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

17. 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 47.1 47.2 47.3 1 3 1 2 1 2 3 3 IP 47.1.1.1 50 40
