Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of highspeed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them, 100BASE-T (Fast Ethernet) provides a nondisruptive, smooth evolution from the current 10BASE-T technology. The non-disruptive and smooth evolution nature, and the dominating potential market base, virtually guarantee cost effective and high performance Fast Ethernet solutions in the years to come. 100Mbps Fast Ethernet is a new standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a straightforward upgrade path and takes advantage of the existing investment in hardware, software, and personnel training. 1 Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol. It transmits packets among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network bandwidth available to users on a local area network. A switch divides a local area network into multiple, separate segments. Each segment has it’s own full Ethernet or Fast Ethernet bandwidth that doesn’t compete with the other segments for network transmission. The switch acts as a high-speed selective bridge between the individual segments. The switch, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another and blocks traffic that does not need to be transmitted. By doing this the total network bandwidth is multiplied, while still maintaining the same network cabling and adapter cards. For Fast Ethernet networks, a switch is an effective way of eliminating the problem of chaining hubs beyond the “tworepeater limit.” A switch can be used to split parts of the network into different collision domains, making it possible to expand a Fast Ethernet network beyond the 205-meter network diameter limit. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are ideal for bridging between existing 10Mbps networks and new 100Mbps networks. 2 Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Today switches are an ideal solution to most kinds of local area network congestion problems. Features The DSS-5+ was designed for easy installation and high performance in an environment where network traffic and the number of users increases continuously. Designed with the small and medium network in mind, the DSS-5+ comes in a small and compact size. Whether used to connect 10Mb and 100Mb network segments and servers together, or to extend an existing switched network, it has the necessary speed to do the job. The DSS-5+ is expandable by cascading two or more switches together. All ports support up to 200Mbps. Any one of its five ports may be used to cascade to an additional switch to open a Full-Duplex Fast Ethernet pipe. The DSS5+ is a perfect choice for sites planning to upgrade to Fast Ethernet in the future. Ethernet workgroups can connect to the DSS-5+ now, and upgraded Fast Ethernet adapters and hubs can be added anytime later without requiring any change to the Switch or network configuration. The Switch combine dynamic memory allocation with storeand-forward switching to ensure that the buffer is effectively allocated for each port, while controlling the data flow between the transmit and receive nodes to guarantee against all possible packet loss. 3 The Switch is an unmanaged 10/100 Fast Ethernet Switch that offers solutions in accelerating small Ethernet workgroup bandwidth. Other key features are: Auto-MDI (media dependent interface) port supports automatic MDI/MDIX crossover detection function gives true ‘plug and play’ capability without the need of confusing crossover cables or crossover ports. Store and forward switching scheme capability. As the result of complete frame checking and error frame filtering, this scheme prevents error packages from transmitting among segments. NWay Auto-negotiation for any port. This allows for auto-sensing of speed (10/100Mbps) thereby providing you with automatic and flexible solutions in your network connections. Flow control for any port. This minimizes dropped packets by sending out collision signals when the port’s receiving buffer is full. Note that flow control is only available in half duplex mode. Data forwarding rate per port is at wire-speed for 100Mbps speed. Data forwarding rate per port is at wire-speed for 10Mbps speed. Data filtering rate eliminates all error packets, runts, etc., per port at wirespeed for 100Mbps speed. Data filtering rate eliminates all error packets, runts, etc., per port at wirespeed for 10Mbps speed. 4 U NPACKING AND S ETUP This chapter provides unpacking and setup information for DSS-5+. Unpacking Open the shipping cartons of the Switch and carefully unpacks its contents. The carton should contain the following items: One DSS-5+ 5-port 10/100Mbps Switch One external power adapter This User’s Guide If any item is found missing or damaged, please contact your local reseller for replacement. Setup The setup of DSS-5+ can be performed using the following steps: The surface must support at least 1.5 Kg for the Switch. The power outlet should be within 1.82 meters (6 feet) of the Switch. Visually inspect the DC power jack and make sure that it is fully secured to the power adapter. Make sure that there is proper heat dissipation from and adequate ventilation around the Switch. Do not place heavy objects on the Switch. 5 I DENTIFYING E XTERNAL C OMPONENTS This section identifies all the major external components of the DSS-5+. Both the front and rear panels are shown followed by a description of each panel feature. The indicator panel is described in detail in the next chapter. Front Panel The figure below shows the front and rear panels of the DSS5+ . DSS-5+ 10/100M Switch LED Indicator Panel Refer to the LED Indicator section for detailed information about each of the hub’s LED indicators. Rear Panel DSS-5+ 10/100M Switch DC Power Jack: Power is supplied through an external AC power adapter. Check the technical specification section for information about the AC power input voltage. Since the switch does not include a power switch, plugging 6 its power adapter into a power outlet will immediately power it on. Auto-MDI Jacks: These jacks supports automatic MDI/MDIX crossover detection function gives true ‘plug and play’ capability without the need of confusing crossover cables or crossover ports. With the Auto-MDI function, you just need to plug-in the network cable to the hub directly and no need to care if the end node is NIC (Network Interface Card) or switches and hubs. LED Indicators Power Indicator (PWR) This LED indicator lights green when the hub is receiving power, otherwise, it is off Link/Act: This indicator light green when the port is connected to a station, if the indicator blinking will be transmitting or received data on the network. 100M: If this indicator light green, mean this port is connected to a 100M Fast Ethernet station. Otherwise, this indicators reminds off, mean this port is connected to a 10M Ethernet station. FDX/COL: This LED indicator light green when a respective port is in full duplex (FDX) mode. Otherwise, it is blinking when collisions are occurring on the respective port 7 C ONNECTING T HE S WITCH This chapter describes how to connect the DSS-5+ to your Fast Ethernet network. PC to Switch A PC can be connected to the Switch via a two-pair Category 3,4, or5 UTP/STP straight-through cable. For 100Mbps operation Category 5 must be used. The PC (equipped with a RJ-45 10Mb Ethernet or 100Mb Fast Ethernet NIC) should be connected to any of the 5 ports (1x - 5x) for the DSS-5+. The LED indicators for PC connection are dependent on the LAN card capabilities. If the LED indicators do not light after making a proper connection, check the PC LAN card, the cable, the Switch conditions and connections. Hub to Switch A hub (10 or 100BASE-TX) can be connected to the Switch via a two-pair Category 3, 4, or 5 UTP/STP straight cable. For 100Mbps operation a Category 5 cable must be used. The connection is accomplished from any port of the hub to any port of the Switch Switch to Switch (other devices) The Switch can be connected to another switch or other devices (routers, bridges, etc.) via a two-pair Category 3, 4, 5 UTP/STP straight or crossover cable. A Category 5 cable must be used for 100Mbps operation. The connection can be done from any (MDI-X) port of the Switch (Switch A) to any of the 10Mbps, 100Mbps (MDI-X) port of the other switch 8 (switch B) or other devices. Port Speed & Duplex Mode After plugging the selected cable to a specific port, the system uses auto-negotiation to determine the transmission mode for any new twisted-pair connection: If the attached device does not support autonegotiation or has auto-negotiation disabled, an autosensing process is initiated to select the speed and set the duplex mode to half-duplex 9 T ECHNICAL S PECIFICATIONS General Standards IEEE 802.3 10Base-T Ethernet IEEE 802.3u 100 Base-TX Fast Ethernet ANSI/IEEE Std 802.3 NWay auto-negotiation IEEE 802.3x Full duplex Flow Control Protocol CSMA/CD Data Transfer Rate Ethernet: 10Mbps (half duplex) 20Mbps (full duplex) Fast Ethernet: 100Mbps (half duplex) 200Mbps (full duplex) Topology Star Network Cables 10BASET: 2-pair UTP Cat. 3,4,5 (100 m), EIA/TIA568 100-ohm STP 100BASE-TX: 2-pair UTP Cat. 5 (100 m), EIA/TIA568 100-ohm STP Number of Ports 5 x 10/100Mbps NWay Auto-MDI ports 10 Physical and Environmental DC inputs 7.5VDC/1A Power Consumption 7.5 watts.
