Installing the DHR21B/41B option
Assembly and Installation Notes
LED Link / Activity The two LEDs Link (green) and Activity (yellow) integrated in the RJ45 plug
connectors (X30-1, X30-2) display the state of the Ethernet connection.
4.9.9 Setting IP address parameters
Initial startup If the EtherNet/IP and MODBUS TCP protocol is set using the DIP switch, the default
protocol for the DHR21B/41B option will be "DHCP" (Dynamic Host Configuration
Protocol). This means that the option expects its IP address parameters from a DHCP
server.
Once the DHCP server has been configured and the settings have been made for the
subnet mask and the standard gateway, the DHR21B/41B option must be inserted in the
assignment list of the DHCP server. In doing so, the MAC ID of the DHR21B/41B option
is allocated a valid IP address.

INFORMATION
• DHCP remains disabled when you reset the DIP switch "2
0
" to "0" (= left = OFF).
You can re-activate DHCP via the EtherNet/IP TCP/IP interface object, parameter
P785 or the DHCP server by Rockwell Automation.
• DHCP remains active when resetting the values to the default setting (P802
Factory setting).
INFORMATION
There is a free DHCP server available on the Rockwell Automation homepage. The
tool is known as "BOOTP Utility" and can be downloaded from the following website:
INFORMATION
The configured IP address parameters are adopted permanently by the parameter set
when DHCP is deactivated after the IP address has been assigned.
