D-Link DGS-3120-48TC/SI

Advanced Stackable Switch D-LINK DGS-3120-48TC is safe to connect end users in a network of small and medium-sized businesses to large enterprises.It supports physical stacking, multicast transmission and enhanced security, making them an ideal Gigabit access layer solution.There are 44 ports and four Gigabit SFP combo ports.Also, you will be pleased by two 10Gbit stacking ports.These switches are also equipped with an SD card slot, which allows the boot firmware and upload configuration files directly from the SD card.

Switch D-LINK DGS-3120-48TC is aimed at small and medium-sized businesses that require a high level of network security and maximum uptime.Support functions such as Spanning Tree, Rapid Spanning Tree and Multiple Spanning Tree, Loopback Detection, and Broadcast Storm Control, that enhance network resilience against disruption.Function Ethernet Ring Protection Switching (Erps) to minimize recovery time in the event of a loop.For load sharing and redundancy between switches/server offers many DGS-3120 dynamic port trunking.

The switch supports authentication mechanisms and security policies that can be applied individually to each connected host.NAP is a technology for enforcing network policy that allows administrators to protect network resources against computers that do not meet the established safety criteria.D-LINK DGS-3120-48TC contains an extensive set of multilayer QoS/CoS features to ensure that intensive services on the quality of transmission, such as VoIP, video conferencing, IPTV and IP surveillance are served with high priority.

Switch DGS-3120 is fully compliant with the future IPv6 networks.Supports IPv6 security features to protect the network from illegal IPv6 clients.The DGS-3120 is certified IPv6 Ready Logo Phase 2 from the IPv6 forum organization, a worldwide association to support IPv6.IPv6 Ready Logo Program ensures compatibility and interoperability of IPv6 products.D-Link Single IP Management (SIM) simplifies and speeds up your management by allowing you to configure, monitor and manage several switches through a single IP address from any workstation with a web browser.

D-Link is committed to taking the lead in developing innovative and energy-efficient technologies that do not degrade operational performance or functionality.Switch DGS-3120 incorporates D-Link Green, which includes a power saving mode, fan control, lower heat emission and detection of cable lengths.Power-saving feature automatically shuts down ports that are not connected or not communicating.Smart Fan automatically switches built fans at a certain temperature to ensure the long-term, reliable and environmentally friendly operation of the switch.
