IP NETWORK
CONFIGURATION
This page allows basic IP configuration, identifying the current device on the IP network.
If your network has a DHCP server, click the Automatic (DHCP) box. You can then use BACnet discovery to
list controllers along with their IP addresses, and can use the hostname to identify the IP address of a
specific controller. By default, all CBXi devices leaving the factory are configured to use DHCP, and have a
hostname set to “
CBXi
” followed by the controller’s serial number – e.g.
CBXi901004A
If your network does not have a DHCP server, then the CBXi controller will use a default IP address, which
is made up as follows:
• The first byte of the IP address is set to
10
• The 6 digits of the numerical part of the serial number grouped into 3 sets of 2 digits to form the last
3 bytes of the IP address.
For example, CBXi with serial number
901001A
will be allocated the default IP address of
10.90.10.01
. See

Configuring the IP connection
on page 31. The IP Address input is also used to specify the subnet
mask in CIDR format. See
Subnetwork (Subnet)
on page 7 for a full explanation.
Recovery IP Address
If the primary IP cannot be reached – for example if the primary is set to automatic and there is no DHCP
server available, then the user must use the Recovery IP Address to access the Web UI and properly
configure the primary. The recovery is only designed for access to the web UI.
The factory default value is based on the serial number in the same way as the primary, but the Recovery
IP Address should not be changed or disabled unless it interferes with other network operations.
