CHAPTER 5: SETTINGS
5.3.4.4 Network
As outlined in the previous section, when using more than one Ethernet port, configure each to belong to a different
network or subnet using the IP addresses and mask. Configure the network IP and subnet settings before configuring the
routing settings.

The IP addresses are used with the DNP, Modbus/TCP, IEC 61580, IEC 60870-5-104, TFTP, HTTP, and PRP protocols. PRP is
explained in its own section later.
— This setting sets the port's IPv4 address in standard IPV4 format. This setting is valid on port 3 if
PRT1 (2 or 3) IP ADDRESS
port 2 is set to None.
REDUNDANCY
— This setting sets the port's IPv4 subnet mask in standard IPV4 format. This setting is valid on
PRT1 (2 or 3) SUBNET MASK
port 3 if port 2 is set to None.
REDUNDANCY
— Determines if ports 2 and 3 operate in redundant or independent mode. If a license for PRP was

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
Multilink 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 itself and the
switch is good and that communication is healthy for five minutes, then switching back to port 2 is performed. The
delay in switching back ensures that rebooted switching devices connected to the N60, which signal their ports as
active prior to being completely functional, have time to completely initialize themselves and become active. Once
port 2 is active again, port 3 returns to 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
