D-Link Web Smart 8-Port Gigabit PoE Switch

The D-Link XD-NBPA10051 is the latest Web Smart switch to feature D-Link Green technology. Equipped with 8 10/100/1000 Mbps PoE ports and two combo 10/100/1000 BASE-T/SFP ports, the XD-NBPA10051 integrates advanced management and security functions that provide performance and scalability. Management options for the XD-NBPA10051 include SNMP, Web Management, SmartConsole Utility, and Compact Command Lines. The series also supports ACL filtering and the D-Link Safeguard Engine . The XD-NBPA10051 uses Auto Voice VLAN, ensuring higher priority for voice traffic. The XD-NBPA10051 comes with a fanless design in a compact 13-inch desktop enclosure, which allows for quieter operation and guarantees an extended lifetime. Note: As of June of 2015, D-Link has changed the design of the XD-NBPA10051 10-port PoE switch"”moving form a 10-port to an 8-port design, while keeping the same part number. If you recently purchased this D-Link PoE switch model, the change will affect the number of devices supported by the unit. D-Link GreenD-Link is continuously striving to take the lead in developing innovative technology that allows for power saving without sacrificing operational performance or functionality. The XD-NBPA10051 automatically detects the length of connected cables and can adjust power usage by saving energy on shorter cable connections of up to 20 meters. Power saving by link status helps to further save energy by automatically switching ports without a link to sleep mode and thus drastically reducing power consumption. The XD-NBPA10051 takes the approach to green IT and power saving one step further by incorporating a special chipset with advanced silicon technology. Seamless IntegrationThe XD-NBPA10051 comes with Ethernet and Gigabit copper ports capable of connecting to existing Cat.5 twisted-pair cables. Additionally, the last two ports of the XD-NBPA10051 combine SFP and copper connectivity into one port and therefore provide a more flexible solution for upstream or downstream server connections via fiber interface. Using the default presets, the administrator can quickly set up without worrying about reconfiguring any settings and providing easy access for the user. Extensive Layer 2 FeaturesEquipped with a complete lineup of L2 features, these switches include IGMP Snooping, Port Mirroring, Spanning Tree and Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfer. At 2000Mbps Full Duplex, the Gigabit ports provide high-speed data pipes to servers with minimum data transfer loss. Network maintenance features include Loopback Detection and Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port and automatically shut down the affected port. Cable Diagnostics is designed for network administrators to quickly examine the quality of the copper cables and determine the type of cable error. QoS, Bandwidth ControlThe switch is perfect for deployment in a VoIP environment, as they support Auto Voice VLAN and Differentiated Services Code Point (DSCP) QoS for VoIP application. Auto Voice VLAN will automatically place voice traffic from an IP phone to an assigned VLAN and by doing so enhance the VoIP service. With a higher priority and individual VLAN, this feature guarantees the quality and security of VoIP traffic. DSCP marks parts of an IP packet, enabling different levels of service to be assigned for network traffic. With Bandwidth Control, the network administrator can reserve bandwidth for important functions that require a larger bandwidth or might have higher priority. Secure your NetworkThe innovative D-Link Safeguard Engine function protects the switch against traffic flooding caused by virus attacks. The switch can also support 802.1X port-based authentication, allowing the network to be authenticated through external RADIUS servers. In addition, the Access Control List (ACL) feature enhances network security and helps to protect the internal IT network. The XD-NBPA10051 includes ARP Spoofing Prevention, which protects from attacks on the Ethernet network that may allow an intruder to sniff data frames on a LAN, modify traffic, or bring traffic to a halt altogether by sending fake ARP messages to the network. To prevent ARP Spoofing attacks, the switch uses Packet Control ACLs to block invalid packets that contain fake ARP messages. For added security, the DHCP Server Screening feature screens rogue DHCP server packets from user ports to prevent unauthorized IP assignment. Versatile ManagementThe XD-NBPA10051 provides a SmartConsole Utility and a web-based management interface that enable administrators to remotely control their network down to the port level. The SmartConsole easily allows customers to discover multiple D-Link Web Smart Switches within the same L2 network segment. With this utility, users do not need to change the IP address of their PC and it also pr
