Set the Network Address
The adapter ships with the thumbwheel switches set to
999 and DHCP enabled. You can set the network
Internet Protocol (IP) address in these ways:
• Use the thumbwheel switches on the module.
• Use a Dynamic Host Configuration Protocol
(DHCP) server, such as Rockwell Automation
BootP/DHCP.
• Retrieve the IP address (if previously set) from
nonvolatile memory.
The adapter reads the thumbwheel switches first to
determine if the switches are set to a valid number. You
set the node address by using the three-position
thumbwheel switch. Press the + or - buttons to change
the number. Valid settings are 001…254.
When the switches are set to a valid number, the adapter’s
IP address is 192.168.1.xxx (where xxx represents the
number set on the switches). The adapter’s subnet mask
is 255.255.255.0 and the gateway address is set to 0.0.0.0.
The adapter does not have a host name assigned, or use
any Domain Name System when using the thumbwheel
settings.
Network Address Thumbwheel
If you set the switches to an invalid number (such as 000,
or a value greater than 254), the adapter checks to see if
you enabled DHCP.
The switch value of 888 lets you reset all configuration
parameters to the factory settings. This is useful in
situations where you want to reuse a module that has an
unknown configuration.
Refer to the EtherNet/IP Adapter User Manual,
publication ENET-UM001, for more information.
Indicators
The faceplate of the 1794-AENT adapter is provided
with three bicolor indicators.

DHCP Enabled and Not Enabled
If DHCP is Then the adapter
Enabled Asks for an address from a DHCP server. The
DHCP server also assigns other Transport Control

Not enabled Uses the IP address (along with other TCP
configurable parameters) stored in nonvolatile
memory.
