5-Port 10/100Mbps Fast Ethernet Switch


  • Overview
  • High-speed 10/100Mbps Workgroup Switch
    PLANET Fast Ethernet Switch FSD-503 provides business and home users with a cost-effective integrated system of small-office / home-office networking. It is with compact-sized metal case design and just right for the network of 10 to 50 users.

    Stable Fast Ethernet Switch Performance
    The FSD-503 also supports Store-and-Forward forwarding scheme to ensure low latency and high data integrity. The high performance throughput (filtering / forwarding rate: 14,880 packets per second in 10Mbps, and 148,800 packets per second in 100Mbps) and built-in packet buffer help the FSD-503 to boost bandwidth, eliminate unnecessary traffic, and relieve congestion on your critical server path. With an intelligent address recognition algorithm, the FSD-503 could recognize up to a 2K different MAC addresses and provide 1Gbps switching capacity, which makes the FSD-503 the best in wire-speed packet transfer performance without risk of packet loss.

    Flexible Desktop Size Design
    The FSD-503 is a fancy-shaped standard metal model that nicely fits in a space-limited environment. With concepts of “easy to install and use“, “compact sized design“, and “simple troubleshooting“, the FSD-503 provides cost-conscious business and home users with a flexible yet cost-effective SOHO / Home networking.

    Power Energy Saving
    With one power ON/OFF button designed on the rear panel of the FSD-503, it can help users to reduce unnecessary power energy loss while the FSD-503 operation is OFF.

    Plug & Play and Easy Installation
    All RJ-45 copper interfaces in the FSD-503 support 10/100Mbps auto-negotiation for optimal speed detection through RJ-45 Category 5/5e cables. Supporting standard for auto-MDI/MDI-X can detect the type of connection to any Ethernet device without requiring special straight-through or crossover cables. The Flow Control function allows the FSD-503 to support routers and servers for direct connection to this switch with fast and reliable data transfer.

  • Applications
  • Ideal Switch for Home / SOHO Network
    With five 10/100Mbps ports, the FSD-503 provides a cost-effective and high-performance solution for Home and SOHO network applications. To segment the network and ease the network traffic, the FSD-503 is perfect for SOHO switched networks as the friendly network backbone. In addition, the network status can be monitored at a glance by the FSD-503 providing array LED indicators.
