This cost effective Gigabit Switch provides an affordable solution for administrators to upgrade their networks to high
speed Gigabit connections. The dedicated stacking ports offer up to 40G bi-directional bandwidth, which makes the DGS-
3420 Series also suitable as a backbone solution for SMBs. The advanced ACL and user authentication functions on the
Switch extend the network security coverage from core to the edge. A unique D-Link Safeguard Engine protects the DGS-
3420 Series from the threat of worms and viruses, thereby increasing overall reliability, serviceability, and availability
The Switch has a combination of 1000BASE-T ports and SFP ports that may be used in uplinking various network devices
to the Switch, including PCs, hubs and other switches to provide a gigabit Ethernet uplink in full-duplex mode. The SFP
(Small Form Factor Portable) combo ports are used with fiber-optical transceiver cabling in order to uplink various other
networking devices for a gigabit link that may span great distances.
