Managing BlackBerry device access to the BlackBerry Enterprise Server

You can use the Enterprise Service Policy to control which BlackBerry® devices can connect to a BlackBerry® Enterprise Server.

By default, after you turn on the Enterprise Service Policy, the BlackBerry Enterprise Server permits connections from any

BlackBerry device or BlackBerry enabled device that you previously associated with the BlackBerry Enterprise Server. The

BlackBerry Enterprise Server also prevents connections from any BlackBerry device that you associate with the BlackBerry

Enterprise Server after you turn on the Enterprise Service Policy.

You can configure an allowed list to determine which BlackBerry devices can access a BlackBerry Enterprise Server. A BlackBerry

device that meets the criteria that you specify in the allowed list can associate with the BlackBerry Enterprise Server when the

BlackBerry device activates over the wireless network.

You can define the following types of criteria:

• specific BlackBerry device PINs

• range of BlackBerry device PINs

• specific manufacturers

• specific BlackBerry device models

The BlackBerry Administration Service includes lists of permitted manufacturers and models of BlackBerry devices that you

associated with the BlackBerry Enterprise Server previously.

You can permit a user to override the Enterprise Service Policy so that a BlackBerry device or BlackBerry enabled device can

connect to the BlackBerry Enterprise Server even if you configure the allowed list with criteria that exclude that BlackBerry device

or BlackBerry enabled device.

For more information, see the BlackBerry Enterprise Server Administration Guide.
