Important User Information

Solid-state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.rockwellautomation.com/literature/) describes some important differences between solid-state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid-state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual.

Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc., is prohibited.

Throughout this manual, when necessary, we use notes to make you aware of safety considerations.

WARNING: Identifies information about practices or circumstances that can cause an explosion in a hazardous environment, which may lead to personal injury or death, property damage, or economic loss.

ATTENTION: Identifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss. Attentions help you identify a hazard, avoid a hazard and recognize the consequences.

SHOCK HAZARD: Labels may be on or inside the equipment, for example, a drive or motor, to alert people that dangerous voltage may be present.

BURN HAZARD: Labels may be on or inside the equipment, for example, a drive or motor, to alert people that surfaces may reach dangerous temperatures.

4 Stratix 2000 Ethernet Unmanaged Switch

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 The device you connect to a switch must 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.

Features supported by the Ethernet unmanaged switches include the following:

•10 Mbps or 100 Mbps, fullor 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.
