2. To determine that the power supply and module are operating properly,
check the power supply and Module Status indicators and alphanumeric
display.
The alphanumeric display cycles through the following states: TEST PASS - OK - REV x.x, where x.x is the firmware revision of the module.
The display then alternates between OK and port link status for both
ports.
This graphic shows the front of the module for these modules (extendedtemperature versions [catalog numbers 1756-EN2TXT and 1756EN2TRXT] not shown).

Install or Remove the Module Under Power (RIUP)
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 electric arc can occur. An electric arc can cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electrical arcs can cause excessive wear to contacts on both the module
and its mating connector. Worn contacts can create electrical resistance that can
affect module operation.
ATT EN TI ON : Although the module is designed to support RIUP, when you
remove or insert the module with field-side power applied, unintended
machine motion or loss of process control can occur. Exercise extreme caution
when using this feature.
Follow these steps to remove or replace the module.
1. Push the upper and lower module tabs to disengage them.
2. Slide the module out of the chassis.
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 and assign the same network configuration.

ATTENTION: Environment and Enclosure
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 not intended for use in residential environments and may not provide adequate protection to radio communication
services in such environments.
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 or be approved for the application 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.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1
• NEMA 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided by enclosures
, for additional installation requirements
