Advanced hardware design with excellent performance. Support 802.3af (PoE) and 802.3at (PoE Plus) for all ports 1 High uplink/stacking bandwidth 4 10GE SFP+ ports provide up to 40G bandwidth. It provides high flexibility for physical stacking or uplink application use. Enlarge MAC address table to 32K (DGS-3600 series is 16K) Smart Fan Power saving: Internal heat sensor monitors switch’s temperature and adjusts the fan speed accordingly. Improve the MTBF with slower fan speed and reduce the noise 2 External SD Card Easy to store and restore file with portable SD card (like FW, configuration file, boot image, syslog or other files). External Alarm Port 3 Provides digital I/O design on external alarm port. It can provide better security protection. With digital in, DGS-3620 can receive events detected by external sensors (eg. temperature, smoking or anti-theft sensor). The switch can send a trap/log out to report the issue. With digital out, DGS-3620 can activate external air-conditioner/fan or ring the bell based on the condition customer defined. Product Overview Product Briefing

Advanced L3 Features Provides advanced L3 features including IPv4/v6 routing, Packet routing and protocol filtering/inspection, which make the Switch act even as a Layer 4 switches Comprehensive IPv6 support Provides comprehensive IPv6 support including IPv6 Tunnel, ICMPv6, IPv6 Neighbor Discovery (ND), DHCPv6, RIPng and OSPFv3 IPv6 Ready Logo Phase I and Phase II High availability, security and reliability Rich AAA, access control features help administrators well-manage the visitors of the networks Various attack prevention features and redundancy protocols D-link Green Ethernet Technology First L3 Gigabit Switch provides advanced Power Saving, Smart Fan, Time based PoE Product Overview Product Briefing

Technology Briefing MPLS MPLS * provides the “Best-effort Delivery”. It speeds up the data delivery, improves the packet QoS and solves the burden of IP routing MPLS adopted the core idea of ATM. It locates itself between IP layer and data link layer and takes the responsibility of carrying any traffic over itself What MPLS learns from ATM: Thinking of label switching Using Local Label instead of global IP address Note: DGS-3620 will support MPLS in the future IP

Technology Briefing MPLS L2 VPN: VPWS & VPLS VPWS (Virtual Private Wire Services) is point-to-point. VPLS (Virtual private LAN service) is multipoint. Carrier Ethernet logically connects to MPLS core via Q-tag, Q-in-Q or simple p2p MPLS tunnels MPLS core carries pure Ethernet over MPLS without customer Layer 3 routing control Customer routing information is NOT exposed to Service Provider
