D-Link DMS-3130-30PS/E - 30-Port Managed Layer 3 Stackable Multi-Gigabit PoE Switch, Black

The D-Link DMS-3130-30PS/E is a 30-port, Layer 3 stackable, multi-gigabit managed PoE switch for enterprise networks. It features 26 RJ-45 copper ports supporting 2.5G Ethernet and four SFP module slots for high-bandwidth fiber uplinks. With a 400 Gbit/s switching capacity, it supports high traffic loads, allowing for the connection of multi-gigabit wireless access points, network cameras, and workstations without bottlenecks. The unit is rated for a maximum power consumption of 1211.5 W.

The 1U switch mounts in standard server racks and uses two internal fans for cooling. Infrastructure can be scaled by stacking up to nine units, which simplifies configuration. The switch is managed via a web interface and supports inter-network communication through IP and static routing. Traffic and security are controlled via Access Control Lists (ACLs), ARP inspection, and IP/MAC/port binding. The device also supports redundant power supplies (RPS) to ensure continuous operation in the event of a power failure.

• Total PoE budget of 740 W across 24 ports, including 16 PoE+ ports.
• Forwarding rate of 298 Mpps.
• Support for up to 4,000 active VLANs, including MAC-based, multicast, private, and voice VLAN configurations.
• MAC address table of 32,768 entries with a 4 MB packet buffer.
• Mean time between failures (MTBF) of 277,223 hours.
