The D-Link GO-SW-5E is a 5-port Fast Ethernet Easy Desktop Switch, designed to integrate 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities into a single, high-performance, and user-friendly solution. This device is particularly suited for small workgroups, Small to Medium Businesses (SMBs), and any network that experiences bandwidth-intensive applications.
The GO-SW-5E leverages Fast Ethernet technology, which operates at ten times the speed of traditional Ethernet, thereby offering enhanced performance for existing Ethernet-based networks. It adheres to the IEEE 802.3 LAN committee standard for 100Mbps Fast Ethernet, an extension of the 10Mbps Ethernet standard. This allows it to transmit and receive data at 100Mbps while maintaining the CSMA/CD Ethernet protocol. Its compatibility with all 10Mbps Ethernet environments ensures a straightforward upgrade path, allowing users to capitalize on their existing investments in hardware, software, and personnel training.
A key feature of the GO-SW-5E is its incorporation of D-Link's Green Technology. This technology implements special power-saving features that dynamically adjust power usage based on link status, especially at 100Mbps speeds. Furthermore, it complies with the newly ratified IEEE 802.3az Energy Efficient Ethernet (EEE) standard. This standard is significant as it is the first in Ethernet history to proactively address energy consumption reduction for networked devices. The IEEE 802.3 EEE standard defines mechanisms and protocols to lower the energy consumption of network links during periods of low utilization by transitioning interfaces into a low-power state without interrupting the network connection. Another aspect of the power-saving technology is its ability to reduce power consumption based on link status. If a port lacks a link—for instance, if no computer is connected or the connected computer is powered off—D-Link's Green Technology activates a "sleep mode," significantly cutting down the power used by that specific port.
The GO-SW-5E utilizes switching technology, which is a cost-effective method for increasing the total network capacity available to users on a Local Area Network (LAN). If an Ethernet network shows signs of congestion, such as low throughput, slow response times, or high collision rates, integrating a switch like the GO-SW-5E can significantly boost user throughput while preserving much of the existing network's cabling and workstation interface card infrastructure. This makes it a viable solution even for demanding applications like multimedia production and video conferencing. By dividing a local area network into different LAN segments, the switch increases capacity and reduces network loading. This segmentation is a common strategy for enhancing available bandwidth, ensuring that most network traffic remains within its segment, thereby benefiting from full-line speed bandwidth. Unlike traditional shared networking topologies used by hubs, where connected nodes compete for the same network bandwidth, the GO-SW-5E provides full-line speed and dedicated bandwidth for all connections. When two switching nodes communicate, they establish a dedicated channel, eliminating contention for network bandwidth with other nodes and substantially reducing the likelihood of traffic congestion. For Ethernet networks, the switch effectively resolves the issue of chaining hubs beyond the "two-repeater limit." It can segment parts of the network into distinct collision domains, enabling the expansion of an Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks. Switches that support both 10Mbps Ethernet and 100Mbps Fast Ethernet, like the GO-SW-5E, are also ideal for bridging between existing 10Mbps networks and newer 100Mbps networks. This switching LAN technology represents a notable advancement over previous generations of network hubs and bridges, which often suffered from higher latencies. While routers have also been used for LAN segmentation, their higher cost, complex setup, and maintenance requirements make them less practical. Today, switches offer an ideal solution for most local area network congestion issues.
The GO-SW-5E is a high-performance switch specifically designed for environments where network traffic and user numbers are constantly increasing. Its small, compact form factor makes it ideal for small to mid-sized workgroups and allows for installation in spaces with limited room. It offers immediate access to a rapidly expanding network through a comprehensive suite of user-reliable functions. The device is well-suited for deployment with multiple high-speed servers in 10Mbps or 100Mbps shared-bandwidth workgroups. With a maximum bandwidth of 200Mbps (in 100Mbps full-duplex mode), each port can provide workstations with a congestion-free data path for simultaneous access.
The GO-SW-5E is scalable, allowing for the cascading of two or more units. Since all five ports support 200Mbps, any port can be used to connect to an additional switch, effectively creating a Full-Duplex Fast Ethernet pipe. This makes the GO-SW-5E an excellent choice for departments or offices planning to upgrade to Fast Ethernet, as it can accommodate both 10Mbps and 100Mbps devices, offering a flexible solution for existing 10Mbps Ethernet workgroups. The switch employs dynamic memory allocation and store-and-forward switching to ensure efficient buffer allocation for each port. It also manages data flow between transmit and receive nodes to prevent packet loss. As an unmanaged 10/100Mbps Fast Ethernet switch, it provides effective solutions for the growing bandwidth demands of small Ethernet workgroups.
Key operational features include the Auto-MDI/MDI-X function, which supports automatic crossover detection. This "plug and play" capability means that either Crossover or Straight-Through CAT5 cables can be connected to any port without manual configuration. Each port also supports Nway Auto-negotiation, enabling automatic sensing of speed (10/100Mbps), which provides a flexible and automatic solution for network connectivity. Flow control is available on all ports, minimizing dropped packets by sending out collision signals when a port's receiving buffer is full. Additionally, the switch performs data filtering at wire-speed, eliminating all error packets, runts, and similar anomalies per port for both 100Mbps and 10Mbps operations.
For setup, the GO-SW-5E requires the power outlet to be within 1.82 meters (6 feet) of the switch. Users should visually inspect the DC power jack to ensure it is fully secured to the power adapter. It is crucial not to obstruct the ventilation holes on the sides of the switch, ensuring adequate airflow around the device. Heavy objects should not be placed on the switch. The device powers on immediately upon plugging its external power adapter into a power outlet, as it does not have a power button.
Connecting devices to the GO-SW-5E is straightforward. A computer can be connected using a two-pair Category 3, 4, or 5 UTP/STP Straight-Through or Crossover cable. Any of the five GO-SW-5E ports can accommodate a computer equipped with an RJ-45 10/100Mbps port. The LED indicators on the front panel provide visual feedback on the connection status. If the LED indicators do not light up after a proper connection, users should check the computer's Ethernet card, the cable, and the GO-SW-5E's conditions and connections. Similarly, a 10Mbps or 100BASE-TX hub can be connected to any GO-SW-5E port using a two-pair Category 3, 4, or 5 UTP/STP Straight-Through or Crossover cable, with a Category 5 cable being necessary for 100Mbps operation. The GO-SW-5E can also connect to other network devices such as switches, routers, or bridges using a two-pair Category 3, 4, or 5 UTP/STP Straight-Through or Crossover cable. For 100Mbps operation, a Category 5 cable is required. The connection can be made from any (MDI-X) port on the GO-SW-5E to any 10Mbps or 100Mbps (MDI-X) port on another switch or device.
Regarding port speed and duplex mode, the system automatically uses auto-negotiation to determine the transmission mode and detect the network speed (10Mbps or 100Mbps) for any new twisted-pair connection. If the attached device does not support auto-negotiation or has it disabled, an auto-sensing process is initiated, and the half-duplex mode is selected.
Maintenance is minimal due to the unmanaged nature of the switch. The device is designed for simple plug-and-play operation, requiring no complex configuration or ongoing software management. The LED indicators on the front panel serve as a primary diagnostic tool, with the green Power Indicator confirming the switch is receiving power, and the green Link/Act indicator showing an active connection and blinking during data transmission or reception. These visual cues help users quickly ascertain the operational status of the device and its connections. The robust design and automatic features, such as Auto-MDI/MDI-X and Nway Auto-negotiation, reduce the need for manual intervention and troubleshooting, making the GO-SW-5E a low-maintenance solution for expanding network capabilities.
