Operating instructions

Ethernet Ctrl Port Numbering
Both connectors share the same IP address, Ctrl1 is the Primary control port, and is by
default the active control port. Control Port Ctrl2 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 Ctrl1 has no link (e.g. carrier), and Ctrl2 has the link.
Refer to:
Operation and Control >Basic Functions > Ethernet: Control for Control Port Parameters.
NOTE:
This equipment can be controlled using a single control
connection.
