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

European Hazardous Location Approval
WARNING: This equipment is intended for use in potentially
explosive atmospheres as defined by European Union Directive
94/9/EC and has been found to comply with the Essential Health
and Safety Requirements relating to the design and construction
of Category 3 equipment intended for use in Zone 2 potentially
explosive atmospheres, given in Annex II to this Directive.
Compliance with the Essential Health and Safety Requirements has
been assured by compliance with EN 60079-15 and EN 60079-0.
WARNING:
• This equipment is not resistant to sunlight or other sources of UV
radiation.
• This equipment must be installed in an enclosure providing at
least IP54 protection when applied in Zone 2 environments.
• This equipment shall be used within its specified ratings defined
by Rockwell Automation.
• Provision shall be made to prevent the rated voltage from being
exceeded by transient disturbances of more than 40% when
applied in Zone 2 environments.
• Secure any external connections that mate to this equipment by
using screws, sliding latches, threaded connectors, or other
means provided with this product.
• Do not disconnect equipment unless power has been removed or
the area is 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.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines,
Rockwell Automation publication 1770-4.1
installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for
explanations of the degrees of protection provided by different
types of enclosure.

Prevent Electrostatic Discharge
ATTENTION: This equipment is sensitive to electrostatic
discharge, which can cause internal damage and affect normal
operation. Follow these guidelines when you handle this
equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when
not in use.
About the Stratix 2000 Ethernet Unmanaged Switches
The Ethernet unmanaged switches can be used to divide an Ethernet network
into segments, and to direct network traffic more efficiently than using repeating
hubs. This allows for a larger network size, regardless of the amount of network
traffic.
Connecting one of the switches’ ports to a single device segments the network,
letting you dedicate bandwidth to that device. Unmanaged switches also enable
multiple simultaneous communication between devices on different ports.

IMPORTANT
.
The switches are available in the following port configurations for attaching
local devices.
Cat. No. Port Configuration
1783-US03T01F 3-port copper
1783-US05T 5-port copper
1783-US06T01F 6-port copper
1783-US08T 8-port copper
1-port fiber
1-port fiber
The 3-port copper 1-port fiber switch (catalog number 1783-US03T01F) is
shown in this publication.
The individual ports autonegotiate link speeds (10 Mbps or 100 Mbps). To
improve data throughput, traffic is restricted to ports in a data exchange, while
other data is simultaneously exchanged on other ports.
The device you connect to a switch should have its Ethernet port
configured for autonegotiate to avoid confusion between halfand full-duplex communication. You can also set the device’s
Ethernet port to half-duplex. Failure to do so may result in higher
error rates.
Rockwell Automation Publication 1783-IN001D-EN-P - January 2011

In addition to a power status indicator, each port has these indicators.
• Each copper port has two link/status/activity indicators (only one of
which is active at a time).
• The fiber optic port has one link/status/activity indicator.
When this indicator is lit Link speed is
Amber (copper port only) 10 Mbps
Green 100 Mbps
The switches operate on low-voltage AC or DC power.
Features supported by the Ethernet unmanaged switches include the following:
• 10 Mbps or 100 Mbps, full- or half-duplex communication, per copper
port autonegotiation
• Automatic crossover detection (auto MDIX)
• LC-type fiber optic connector; multimode cable
Use Caution When Handling Switches with Fiber Optic Ports
Observe the following when using the unmanaged switches equipped with fiber
optic ports (catalog numbers 1783-US03T01F and 1783-US06T01F).
ATTENTION: Do not look into the optical port. Under certain
conditions, viewing the optical port may expose the eye to
hazards. When viewed under some conditions, the optical port
may expose the eye beyond the maximum permissible exposure
recommendations.
