Appliances overview

You can manage multiple email appliances from the page Settings > General > Email Appliances without having to log on to each machine separately. Managed appliances share a single Log Database, from which email log entries, presentation reports, and the dashboard statistics and charts are generated. The Email Security module and all appliances must share supported versions and subscription key for successful communication among the appliances.

An appliance may operate in standalone mode, which is the default mode when an appliance is added to the Email Security module. You can also create appliance clusters by designating an appliance as a primary machine or as a secondary machine associated with a primary machine. See Designating a primary appliance in a cluster.

The Email Appliances page lists all current system appliances in a table that displays information about the appliance and its status, with functionality to switch to a different appliance that is in standalone mode or to remove an unconnected primary

appliance from a cluster. The following table details the functionality on the Email Appliances page:

Option	Description
Hostname	Displays the hostname of the appliance. Selection displays the Edit Appliance page for editing the IP address.
Platform	Displays the appliance platform.
C/E1 interface IP address	Displays the appliance C/E1 interface IP address.
System Connection Status	Displays the appliance connection status.
Mode	Displays the appliance mode.
Action	Displays the actions available for the appliance; N/A, Launch, or Remove. Launch is used to switch to a different appliance; Remove is used to remove an unconnected primary appliance from a cluster. When a primary appliance is removed, all its secondary appliances change to standalone mode. The current and all secondary appliances display “N/A”.
Delete	Selection of the appliance and Delete removes the appliance from the Email Appliances page. An appliance that is being accessed by another user cannot be deleted. Once an appliance is removed from the list, you cannot manage it from the Email Appliances page.
