D-Link has announced a new family of managed metro Ethernet gigabit switches – the DGS-1210/ME Series. Available in 8, 24, and 48-port versions – with and without power over Ethernet (PoE) – these enhanced Layer 2+ switches are designed to support additional features often required by providers who offer Internet and video services to their business customers.
Specific metro Ethernet features found in the DGS-1210/ME Series include surge protection on the Gigabit ports, dying gasp, Link OAM, and redundant power options (on select models). Layer 2 switching features include port-based Q-in-Q, ACLs and other advanced security features, and ITU-T G.8032 Ethernet Ring Protection Switching (ERPS) with sub-50-ms protection and recovery. Management options include an intuitive web-based graphical user interface or a full-featured command line interface (CLI). DGS-1210/ME models are available with 8, 24 or 48 ports of 10/100/1000 RJ45 ports.
The PoE versions support IEEE standard 802.3at PoE+ on each port. The 8-port models offer an additional two ports of Gigabit fiber (SFP), while the 24 and 48-port versions support four additional Gigabit fiber ports.
