The IP addresses are used with the DNP, Modbus/TCP, IEC 61580, IEC 60870-5-104, TFTP, HTTP, and PRP protocols.
The next section explains PRP.

REDUNDANCY
• Ports 2 and 3 use the port 2 MAC address, IP address, and mask
• The configuration fields for IP address and mask on port 3 are hidden
• Port 3 is in standby mode and does not actively communicate on the Ethernet network but monitors its link to the Mul-
tilink switch. If port 2 detects a problem with the link, communications is switched to Port 3. Port 3 is, in effect, acting as
a redundant or backup link to the network for port 2. Once Port 2 detects that the link between port 2 and the switch is
good, communications automatically switch back to port 2 and port 3 goes back into standby mode.
If is set to PRP, the operation of ports 2 and 3 is as follows:
REDUNDANCY
• Ports 2 and 3 use the port 2 MAC address, IP address, and mask
• The configuration fields for IP address and mask on port 3 are overwritten with those from port 2. This is visible on the
front panel but not displayed in the EnerVista software.
• Port 2 field is visible
MCST ADDRESS
• The port 2 PTP function still uses only port 2 and the port 3 PTP function still uses only port 3. The relay still synchro-
nizes to whichever port has the best master. When ports 2 and 3 see the same master, as is typically the case for PRP
networks, the port with the better connectivity is used.
The two ports must be connected to completely independent LANS with no single point of failure, such as common
power supplies that feed switches on both LANS.

For this setting change to take effect, restart the unit.

e) FAR-END FAULT INDICATION (FEFI)
Since 100BASE-FX does not support Auto-Negotiation, a Far-End Fault Indication (FEFI) feature is included in UR 7 that
allows for detection of link failures.
The purpose of the Far-End Fault feature is to allow the stations on both ends of a pair of fibers to be informed when there
is a problem with one of the fibers. Without the Far-End Fault feature, it is impossible for a fiber interface to detect a prob-
lem that affects only its transmit fiber.
When the Far-End Fault feature is supported, a loss of receive signal (link) causes the transmitter to generate a Far-End
Fault pattern in order to inform the device at the far end of the fiber pair that a fault has occurred.
