North American Hazardous Location Approval
The following information applies
when operating this equipment in
hazardous locations.
Products marked “CL I, DIV 2, GP A, B, C, D” are
suitable for use in Class I Division 2 Groups A, B, C,
D, Hazardous Locations and nonhazardous
locations only. Each product is supplied with
markings on the rating nameplate indicating the
hazardous location temperature code. When
combining products within a system, the most
adverse temperature code (lowest “T” number)
may be used to help determine the overall
temperature code of the system. Combinations of
equipment in your system are subject to
investigation by the local Authority Having
Jurisdiction at the time of installation.
WARNING:
Explosion Hazard -
•Do not disconnect equipment
unless power has been removed
or the area is known to be
nonhazardous.
•Do not disconnect connections to
this equipment unless power has
been removed or the area is
known to be nonhazardous.
Secure any external connections
that mate to this equipment by
using screws, sliding latches,
threaded connectors, or other
means provided with this product.
•Substitution of components may
impair suitability for Class I,
Division 2.
•If this product contains batteries,
they must only be changed in an
area known to be nonhazardous.

Environment and Enclosure
ATTENTION: This equipment is intended for use in a Pollution
Degree 2 industrial environment, in overvoltage Category II
applications (as defined in IEC 60664-1), at altitudes up to 2000 m
(6562 ft) without derating.
This equipment is considered Group 1, Class A industrial
equipment according to IEC/CISPR 11. Without appropriate
precautions, there may be difficulties with electromagnetic
compatibility in residential and other environments due to
conducted and radiated disturbances.
This equipment is supplied as open-type equipment. It must be
mounted within an enclosure that is suitably designed for those
specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from
accessibility to live parts. The enclosure must have suitable
flame-retardant properties to prevent or minimize the spread of
flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or
equivalent) if non-metallic. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent sections of this
publication may contain additional information regarding specific
enclosure type ratings that are required to comply with certain
product safety certifications.

Determine Module Slot Location
Install the module in any slot in the ControlLogix chassis. You can install
multiple 1756-EN2T modules in the same chassis. The following figure shows

ControlLogix EtherNet/IP Module 9
Set the Network Address
The module ships with the rotary switches set to 999 and BOOTP enabled. You
can set the network Internet Protocol (IP) address three ways.
• Use the rotary switches on the top of the module.
• Use a BOOTP server or Dynamic Host Configuration Protocol
(DHCP) server, such as Rockwell Automation BOOTP/DHCP.
• Use the Rockwell Automation RSLinx or RSLogix 5000 software.

The module reads the rotary switches first to determine if they are set to a valid
number for the last portion of the IP address. Valid numbers range from
001…254. When the switches are set to a valid number, the module’s IP address
is 192.168.1.xxx (where xxx represents the number set on the switches). The
module’s subnet mask is 255.255.255.0 and the gateway address is set to 0.0.0.0.
The module does not have a host name assigned, or use any Domain Name
System when using the rotary switch settings.
Rockwell Automation Publication 1756-IN603C-EN-P - April 2010
10 ControlLogix EtherNet/IP Module
To reset the module to its initial out-of-the-box settings, reset the switches to
888 and cycle power.
IMPORTANT
Do not use the 888 switch setting during normal module operation.
After cycling power with the switches set to 888, remove the module and set the
switches to their final value. When you set the rotary switches to a value other
than 888, or to the valid IP address values 001…254, the software configuration
determines the IP address.

Make sure that the module backplane connector properly connects to
the chassis backplane.
TIP
The module is properly installed when it is flush with the power supply or
other installed modules.
Connect the Module to the EtherNet/IP Network
WARNING: If you connect or disconnect the communication cable
with power applied to this module or any device on the network,
an electrical arc can occur. This could cause an explosion in
hazardous location installations.
1. Be sure that power is removed or the area is nonhazardous before
proceeding.
2. Attach the RJ45 connector to the Ethernet port on the bottom of the
module as shown.

14 ControlLogix EtherNet/IP Module
Program the Module via the USB Port
WARNING: The USB port is intended for temporary local
programming purposes only and is not intended for permanent
connection. If you connect or disconnect the USB cable with power
applied to this module or any device on the USB network, an
electrical arc can occur. This could cause an explosion in
hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding.
A Samtec Inc. RSP-119350 USB cable is required to maintain
hazardous location certifications.
Be sure that power is removed or the area is nonhazardous before proceeding.
The module has a USB device port that uses a series B receptacle. To use the USB
port, you must have RSLinx software, version 2.51 or later installed on your
computer. Use a USB cable to connect your computer to the USB port. The
connection lets you download programs to controllers and to configure Ethernet
modules directly from your computer.
ATTENTION:
• The USB port is designed for a temporary connection only.
• The USB cable is not to exceed 3.0 m (9.84 ft) and must not
contain hubs.
• To maintain product certification integrity, you must use SAMTEC
cable, part number RSP-119350.

• PA SS
• OK
• REV x.x
where x.x is the module’s firmware revision.
The display then alternates between OK and the module’s EtherNet/IP address.
Install or Remove the Module Under Power
You can install or remove this module while chassis power is applied.
WARNING: When you insert or remove the module while
backplane power is on, an electrical arc can occur. This could
cause an explosion in hazardous location installations. Be sure
that power is removed or the area is nonhazardous before
proceeding. Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating connector. Worn
contacts may create electrical resistance that can affect module
operation.
1. Push on upper and lower module tabs to disengage them.

2. Slide the module out of the chassis.
IMPORTANT
Rockwell Automation Publication 1756-IN603C-EN-P - April 2010
If you want to replace an existing module with an identical one, and you
want to resume identical system operation, you must install the new
module in the same slot.
