Note:

For the STM150 only, there is an alternate way to return the settings to factory defaults: Using a sharp object, press and hold the Reset button on the rear panel of the STM150 (see

Rear Panel STM150

on page 20) for about 10 seconds until the front panel Test LED flashes

and the STM150 returns to factory default settings.

Updating the Software

If you have used the Setup Wizard, you might have already configured the software update settings; the Software Update screen allows you to modify these settings.

The STM has four main software components:

•

The application software that includes the network protocols, security services, Web

Management Interface, and other components.

•

A scan engine that enables the STM to scan emails, attachments, Web files, and applications, and that functions in conjunction with the pattern file.

•

A pattern file that contains the virus signature files and virus database.

•

An operating system (OS) that includes the kernel modules and hardware drives.

The STM provides two methods for updating components:

•

Scheduled, automatic update

•

Manual update

Because new virus threats can appear any hour of the day, it is very important to keep both the pattern file and scan engine firmware as current as possible. The STM can automatically check for updates, as often as every 15 minutes, to ensure that your network protection is current.

Scheduling Updates

Enabling scheduled updates ensures that the STM automatically downloads the latest components from the NETGEAR update server.
