Installing the Equipment
2.8.2 Data Ethernet Connector
The unit has four Ethernet ports - two for data input, and
two for data output and will respond to ARPs, pings and
other low-level Ethernet traffic. The ports are accessible
via RJ-45 connectors on the rear panel of the chassis.
These are labeled Ge 1, Ge 2, Ge 3 and Ge 4. Ge 1 and
Ge 2 are used for data input, while Ge 3 and Ge 4 are
data output.

Item Specification
Connector type RJ-45 (100/1000BaseT)
Connector designation Ge 1 /2 Ge 3 /4
Pin outs

Pin 1 - Tx Out(+)
Pin 2 - TX Out (-)
Pin 3 - Rx In (+)
Pin 6 - RX Out (-)
2.8.3 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, Ctrl 1 is the
Primary control port, and is by default the active control
port. Control Port Ctrl 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
Ctrl 1 has no link (e.g. carrier), and Ctrl 2 has the link.
