Introduction Introduction This manual will help you install and maintain the Etherswitch Industrial Ethernet Switch This product is extremely easy to install and operate because little or no user configuration is required. Once the Ethernet connections are made and the unit is powered up it will immediately begin to operate. Operation Unlike an Ethernet hub that broadcasts all messages out all ports, the Etherswitch Industrial Ethernet Switch will intelligently route Ethernet messages only out the appropriate port. The major benefits of this are increased bandwidth and speed, reduction or elimination of message collisions, and deterministic performance when tied with real-time systems. The Etherswitch Industrial Ethernet Switch supports both 10BaseT (10 Mbps) and 100BaseTx (100 Mbps) via RJ45 ports. Each of these ports will independently auto-sense the speed, allowing you to interface to regular or fast Ethernet devices. Performance Specifications The following are general specifications. Refer to Technical Specifications Section for complete technical specifications.

Part Number: 4510 Power LED This LED will be on continuously when proper power has been applied to the unit. ACT / LNK LEDs The activity (ACT) and link (LNK) indication is combined into one LED (labeled “ACT/LNK” or “A”) on the Etherswitch Industrial Ethernet Switch. There is one of these LEDs per port. OFF – This would indicate that there is not a proper Ethernet connection (Link) between the port and another Ethernet device. Make sure the proper cable type is in use and that it has been plugged securely into the ports at both ends. See section 5 for proper Ethernet cabling. ON Solid (not flashing) – This would indicate that there is a proper Ethernet connection (Link) between the port and another Ethernet device, but no communications activity is detected. Flashing - This would indicate that there is a proper Ethernet connection (Link) between the port and another Ethernet device, and that there is communications activity. 10 / 100 LEDs This LED indicates what speed of communications is detected on the port. OFF – A 10 Mbps (10BaseT) connection is detected. ON – A 100 Mbps (100BaseTx) connection is detected. Sealevel Systems Etherswitch Page 3 Installation Installation Overview The Etherswitch can be snapped onto a standard DIN rail (EN50022) or screwed directly to a flat panel. Refer to the mechanical drawing below. Sealevel Systems Etherswitch Page 4 Power Wiring Power Wiring Overview The Etherswitch can be powered from the same DC source that is used to power your I/O devices. 10 to 30 VDC needs to be applied to terminals 2 and 3. Refer to the wiring diagram below. Terminal 1 should be tied to panel or chassis ground. Sealevel Systems Etherswitch Page 5 Ethernet Wiring Ethernet Wiring Overview The Etherswitch 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 Ethernet ports are then connected to 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 Ethernet wiring practices when installing the Etherswitch Industrial Ethernet Switch. Typical Etherswitch Industrial Ethernet Switch Sealevel Systems Etherswitch Page 6 Switching Installation Switch Installation RJ45 Wiring Guidelines 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 are available as straight-thru or crossover configurations. The following is a guide for when to use each type: UPLINK (MDI) STANDARD (MDI-X) Cable Type Cable Type Port connected to to Use Port connected to 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 Straight-thru Other Ethernet enabled Cross-over devices devices Uplink port on another Straight-thru) Standard port on another Straight-thru switch or hub switch or hub Straight-thru Cable Wiring Cross-over Cable Wiring Pin 1 Pin 1 Pin 1 Pin 3 Pin 2 Pin 2 Pin 2 Pin 6 Pin 3 Pin 3 Pin 3 Pin 1 Pin 6 Pin 6 Pin 6 Pin 2 Ethernet Connector Pin Positions Pin # MDI-X MDI Port Auto-MDI/ Ethernet Port (typical for MDI-X Device Port Ethernet uplink) Connector 1 TX+ RX+ TX/RX+ RX+ 2 TX- RX- TX/RX- RX- Pinouts 3 RX+ TX+ RX/TX+ TX+ 6 RX- TX- RX/TX- TX- Cable Distance The maximum cable length for 10/100BaseT(x) is typically 100 meters (328 ft.). From To Maximum Distance Switch Switch or Hub 100 meters (328 feet) Switch or Hub PLC, Ethernet I/O, PC, etc. 100 meters (328 feet) Note: Hubs and Switches are different devices. Hubs simply broadcast all messages out all ports. Switches intelligently route messages only out the appropriate port Sealevel Systems Etherswitch Page 7 Switching Features Switching Features Overview Here’s a brief explanation of the features found in the Etherswitch Industrial Ethernet Switch documented by this manual. 10BaseT and 100BaseTx Auto-detection Standard Ethernet (10BaseT) has a maximum speed of 10 Mbps in half duplex mode. Fast Ethernet (100BaseTx) has a maximum speed of 200 Mbps in full duplex mode. The RJ45 ports on the Etherswitch Industrial Ethernet Switch automatically select the appropriate speed. 1.4 Gbps combined bandwidth With full duplex and 100BaseTX each port can provide a full 200 Mbps of data throughput. 1K MAC addresses with automatic 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 or auto-negotiating speed The RJ45 ports of the Etherswitch Industrial Ethernet Switch will auto-negotiate with the connected device to determine the optimal speed (10 Mbps vs. 100 Mbps). 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 Etherswitch Industrial Ethernet Switch will drop a packet after 16 collisions. Back pressure for half-duplex The Etherswitch Industrial Ethernet Switch will apply “back pressure” when necessary with half-duplex operation. This “back pressure” will reduce congestion on busy networks. Broadcast storm protection Broadcasts and multicasts are limited to 25% of the available bandwidth. Buffering SRAM is used for buffering the messages. The Etherswitch Industrial Ethernet Switch features 128KB (32Kx32) of SRAM, with 1024 buffers (205 per port). Each buffer is 128 bytes. Unmanaged operation The Etherswitch Industrial Ethernet Switch requires no supervisory processor to operate properly. Flow control The Etherswitch Industrial Ethernet Switch automatically supports flow control frames on both receive and transmit sides. Sealevel Systems Etherswitch Page 8 Switching Features Forwarding The Etherswitch 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 Etherswitch will not forward error packets, 802.3x pause frames, or “local” packets. Full/Half duplex operation The RJ45 ports of the Etherswitch Industrial Ethernet Switch support both full and half duplex flow control. The fiber optic port(s) has a settable jumper or switch, which allows you to select the desired operation. Illegal frames Illegal frames as defined by IEEE 802.3 will be dropped. This includes short frames, long frames, and FCS error frames. IEEE 802.3 compliant The Etherswitch Industrial Ethernet Switch strictly abides to the IEEE 802.3 standard for 10BaseT and 100BaseTX Ethernet communications. Late collision If a packet experiences collisions after 512 bit times of transmission, the packet will be dropped. Latency The typical latency of a message is 5 microseconds or faster. The latency is the time it takes a message to be routed internal to a switch from one port to another. Plug and play This means that most functions or features of the Etherswitch Industrial Ethernet Switch are automatic and that there are minimal or 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 Etherswitch 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.
