are lost

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

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

With the NetWall W50, a reset can be done in one of the following ways:

Using the Web Interface

A reset is possible through a web browser over a network connection using the cOS Core Web Interface (WebUI). The steps to do this are the following:
1. Open a web browser and enter the IP address of the management interface. The cOS Core web interface login dialog should be displayed. Connecting with a browser is described further in Section 3.4, Management Computer Connection.
2. Log into cOS Core as an administrator.
3. Go to: Status > Maintenance > Reset & Restart
4. Select the option: Reset the entire unit to factory defaults.
5. Press the Reset button.
Note that this will reset all the IP addresses on Ethernet interfaces to their defaults which might mean that the network connection will be lost.

Using the CLI

The cOS Core CLI can be used by connecting to one of the NetWall W50's Ethernet interfaces using an SSH client over a network. A reset is performed by entering the reset -unit command twice in succession:
```
Device:/> reset -unit
Device:/> reset -unit
```
Entering the command twice is a safeguard against accidental use. Note that, like using the Web Interface method above, this will reset all the IP addresses on Ethernet interfaces to their defaults which may mean that the SSH connection will be lost.

Using the Boot Menu

The boot menu can be accessed through the local CLI console by pressing any console key while cOS Core is starting up. The resetting of Ethernet interface IP addresses will not affect the local console connection. A factory reset using the boot menu 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 NetWall W50.
2. Power up the NetWall W50 unit. This may require a restart if the hardware is already powered up.
3. As console output appears, press any console key before cOS Core has fully started.
4. The boot menu will now be displayed on the console.
5. Choose the menu item Reset Options.
6. Various reset options are now displayed on the console. For a full reset, select the menu option Reset to Factory Defaults.
A complete description of the boot menu and all its options can be found in the separate cOS Core Administrators Guide.

Performing a Reset Manually

The W50 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 NetWall W50 local console port.
2. Power off the NetWall W50.
3. Push in the recessed reset button on the NetWall W50 with a suitable pointed tip tool and keep it pushed in. A suitable paper-clip could be used to do this.
4. Power up the unit while still holding the reset button in.
5. Continue holding the button in for at least 30 seconds longer after the power is applied.
6. If a console was connected in step 1, the console output will indicate that the hardware has been reset to its factory defaults.
7. After completion of the reset, the NetWall W50 can now be set up as though it had never been previously configured.

	Caution: The local console password is reset to no password
	If a local console password was set previously, this will also be reset to the factory default of having no password set. If required, a local console password can be set by choosing the boot menu option Enable Console Password.
