Highlights for D-link DSS-24+ High Performance Unmanaged Layer 2 Switch

  • Product Type:Ethernet Switch
  • Number of Ports:24

D-Link's DSS-24+ is a high performance unmanaged Layer 2 Switch that provides users with 24 10/100Mbps Fast Ethernet ports with NWay auto-negotiation per port. Designed with a new chipset, the DSS-24+ can automatically detect either MDI/MDIX cable type through any of the Ethernet ports, which eliminates the need for an uplink port. The DSS-24+ includes support for an optional 2-port 100BASE-FX module with an "SC connector" increasing cable connectivity to other servers and switches. The DSS-24+ is targeted for both small office and small business environments.

The DSS-24+ 24 10/100 Mbps ports adheres to IEEE 802.3, 802.3u, and 802.3x standards, which specify 10Base-T, 100Base-TX and 100BASE-FX Ethernet technologies. With the DSS-24+ switching function, Store and Forward is implemented with Rate Adaptation Protocol. (RAP) is an end-to-end rate-based congestion control mechanism, which ensures data integrity when packets are transmitted. The switching capability of the DSS-24+ allots 256Kbytes of allocated memory buffer per 8-ports. As a result, a complete frame checking and error-filtering scheme helps prevent any packets with errors from being transmitted among any broadcast segments. The DSS-24+ also supports Backpressure and pause frame-based flow control at half duplex mode schemes to ensure zero packet loss by sending out collision signals when the port's receiving buffer is full under heavy traffic congestion.

The DSS-24+ switching function forwards data packets at wire speeds for both 10Mbps and 100Mbps. In addition, the DSS-24+ data filtering design eliminates all errors of packets at each port at wire speeds of 10Mbps and 100Mbps. As a switching solution, the DSS-24+ initiates a MAC address-learning table aging features. MAC addresses are automatically updated reducing any broadcast among network segments, which provides dynamic filtering through auto-learned MAC addresses and static filtering.

With its rack mount design and ease of installation, the DSS-24+ switch provides a cost effective way of increasing total bandwidth where network traffic is continuously increasing.

  • Description

    The DSS-24+ is a high performance unmanaged Layer 2 switch designed to increase cable connectivity to distant servers or backbones and is an ideal solution for small business environments.D-Link’s DSS-24+ is a high performance unmanaged Layer 2 Switch that provides users with 24 10/100Mbps Fast Ethernet ports and optional fiber uplinks for distant connections. The DSS-24+ is designed to increase cable connectivity to distant servers or backbones, targeted for both small offices and small business environments.
  • High Performance Wire-speed Architecture

    The DSS-24+ delivers superior performance and outstanding value. With a switching capacity of up to 5.2Gbps and full-duplex wire-speed forwarding, the DSS-24+ is an ideal solution for the most demanding environment. It can be used as a cost-effective wiring closet solution or a high performance backbone aggregation device.

  • Easy to Install and Maintain

    The auto features of this switch make installation plug & play and hassle-free. No configuration is required. Auto-MDI/MDI-X crossover on all ports eliminates the need for crossover cables for connection to another switch or hub. Auto-negotiation on each port senses the link speed of a network device (either 10 or 100Mbps) and intelligently adjusts for compatibility and optimal performance. It also features diagnostic LEDs which display status and activity, allowing you to quickly detect and correct problems on the network. The DSS-24+ has no fans, it is suitable for an office environment.

  • Optional Fiber Uplinks to Protect Investment

    The DSS-24+ has an optional slot that supports a 2-port 100BASE-FX MMF module that can connect to distant backbones up to two kilometers away.
