CAUTION: The redundant patch cables interconnecting the Director devices
are critical links required for the operation of the Director group. The two
inter-Director device links must remain connected when the Director devices
are online. Although a single inter-Director device can lose a link and regain
its connection, the loss of both inter-Director device links causes one of the
Director devices to become isolated from the Director group. In
