Updating the Appliance Automatically
Introduction Use the Update Settings page to configure the appliance to automatically check for and
install updates. Define the following settings to configure automatic updates for the
appliance:
● when to check for updates
● when to download and install security updates
● when to download firmware updates
● how and when to install firmware updates
● which firmware update version(s) to install
Note: When you install a firmware update, the appliance may lose link temporarily.
Example Let’s say you want to configure the appliance to check for updates daily at 3:00 A.M. If it
finds any updates (either firmware or security updates), you want it to automatically
download all of the updates, and then install the security updates immediately. As the
final steps, at 5:00 A.M., you want the appliance to automatically perform a system
backup and then install the available firmware updates.
The following table describes the appliance update process with these settings:
Stage Description
1 At 3:00 AM, the appliance checks the ISS Download Center for updates.
2 The appliance downloads security and firmware updates.
3 The appliance installs security updates immediately.
4 At 5:05 AM, the appliance does the following:
• reboots, and then creates a system backup
• installs the firmware update, and then reboots if necessary
