D-link DGS-1510-28P/E PoE M Gigabit Stack cijene

The DGS1510 Series Gigabit Stackable Smart Managed Switches include models with 16, 24 and 48 ports of 10/100/1000 Mbps plus two Gigabit SFP and two 10G SFP+ ports, as well as a model with 24 PoE ports 10/100/1000Mbps ports plus two Gigabit SFP and two 10G ports. With its 10G SFP+ ports, the DGS1510 series is particularly suitable for use in the core area of small and mediumsized business networks with the typical 10G uplinks and 10G servers. In medium to large enterprise networks, they can serve as a connection between core and edge switches.
The DGS1510 Series Gigabit Stackable Smart Managed Switches also include a PoE switch for businesses that want to power VoIP phones, wireless access points, or network cameras. The DGS151028P is a PoE switch whose 24 PoE ports deliver an output power of up to 30 W according to IEEE 802.3at. The model offers greater flexibility in powering a variety of devices and at manageable installation costs.
The DGS1510 series equipped with DLink Green 3.0 is characterized by low power consumption and high efficiency and complies with the IEEE standard 802.3az Energy Efficient Ethernet. Support for IPv6 management and configurations ensures your network remains protected even after upgrading from IPv4 to IPv6. With multiple management options, the DGS1510 Series enables rapid infrastructure deployment and expansion, as well as seamless feature upgrades. Designed for small to mediumsized businesses, the DGS1510 Series offers functionality, security and manageability at a fraction of the cost.

Two stacking/uplink ports with 10G SFP+
Depending on whether a linear or faulttolerant ring topology is implemented, users can also use one or two 10 Gigabit SFP+ ports to create a physical stack. Six units or 288 Gigabit ports can be configured in a stack with direct cable connections to costeffectively deliver high bandwidth with the DGS1510 Series devices. In addition, it is possible to mix different models of the DGS1510 series in a stack, which enables simple, bundled configuration, management and troubleshooting.

flexibility and scalability
The DGS1510 Series supports virtual stacking with DLink's Single IP Management (SIM). Up to 32 devices can be addressed via a single IP. This simplifies management of small workgroups or wiring closets and allows the network to scale to handle increases in bandwidth demands. SIM not only reduces the number of IP addresses required on the network, but also allows switches to be stacked over Ethernet rather than through physical uplink or stacking ports. This not only eliminates the need for special stacking cables, but also the distance limits that usually limit the possible topologies with other stacking technologies.

Extensive Layer 2 capabilities
The switches are fully equipped with Layer 2 features including IGMP snooping, port mirroring, spanning tree and Link Layer Discovery Protocol (LLDP). Flow control according to IEEE 802.3x enables a direct connection between server and switch for fast and reliable data transmission. With 2,000 Mbit/s in full duplex operation, the gigabit ports provide servers with highspeed data channels with minimal loss rate. Loopback detection and cable diagnostics are useful for network maintenance. Loopback detection automatically disables ports and VLANs when a loop is detected on that port or VLAN. With the cable diagnostics features, administrators and account managers can quickly identify the nature of a cable fault and assess cable quality.

QoS, bandwidth management
The DGS1510 Series supports Auto Surveillance VLAN (ASV) and Auto Voice VLAN, which are ideal for video surveillance and VoIP installations. Auto Surveillance VLAN is an innovative technology built into the DLink DGS1510 series switches. This technology enables data and video signals to be transmitted via a single switch. Companies therefore save additional investments in dedicated hardware and resources. ASV stands for highquality, realtime video transmission for monitoring and control purposes without sacrificing conventional data transmission. Auto Voice VLAN enhances VoIP by automatically mapping telephony traffic from an IP phone to a VLAN. Due to the higher priority and its own VLAN, this function ensures the quality and security of the VoIP data traffic. In addition, the DSCP markings of Ethernet packets allow different quality levels to be assigned to network traffic. Telephony and video packages have priority over other packages. With bandwidth management, bandwidth can also be reserved for important functions that require more bandwidth or higher priority.

Securing the network
DLink's innovative Safeguard Engine protects the switches from virus flooding attacks. In addition, the switches support authentication at port level according to 802.1X, which enables authentication in the network using external RADIUS servers. The Access Control List (ACL) feature increases network security and protects the internal network by screening incoming traffic based on MAC or IP addresses. The DGS1510 series features ARP spoofing protection that protects the Ethernet network by preventing intruders from eavesdropping on data frames, manipulating traffic, and blocking the network with forged ARP messages. The switch uses packet control ACLs to block invalid packets with bogus ARP messages, preventing ARP spoofing attacks. For added security, the DHCP server screening feature detects bogus DHCP server packets sent from user ports, preventing illegal IP assignments.

Flexible management
The DGS1510 Series supports the DLink Network Assistant utility and a web interface that allows administrators to remotely control networks down to the port level. DLink Network Assistant easily discovers multiple DLink DGS1510 series switches within a Layer 2 network segment. Users don't need to change their PC's IP address. It also simplifies the initial setup of DGS1510 Series switches. Switches within the same Layer 2 network segment that are connected to the user's local PC are displayed on the screen, ready for access. This allows extensive switch configuration and basic configuration of discovered devices, including password change and firmware upgrade. The DGS1510 Series also supports DView 6.0 and a powerful command line interface available through the console port. DView 6.0 is a network management system that allows central management of important network characteristics such as availability, reliability, resilience and security. The switches can be managed from the command line via the console port or via telnet. Changes to basic settings, passwords, configuration files and the firmware can also be made effortlessly in this way.

Layer 3 traffic management
The DGS1510 series supports static routing. This allows segmentation of the network into workgroups and communication between different VLANs without sacrificing application performance. These features increase network efficiency by freeing the router from internal traffic and freeing it for external traffic and security functions.

Ready for IPv6
The DGS1510 Series is IPv6 ready and supports a range of IPv6 features such as MLD snooping, ACL/QoS for IPv6 and IMPBv6. This ensures seamless integration into nextgeneration networks. In addition, the DGS1510 Series offers dualstack support for IPv4 and IPv6, allowing the switches to act as a bridge between IPv4 and IPv6 networks. In addition, all devices in the DGS1510 series are certified with the "IPv6 Ready, Phase 2" logo, which guarantees interoperability in IPv6 environments.

Energy saving
Thanks to DLink Green 3.0 technology, the DGS1510 series switches save energy without sacrificing performance and features. With the Energy Efficient Ethernet standard 802.3az, the power consumption of the network is reduced automatically and without further configuration when data traffic is low. For environments that don't fully support the standard, the DGS1510 series switches are equipped with advanced powersaving features, including port power down, LED power down, and system sleep controlled with userdefined profiles. The profiles can also be used on the PoE switch, so power is not wasted unnecessarily outside of business hours.
