AJAX Hub 2 2G User Manual page 16

Security requirements
Hub 2 needs internet access to connect to the Ajax Cloud service. This is
necessary for the operation of Ajax apps, remote setup and control of the
system, and receipt of push notifications by the users.
The central unit is connected via Ethernet and two SIM cards. The hub is
available in two versions: with 2G and 2G/3G/4G (LTE) modem. We
recommend that you connect all communication channels simultaneously
for more stability and availability of the system.
To connect the hub to Ajax Cloud:
1. Remove the SmartBracket mounting panel by sliding it down with
force. Do not damage the perforated portion, as it is needed to trigger
the tamper protecting the hub from dismantling.
2. Connect power and Ethernet cables to the appropriate sockets and
install SIM cards.
