Installing the Equipment
2.3.3 Control Ethernet Connector
The Ethernet control ports are used to connect the
equipment to a PC for access with a web browser. Both
connectors share the same IP address, CTL 1 is the
Primary control port, and is by default the active control
port. Control Port CTL 2 should be considered as the
secondary control network as it will not respond to the
Control Port IP Address unless control has been passed
to it either as a result of a redundancy switch, or via a
user command. The active control port switches when
CTL 1 has no link (e.g. carrier), and CTL 2 has the link.
