The DES-1228P provides built-in 802.3af Power over Ethernet (PoE) for sites needing to run power over the network cables. Each of the 24 Fast Ethernet ports provides up to 15.4W power for devices such as wireless Access Points, IP phones and cameras, allowing them to be deployed in difficult places where AC power outlets are not readily available. With powerful switch fabric and abundant processing memory, the DES-1228P provides wire-speed high performance for departments and workgroups. This switch includes support functions such as IGMP Snooping, QoS, 802.1Q VLAN, port mirroring, Spanning Tree and port trunks to enhance performance and network resiliency. In addition, the switch supports 802.1p Priority Queues, enabling users to run bandwidth-sensitive applications such as streaming multimedia and VoIP on the network. These functions allow the switch to work seamlessly with managed VLAN and 802.1p traffic on the network. The switch provides MAC address filters to screen access to the network. It supports 802.1X Port-based Authentication, allowing the network to be configured with external RADIUS servers. Additional features like the D-Link Safeguard Engine protect the switch against traffic flooding caused by virus/worm outbreaks. Switch configuration and management are provided by the SmartConsole utility or a web-based GUI. With full colour graphic pictures, diagrams, and easy to understand navigation menus, SmartConsole is an easy way to access the switch from a local PC. It includes useful features like auto-discovery for automatic display of all DES-1228/1252 switches running on the network, Monitor List for status and trap messages and Trap View for system events, device boot up, abnormal data transfer errors and illegal login. The web-based GUI allows switch access from any location on the network or from a remote site, using a web-browser. It allows extensive switch configuration setting, which can be backed up for duplication in other switches. In addition, built-in MIBs allow administrators to integrate the switch with other third-party devices for management in an SNMP environment. |
