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,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, for additional
installation requirements
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the degrees of
protection provided by 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.

Stratix 2000 Ethernet Unmanaged Switch 5
About the Switch
The Stratix 2000 Ethernet unmanaged switch 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 switch 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.
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.
IMPORTANT
Features supported by the Ethernet unmanaged switches include the following:
The device you connect to a switch must have its Ethernet port configured for autonegotiate to
avoid confusion between half- and 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.
• 10 Mbps or 100 Mbps, full- or half-duplex communication, per copper port
autonegotiation
• Automatic crossover detection (auto MDIX)
Before You Begin
Observe these guidelines before installing the switch:
• For 10/100 ports, the cable length from a switch to an attached device cannot
exceed 100 m (328 ft).
• Clearance to front and rear panels must meet these conditions:
– Front-panel status indicators can be easily read.
– Access to ports is sufficient for unrestricted cabling.
– DC (or AC) power connectors are within reach of the connection to their power
source.
Rockwell Automation Publication 1783-IN010A-EN-P - June 2013
6 Stratix 2000 Ethernet Unmanaged Switch
• To prevent the switch from overheating, observe the following minimum
clearances:
– Top and bottom: 50.80 mm (2 in.)
– Sides: 50.80 mm (2 in.)
– Front: 63.50 mm (2.50 in.)
• Temperature surrounding the unit must not exceed 140 °F (60 °C).
Install the Switch
Perform these procedures to install the switch:
• Install the Switch on a DIN Rail on page 6
• Remove the Switch from a DIN Rail on page 8
• Wire the Switch on page 8
• Connect the Power Supply on page 10
• Ground the Switch on page 12
• Apply Power to the Switch on page 13
Install the Switch on a DIN Rail
ATTENTION: When using DIN rail mounting, additional grounding is also accomplished through
the DIN rail to chassis ground. Use zinc-plated yellow-chromate steel DIN rail to assist in proper
grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode,
oxidize, or are poor conductors, can impede proper grounding. Secure DIN rail to mounting surface
approximately every 200 mm (7.8 in.).
Follow these procedures to install the switch on a DIN rail.

2. Position the switch so that the top of the DIN rail mounting clip is slightly above
the upper DIN rail edge.
3. With the bottom of the switch angled away from the panel, slide the switch
downward until the mounting clip spring is behind the top edge of the DIN rail.
4. Press the switch downward to compress the spring.
5. Press the bottom of the switch toward the panel until the clip locks into place over
the bottom edge of the DIN rail.

Remove the Switch from a DIN Rail
1. Gently push the switch downward to compress the mounting clip spring.
2. Rotate the bottom of the switch away from the DIN rail until the bottom of the
mounting clip is clear of the lower rail.
3. Lift the switch up until the mounting clip and springs clear the upper DIN rail.
Wire the Switch
For simplified cabling, the switch supports automatic medium-dependent interface
crossover (auto-MDIX). With auto-MDIX, the switch detects the required cable type for
copper Ethernet connections and configures the interfaces accordingly. You can use either
crossover or straight-through cables for connections to the switch's 10/100 Ethernet ports,
regardless of the type of device on the other end of the connection.
Use either straight-through or crossover style, twisted four-pair, Category 5e or better
cables with RJ45 connectors to connect to the switch's Ethernet ports.

WARNING: Before performing any of the following procedures, make sure power is removed from
the DC circuit or the area is nonhazardous before proceeding.
ATTENTION: To comply with the CE Low Voltage Directive (LVD), this equipment must be powered
from a source compliant with the safety extra low voltage (SELV) or protected extra low voltage
(PELV). To comply with UL restrictions, this equipment must be powered from a source compliant
with Class 2 or Limited Voltage/Current.
Keep the following in mind when connecting the power supply to the switch:
• Use the supplied 3-pole, 5.08 mm (0.20 in.) pitch terminal block to connect the
power wire.
• Use wires of 2.5 …
• Grounding resistance must be <2.5 .

ATTENTION: This product is intended to be mounted to a well-grounded mounting surface, such a
metal panel. For safety and maximum noise immunity, the switch must be grounded by using the
Protective Ground (PE) grounding screw on the housing. Functional Earth ground (FE) is internally
connected to the PE ground. It may be used to ground the DC power supply, for example. The PE
chassis ground must be connected to a reliable earth ground at all times.
• Grounding resistance for PE must be less than 2.5 .
• For proper grounding, use a suitable ring terminal for the chassis PE ground screw,
and minimum 2.5 mm
(14 AWG) wire.
• Torque must not exceed 1.82 Nm (16.10 lbin).
