Network switch D-Link DGS-3000-28L

The network switch D-Link DGS-3000-28L is included in the line of level 2 managed switches and is intended for use in Metro Ethernet networks. The switch is equipped with 4 10GBase-X SFP + ports, which guarantees high performance when aggregating a large number of gigabit connections. The model is made in a case with a height of 1U and is suitable for both desktop installation and installation in a telecommunications cabinet.

Reliability. All Ethernet ports of the DGS-3000-28L switch are equipped with built-in protection against static electricity up to 6 kV, which allows you to protect the device from voltage surges, especially if the Ethernet cables are located in open space or in old buildings. In case of interruptions in the power supply, the switch has an additional connector for connecting a backup power source DPS-200A / 500A and DPS-500DC / B1 or a 12 V DC power source. To ensure fault tolerance of Ethernet channels, the switch supports protocols 802.1D Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP) and 802.1s Multiple Spanning Tree (MSTP), the use of which allows automatic reservation of data transmission routes.

Using this functionality ensures transmission and reception of frames even in the event of network failures. The switches also support Ethernet Ring Protection Switching (ERPS, ITU-T G.8032) technology, thanks to which the recovery time of the ring after a failure does not exceed 50 ms. Using the Loopback Detection (LBD) function prevents congestion on uncontrolled network segments that are administered by subscribers or built on the basis of unmanaged switches.

In addition, the DGS-3000-28L switch supports port aggregation functionality based on the 802.1AX standard, the use of which allows you to combine several ports into a group, while increasing the bandwidth and increasing the fault tolerance of connections to ensure uninterrupted operation and load distribution among several network devices.
