The challenge in achieving these benefits on the factory floor is designing a network that will stand up to conditions much harsher than the office environment for which most Ethernet components were designed. The RJ-Lnxx line of Industrial Ethernet Connectivity Products from Woodhead Connectivity offers a variety of infrastructure products designed to perform reliably in demanding manufacturing, processing and commercial applications. The ENHSD, available in 5 or 9 port versions, is intended to mount on a DIN rail and survive the temperature and vibration extremes that may be found in practice within a standard industrial enclosure. While this manual explains the basic functionality of the unit, no programming is required to get the unit up and running. The ENHSD should function upon making the power and network connection as described within. Should you encounter a problem with operation of your switch, please contract Technical support at WOODHEAD CONNECTIVITY 3411 Woodhead Dr. Northbrook, IL (847) FAX (847)

4 Section 1 Overview Operation General Information This manual will help you install and maintain the RJ-Lnxx Industrial Ethernet Switch. This unmanaged switch is extremely easy to install and operate because no user configuration is required. Once the Ethernet connections are made and the unit is powered up it will immediately begin to operate. The vast majority of Ethernet networks are configured in a star topology, requiring Hub devices to direct messages between the stations on the network. While this can be accomplished with a Repeater Hub which receives a message then broadcasts it all ports, this an inefficient use of bandwidth. Additionally, all stations connected via a Repeater Hub share a collision domain, meaning only one station can transmit at any one time. The ENHSD is an active switch, which unlike a Repeater Hub will intelligently route Ethernet messages only out the appropriate port. This switch is also a store and forward device, enabling multiple stations to communicate with the switch simultaneously. In factory automation environments, this function is essential for transmission of time critical information in a deterministic fashion. The RJ-Lnxx Industrial Ethernet Switch supports both 10BaseT (10 Mbps) and 100BaseTx (100 Mbps). Each port will independently auto-sense the speed allowing you to interface to regular or fast Ethernet devices.

8 Section 5 Overview Ethernet Wiring The RJ-Lnxx Industrial Ethernet Switch provides connections to Ethernet devices on the factory floor. Typically the uplink port is used to connect to another Ethernet switch or hub that is connected to the main Ethernet backbone. The other four Ethernet ports are then connected to the Ethernet devices such as PLCs, Ethernet I/O, or industrial computers. Electrical isolation is provided on the Ethernet ports for increased reliability. Please follow normal 10/100BaseT(x) Ethernet wiring practices when installing the RJ-Lnxx Industrial Ethernet Switch. Typical RJ-Lnxx Industrial Ethernet Switch Installation Ethernet Wiring Guidelines Ethernet Cable Type Use data-quality (not voice-quality) twisted pair cable rated category 5 with standard RJ45 connectors. For best performance use shielded cable. Please note that these cables can be wired as straight-thru or cross-over. The following is a guide to when to use each type: RJ-Lnxx Industrial Ethernet Switch STANDARD Port to RJ-Lnxx Industrial Ethernet Switch UPLINK Port to Cable Type to Use Cable Type to Use PC card Straight-thru PC card Cross-over Ethernet I/O Straight-thru Ethernet I/O Cross-over PLC Straight-thru PLC Cross-over Other Ethernet enabled devices Uplink port on another switch or hub Straight-thru Straight-thru (see note) Other Ethernet enabled devices Standard port on another switch or hub Cross-over Straightthru Note: Some Ethernet switches and hubs have a settable switch on their Uplink port that will change how the port is internally wired. Make sure this switch is set in the To Hub/Switch (MDI) position as opposed to the To PC (MDI-X) position. RJ-Lnxx Industrial Ethernet Switch User Manual Page 8

The fiber optic port on the switch is comprised of a pair of SC connectors, which are labeled with RX and TX. When making your fiber optic connections, make sure that the transmit (TX) port of the switch connects to the receive (RX) port of the other device, and the receive (RX) port of the switch connects to the transmit (TX) port of the other device. The ACT/LNK LED will be ON solid when you have made a proper connection. The RJ45 ports will auto-sense for Full or Half-duplex operation. No user configuration is necessary. The fiber optic port has a movable slide-switch that allows you to select either Full or Half-duplex operation. This slide-switch is located next to the fiber optic connector. See diagram. Note: You must cycle power to the switch after changing the slide-switch position. Top View of ENHSDURS5 Full Duplex Half Duplex RJ-Lnxx Industrial Ethernet Switch User Manual Page 9 of 13

10 Section 6 Switching Features Switching Features Here s a brief explanation of the features found in the RJ-Lnxx Industrial Ethernet Switch. 10BaseT and 100BaseTx Standard Ethernet (10BaseT) has a maximum speed of 10 Mbps (megabits per second). Fast Ethernet (100BaseTx) has a maximum speed of 100 Mbps. The RJ-Lnxx Industrial Ethernet Switch automatically supports both types. 100BaseFX (multi-mode) fiber optic port The fiber optic port found on some models is classified as 100BaseFX and supports 100 Mbps operation only.. Multimode Fiber allows for multiple wavelengths over a cable with a core diameter of typically 50 or 62.5 microns. The maximum distance for multimode is 2 km. Single-mode models, which are available by special order, use a single wavelength and cable core diameter of around 10 microns which allows for a maximum distance of 15 km or more. 1.4 Gbps (5 port)/ 2.0 Gbps combined bandwidth With full duplex and 100BaseTx communications, each port can provide a full 200 Mbps of data throughput. 1K MAC addresses with automatic address learning, aging and migration Each Ethernet device inserts its unique MAC address into each message it sends out. The port on the switch used for a given MAC address is automatically learned when a frame is received from that address. Once an address is learned, the switch will route messages to only the appropriate port, instead of broadcasting messages out all ports like a hub. A time stamp is also placed in memory when a new address is learned. This time stamp is used with the aging feature, which will remove unused MAC addresses from the table after 300 seconds. If a device moves, the associated port on the switch will be changed (migrated) as needed. Up to 1,024 MAC addresses can be stored and monitored at any time. Auto-sensing speed and flow control The RJ-Lnxx Industrial Ethernet Switch will auto-negotiate with the connected device to determine the optimal speed (10 Mbps vs. 100 Mbps) and flow control for each port. Automatic power saving If there is no cable on a port most of the circuitry for that port is disabled to save power. Backoff operation The RJ-Lnxx Industrial Ethernet Switch will drop a packet after 16 collisions. Back pressure for half-duplex The RJ-Lnxx Industrial Ethernet Switch will apply back pressure which will inhibit stations from transmitting for 20 ms, when necessary with half-duplex operation. This back pressure will enable the switch to clear its buffer and reduce congestion on busy networks. Broadcast storm protection Broadcasts and multicasts are limited to 25% (5 port) or 5% (9 port) of the available bandwidth. Buffering SRAM is used for buffering the messages. There are 1024 (128 bytes each) buffers RJ-Lnxx Industrial Ethernet Switch User Manual Page 10

11 available. Each port is allocated 205 buffers. Unmanaged operation The RJ-Lnxx Industrial Ethernet Switch requires no supervisory processor to operate properly. Flow control The RJ-Lnxx Industrial Ethernet Switch automatically supports flow control frames on both the transmit and receive sides. Forwarding The RJ-Lnxx Industrial Ethernet Switch supports store and forward mode. It will forward messages with known addresses out only the appropriate port. Messages with unknown addresses, broadcast messages, and multicast messages will get forwarded out all ports except the source port. The RJ-Lnxx Industrial Ethernet Switch will not forward error packets, 802.3x pause frames, or local packets. Full/Half duplex operation The RJ-Lnxx Industrial Ethernet Switch automatically supports (auto-senses) both full and half duplex flow control. Illegal frames Illegal frames as defined by IEEE will be dropped. This includes short frames, long frames, and FCS error frames. IEEE compliant The RJ-Lnxx Industrial Ethernet Switch strictly abides to the IEEE standard for 10BaseT and 100BaseTx Ethernet communications. Late collision If a packet experiences collisions after 512 bit times of transmission then the packet will be dropped. Plug and play This means that every function or feature of the RJ-Lnxx Industrial Ethernet Switch is automatic and that there are no optional parameters that need to be set. Just plug in your Ethernet cables, apply power, and the unit will immediately begin to operate. Protocol independent The RJ-Lnxx Industrial Ethernet Switch will work with all popular Ethernet protocols and networks such as TCP/IP, the Internet (IP), UDP, NetBEUI, and many more. It is compatible with all protocols that run over standard Ethernet (IEEE 802.3). In fact, it will support packets of different protocols simultaneously.
