D-Link DGS-3120-24PC/SI

Advanced Stackable Switch D-LINK DGS-3120-24PC 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 24 gigabit ports and four combo SFP ports. Also, you will enjoy a pair of 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. It is also important to note that ports support Power over Ethernet (PoE), which užmožňuje power other devices without the need for additional electrical connections

Switch D-LINK DGS-3120-24PC is aimed at small and medium-sized businesses that require a high level of network security and maximum uptime. Supports features such as Spanning Tree, Rapid Spanning Tree and Multiple Spanning Tree, Loopback Detection, and Broadcast Storm Control, that enhance network resilience against disruption. Features Ethernet Ring Protection Switching (ERPS) minimizes recovery time in the event of a loop. For load sharing and redundancy between switches/server offers a number of 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 from a computer that does not meet the safety criteria. D-LINK DGS-3120-24PC contains a rich set of multilayer QoS/CoS features to ensure that critical network services 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 your network from illegal IPv6 clients. The DGS-3120 is certified IPv6 Ready Logo Phase 2 from the IPv6 forum, a worldwide association to support IPv6. IPv6 Ready Logo Program ensures compatibility and interoperability of IPv6 products. Technology D-Link Single IP Management (SIM) simplifies and speeds up your management device that allows you to configure, monitor and manage several switches through a single IP address from any workstation with a Web browser.

D-Link is striving to take the lead in developing innovative and power-saving technology that does not sacrifice 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 length. Power-saving feature automatically powers down ports that have no link or link partner. The Smart Fan feature enables the built-in fans automatically at a certain temperature, providing continuous, reliable and eco-friendly operation of the switch.
