■
In order to join a Web Appliance to a Sophos Management Appliance, both appliances must
be running the same software engine versions. Check Configuration > System > Updates,
and perform any necessary updates before joining.
■
By default, Sophos Management Appliances are set to Copy configuration and policy data
from the first web appliance to join. When setting up a new group of appliances, be sure
that the first Web Appliance that you join to your Management Appliance is an established
Web Appliance with existing configuration and policy data, otherwise a new Web Appliance
will set your Management Appliance configuration to that of an unconfigured Web Appliance.
1. On the Management Appliance, select Configuration > System > Central Management.
Ensure that these check boxes are selected: Allow Web Appliances to join this Management
Appliance and Copy configuration and policy data from the first web appliance to join.
Then ensure that the Web appliance it is joining to is the established appliance with existing
configuration and policy data.
2. On the stand-alone appliance, select Configuration > System > Central Management.
3. In the Hostname text box, enter the hostname or IP address of the management appliance
to which you want this Sophos Web Appliance joined.
4. In the Join password text box, enter the connection password for the management appliance
to which you want this Sophos Web Appliance joined.
5. Optionally, if this Web Appliance has been in use for a significant period of time prior to joining
to the Management Appliance, and you want to save and use report data, select Upload
historical report data from this appliance to add this appliance’s report data to the
Management Appliance.
Note: If you do not upload historical data, it will be deleted.
6. Click Join Management Appliance.
As the join operation progresses, the icons in the Join status panel change to indicate the
status of each stage of the operation.
Upon a successful join of your Web Appliance to your Management Appliance, the following
changes occur to the administrative web interface:
■
The options on the Configuration > System > Central Management page change to
Revert to Standalone Mode
■
The Reports and Search options are removed from the Navigation bar
■
The Configuration pages are reduced in number and some are simplified in content.
To access any of these removed features, see the administrative web interface of the
Management Appliance, which is where that functionality is now controlled.
4.4.10.2 On a Joined Web Appliance: Reverting to Standalone Mode
Use the Configuration > System > Central Management page on a joined Web Appliance to
revert to standalone mode.
1. Click Revert to Standalone Mode.
A verification dialog box is displayed, prompting you to confirm that you want to break the
connection with the Management Appliance to resume in standalone mode.
