  The DES-3225G Standalone Ethernet switch is part of a new generation of Ethernet switches from D-Link adding rich functionality and wire-speed performance at the edge of networks with Ethernet backbones. Designed for flexible and cost-effective network growth, it offers more than just port expandability — it offers an impressive range of software features at an aggressive price point. The DES-3225G is part of a new family of switches that is the perfect complement to D-Link's family of multi-Gigabit Ethernet switches. D-Link now offers customers an end-to-end solution for an all-Ethernet architecture with the industry-leading performance of the DES-5600 or DES-6000 in the core and the rich feature set, easy management and low total cost of ownership of the DES-3225G, and DES-3624 Series at the edge. DES-3225G - Standalone Ethernet Switch The DES-3225G has a base configuration of 24 10/100TX ports, 2 of which are on a option module that can be replaced with 100Base-FX connections. In the back of the DES-3225G is a further high-performance expansion port which supports either a single port 1000BaseSX option module. Flexibility The DES-3225G base unit offers 24 ports of 10/100TX. Two ports on the front of the device there is a can be swapped to one of the following options: Option Modules DES-362FM - 2 port 100BaseFX (MT-RJ) DES-361FX - 1 port 100BaseFX (SC) There is one port on the rear of the unit, for an optional gigabit module, the DES-321G, for a full gigabit uplink to a server or even the backbone of your network. 12,000 MAC addresses: By supporting up to 12K MAC addresses, the DES-3225G switch has the flexibility of being used to connect end users directly, or as a switch between shared media devices (e.g. dual speed hubs). Auto-negotiating: Automatically detects and sets the speed, duplex, and flow-control for any 10Base-T or 100Base-TX port. Standards-Based Software The DES-3225G supports a broad range of the latest IEEE Ethernet standards offering the highest levels of functionality and easy interoperability with other vendors' equipment. Quality of Service (802.1p): Allows the switch to prioritize specific traffic flows over others. VLAN Identification (802.1Q): Allows the switch to direct traffic based on non-proprietary virtual local area networks (VLANs). Spanning Tree (802.1d): Standards-based link redundancy protocol that allows redundant links to be established to backup primary link while preventing network loops. Flow Control (802.3x): Helps monitor and regulate inbound switch traffic to ensure that traffic levels can be handled by the switch. IP multicast (IGMP): IP multicast traffic standard. Broadcast Storm control, with SNMP management trap and user configurable threshold. High Performance The DES-3225G is a wire-speed, non-blocking Ethernet switch. It also has the following features to enhance network performance: Link aggregation for higher switch-to-switch throughput and link-level redundancy, including support for Cisco Fast EtherChannel. Gigabit Ethernet: The rear high-speed expansion port of the DES-3225G supports single port versions of the 1000Base-SX expansion module. Manageability Web management: Allows you to configure the switch from any PC on the network with a Web browser. SNMP management: Industry standard enterprise network management support. Mini-RMON (groups 1,2,3,9): Provides advanced monitoring capabilities. Port mirroring: Allows the network administrator to monitor traffic on one port using another switched port attached to a network analyzer. Warranty D-Link offers a 1-year warranty on all DES-3225G Models.
