FAQ
What is the total PoE budget of the D-Link DGS-1520-28MP switch?
The D-Link DGS-1520-28MP has a total PoE budget of 740 watts. This budget is allocated across its 24 PoE-capable ports (20 Gigabit Ethernet PoE and 4 2.5 Gigabit Ethernet PoE), allowing it to power multiple PoE+ or PoE++ devices such as wireless access points, IP cameras, and VoIP phones simultaneously without requiring separate power adapters. The switch dynamically manages power distribution to connected devices based on their requirements.
How many 10 Gigabit ports does this switch include?
This switch includes two 10 Gigabit Ethernet network ports as built-in uplinks. Additionally, it features two SFP+ expansion slots that can support 10 Gigabit fiber or copper transceivers, providing up to four potential 10G connections. The 10G ports are designed for high-speed backbone links to servers, core switches, or storage systems, enhancing overall network throughput and reducing bottlenecks in data-intensive environments.
Is the DGS-1520-28MP a Layer 2 or Layer 3 switch?
The DGS-1520-28MP is a Layer 3 managed switch. It supports Layer 3 routing protocols, allowing it to perform inter-VLAN routing, implement access control lists (ACLs), and apply quality of service (QoS) policies based on IP addresses. This makes it suitable for more complex network architectures where segmentation, security, and traffic management between subnets are required, beyond basic Layer 2 switching functionality.
Can this switch be mounted in a standard server rack?
Yes, the DGS-1520-28MP is designed for 1U rack mounting and is compatible with standard 19-inch server racks. Its dimensions are 1.73 inches (44 mm) in height, 12.15 inches (308.50 mm) in width, and 17.36 inches (441 mm) in depth, ensuring a compact fit that maximizes rack space. The switch includes mounting brackets and supports tool-less installation for easy deployment in data centers, network closets, or server rooms.
Does the switch support redundant power supplies?
Yes, the DGS-1520-28MP supports redundant power supplies. This feature allows for the installation of an optional secondary power supply unit to provide backup power in case the primary unit fails, enhancing network uptime and reliability for critical applications. The switch can automatically switch to the redundant power source without interrupting operation, making it suitable for environments where continuous availability is essential.
What types of cables are compatible with this switch?
The switch supports both twisted pair copper cables and optical fiber cables. For copper connections, it is compatible with Cat5e, Cat6, or higher cables for distances up to 100 meters, supporting network technologies like 10/100/1000Base-T, 2.5GBase-T, and 10GBase-T. For fiber connections, the two SFP+ slots can accommodate SFP+ transceivers for 10GBase-X standards, enabling longer-distance links or use in electrically noisy environments where fiber is preferred.
