D-Link DGS-1210-52MP 48-Port PoE Gigabit Smart Switch

DGS-1210 switch is capable of conserving power without sacrificing operational performance or functionality by using D-Link Green 3.0 technology. Using the Energy Efficient Ethernet standard, the network will automatically decrease the power usage when traffic is low with no setup required. For environments not fully supporting the standard, DGS-1210 switch offers advanced power-saving settings including port shutoff and standby, LED shutoff, and system hibernation based on custom scheduling profiles. The profiles can also be applied to the PoE switch so that there is no unnecessary power consumption during off-hours. The DGS-1210 series switch can also detect the length of connected cables to automatically reduce power usage on shorter cable connections.

The process of setting up IP surveillance and VoIP on a network is automated with the D-Link Smart switch. Auto Surveillance VLAN (ASV) consolidates data and surveillance video transmission through the network, sparing businesses the expense of maintaining dedicated facilities. ASV also protects the quality of real-time video by grouping IP surveillance devices on a single high priority VLAN. This ensures that surveillance video streams will not be affected when ordinary data traffic is at their high levels. Similarly, the Auto Voice VLAN guarantees clear audio quality and efficient transmission for all voice communication.

Equipped with a complete lineup of L2 features, the DGS-1210 series switch includes 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 2000 Mbps 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. The cable diagnostic feature is designed primarily for administrators and customer service representatives, and can rapidly discover the type of error and determine the cable quality.

D-Link's safeguard engine protects the switch against traffic flooding caused by virus attacks. The switch also supports 802.1x port-based authentication, allowing the network clients to be authenticated through external RADIUS servers. In addition, the Access Control List (ACL) feature enhances network security and protects the network by screening traffic from illegal MAC or IP addresses. ARP spoofing prevention prevents malicious intruders from sending massive fake ARP messages through a manipulated source. This protects important data from being stolen by man-in-the-middle attacks, and prevents wasting CPU cycles on these packets. For added security, the DHCP server screening feature blocks rogue DHCP server packets from user ports to prevent unauthorised IP assignment.
