5. Product OverviewModel Description

6. Product Overview Product Briefing • DGS-3420 is an ideal aggregation/edge solution for Enterprise, Campus & Telco or core for SMB applications • Provides L3 features including static route and RIP • Provides comprehensive IPv6 support including IPv6 Management, DHCPv6, IPv6 Neighbor Discovery (ND), DHCPv6, RIPng, IPv6 Tunneling • RichAAA, access control features including Compound Authentication, Identity driven policy (VLAN, ACL, QoS) assignment help administrators well-manage various requirements of the networks • Features with advanced Green Technology including Power Saving and Time based PoE • Provides high reliability with comprehensive OAM features including ERPS (Ethernet Ring Protection Switching), DULD (D-link Unidirectional Link Detection), CFM ( 802.1ag Connectivity Fault Management) and ITU-T Y.1731 • Q in Q and VLAN Translationsolve the 4K limitation of 802.1Q VLAN groups, it lets large ISPs enable L2 Virtual Private Networks and transparent LANs for their customers, which will connect two or more customer LANs without complicating configurations on the client-side • For the emerging worm/virus threats, D-Link Safeguard Engine can protect the device from overwhelmed by the flood traffic, hence it increases the robustness and availability of network infrastructure

7. Product Overview Product Briefing • Advanced hardware design with excellent performance. • 4 10GE SFP+ ports provide high flexibility for physical stacking or uplink usage • 16K MAC address table, 1K H/W routing entries • Supports 802.3af (PoE) and 802.3at (PoE+) for all ports of PoE model • Smart Fan • Power saving: Internal heat sensor monitors switch’s temperature and adjusts the fan speed accordingly • Improves the MTBF with slower fan speed and reduces the noise • SD Card Slot • Easy to store and restore file with portable SD card (like FW, configuration file, boot image, syslog or other files) • External Alarm Connector • Provides digital I/O design on external alarm connector. It can provide better security protection. • With digital in, DGS-3420 can receive events detected by external sensors (e.g. temperature, smoking or anti-theft sensor). The switch can send a trap out to report the issue. • With digital out, DGS-3420 can activate external air-conditioner/fan or ring the bell based on the condition customer defined.
