Chapter 3 Configure the Adapter for Your EtherNet/IP Network
• Studio 5000 Logix Designer application
• RSLinx software
If the adapter is not in Implicit Protected Mode, the adapter does not reject attempts to perform the
tasks that are described previously.
For example, after the adapter is initially powered up, but no I/O connections are established yet,
the adapter is not in Implicit Protected Mode. Additionally, if the adapter is not in Implicit Protected
Mode then you can attempt to update the adapter firmware revision and the adapter does not
reject the attempt.
Enable orDisable Web Server
and SNMP Agent
You can enable or disable the web server as an added security feature from firmware revision 2.011
or later. You can enable or disable the SNMP agent using the AOP revision 25.06.26.0 or later.
Both the web server and the SNMP agent are enabled by default from firmware revision 2.011 or
later.
Disabling the web server in conjunction with using the Implicit Protected Mode decreases the
possibility of a security breach.
For more information on how to enable or disable the web server, see Enable or Disable the Web
Server on page 45.
If the adapter enters Implicit Protected Mode each time the adapter powers up, check
application controllers to determine if there are active I/O connections that are opened
via the adapter.
