Cost-effective Gigabit Solution for Enterprise Backbone and Data Center Networking  PLANET GSW-2401 Gigabit Ethernet Switch provides 24 RJ45 10/100/1000Mbps ports for high-speed network connectivity. It can automatically identify and determine the correct transmission speed and half/full duplex mode of the attached devices with its 24 Gigabit ports that support 9K jumbo frame feature. Therefore, the GSW-2401 can handle extremely large amounts of data transmission in a secure topology linking to a backbone or high-power servers.   DIP Switch for Operation Mode Selection The new GSW-2401 offers “Standard”, “Flow Control Off”, “VLAN” or “Extend” mode. The GSW-2401 operates as a normal Gigabit Ethernet Switch in the “Standard” operation mode.       The “VLAN” operation mode features port-based VLAN function that can help to prevent the connected clients’ multicast or broadcast storm from influencing each other. In the “Extend” operation mode, the GSW-2401 operates on a per-port basis at 10Mbps duplex operation but can transmit data over a distance of up to 200 meters overcoming the 100m limit on Ethernet UTP cable. With this brand-new feature, the GSW-2401 provides an additional solution for distance extension, thus saving the cost of Ethernet cable installation. Its VLAN isolation function isolates each port so as to prevent broadcast storm and defend DHCP spoofing in the “Extend” operation mode.   DIP Switch Mode Function  Standard (default) This mode makes the Gigabit Ethernet Switch operate as a general switch and all ports operate at 10/100/1000Mbps auto-negotiation. Flow Control Off  This mode disables the Gigabit Ethernet Switch flow control function. VLAN  This mode makes the GSW-2401 operate as a VLAN isolation switch and 1. Port 1 to port 22 will isolate respectively. 2. Port 1 to port 22 can only communicate with port 23 and port 24 (uplink port).  Extend This mode makes the GSW-2401 operate as a distance extension switch and port 1 to port 8 can only transmit distance of 200m at speed of 10Mbps.   High Performance The GSW-2401 provides a high-performance switch architecture that is capable of providing the non-blocking switch fabric and wire-speed throughput as high as 48Gbps, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands.  Besides, the Flow Control function of the GSW-2401 enables routers and servers to directly connect to the Switch for fast and reliable data transfer. All the RJ45 copper interfaces of the GSW-2401 support 10/100/1000Mbps auto-negotiation for optimal speed detection through RJ45 Category 6, 5 or 5e cables. It also supports standard for auto-MDI/MDI-X that can detect the type of connection to any Ethernet device without requiring special straight or crossover cables.   Excellent Traffic Transmission The GSW-2401 supports Store-and-Forward forwarding scheme to ensure low latency and high data integrity, which eliminates unnecessary traffic and relieves congestion on critical network paths. With an intelligent address recognition algorithm, the GSW-2401 recognizes up to 8K different MAC addresses. The high data throughput and 48Gbps internal switching fabric make it ideal for most Gigabit environments, especially when network is upgraded to a Gigabit environment.    Fanless Design With its good ventilation design, the GSW-2401 is able to operate all along without a fan, thus reducing substantial power consumption and creating a noiseless environment. The GSW-2401 is definitely the best choice for any working environment without affecting its performance.
