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.

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.
Rockwell Automation Publication 1783-IN001D-EN-P - January 2011
Stratix 2000 Ethernet Unmanaged Switches 7
IMPORTANT
.
The switches are available in the following port configurations for attaching
local devices.
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
8 Stratix 2000 Ethernet Unmanaged Switches
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 litLink speed is
Amber (copper port only)10 Mbps
Green100 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.

Install the Switch
Follow these procedures to install the switch.
WARNING: An electrical arc can occur:
• if you connect or disconnect the communication cable with
power applied to this module or any device on the network.
• if you connect or disconnect wiring while the field-side power is
on
This can cause an explosion in hazardous location installations. Be
sure that power is removed or the area is nonhazardous before
proceeding.
Mount the Switch
Mount the switch vertically on a horizontal DIN rail, either free-standing or at
the rear of the control cabinet. You can mount the switch adjacent to another
Stratix 2000 switch.
ATTENTION: Failure to mount the switches vertically on a
horizontal DIN rail may result in overheating and switch failure.

Make sure that the switch is oriented so that the ports face forward. The Power
status indicator should be oriented to the right. See the illustrations on page 12.
ATTENTION: Maintain 50 mm (2 in.) of space on the right and left
sides, and the top and bottom of the switch from enclosure walls,
wireways, and adjacent equipment, for ventilation and electrical
isolation.
.Follow these steps to mount the switch on a DIN rail.
1. Use the 6 mm (0.25 in.) screwdriver to open the latch at either the top or
bottom of the switch.
2. Hold the latch open and hook the latch over the DIN rail.
3. Remove the screwdriver and allow the latch to close.

Grounding Considerations
ATTENTION: For proper grounding, you must always connect the
power supply functional-ground screw when connecting the
power supply. You must provide an acceptable grounding path for
each device in your application. For more information on proper
grounding guidelines, refer to Industrial Automation Wiring and
Grounding Guidelines, publication 1770-4.1
This product is intended to be mounted to a well-grounded mounting surface,
such as a metal panel. The functional-earth ground connection to the product is
through the specified pin on the AC and DC connection terminals.
Only one of these ground connections is required.
• Pin 1 on the DC connection terminals
• Pin 4 on the AC connection terminals
Connect the functional earth (FE) ground to the ground pin of either the DC
(pin 1) or AC (pin 4) power connector on one of the connectors at the top and
bottom of the switch.
