48-Port Gigabit L2 Switch with 4 Combo SFP and Management
The DGS-3048 switch addresses today's diverse business and IT requirements through robust support of standards based network management protocols (SNMP/RMON/Bootp/Telnet/Web) and port mirroring. By supporting standards-based network management protocols, this device can be easily integrated with most third-party network management products. The switch provides full duplex forwarding, 8k MAC addresses and the ability to classify and mark traffic based on 802.1p or DSCP (future release) into priority queues.
DGS-3048 brings enterprise functions to a new level of affordability without compromising advanced features, such as QoS, Multicast, VLANs, Port Trunking, Port Mirroring, Spanning Tree, Security, and Network Management. These features facilitate the deployment of applications across an enterprise, including: VoIP, streaming media, and multicast content delivery (IP video, software deployment, etc.). Security features include 802.1x port based access control, and support for RADIUS and TACACS+ servers.
Port Trunk & Redundancy Support
The switch can be used as a cost-effective Gigabit to the desktop solution or high performance backbone aggregation devices. With 802.3ad Link Aggregation support, multiple ports can be combined into a multi-link for higher bandwidth connections to servers or the network backbone. The switch can be connected to redundant power supply to maximize network uptime. In case of a power failure, the external power unit will automatically provide the required power to ensure continuous operation.
With 4 SFP modules, the DGS-3048 can easily adapt to changes in customer media requirements without the need to perform an expensive upgrade. Users can migrate to more advanced solutions in the future, while still protecting a portion of their original investment.
