D-Link DIS-300G-8PSW - Managed Industrial Gigabit Power over Ethernet Switch, Black

The D-Link DIS-300G-8PSW is a Layer 2 managed industrial switch designed to connect and power devices in industrial environments. The unit features six Gigabit RJ-45 ports and two LC SFP slots for fiber uplinks. Four of the copper ports support Power over Ethernet (PoE) for direct connections to IP cameras, wireless access points, or factory automation hardware. By providing power through the data cable, the switch eliminates the need for external power injectors. On-site traffic processing allows for segmentation and control within industrial local area networks.

The black, IP30-rated chassis mounts directly onto a DIN rail or a wall. Its fanless design ensures silent operation, with a typical power consumption of 14 W. Administrators can manage the switch via a web interface or a command-line interface, using protocols such as HTTPS, SSH, and SNMPv3. To support high-draw devices, the system provides a total PoE budget of 120 W, with up to 60 W available on individual ports. It also includes integrated DHCP server, snooping, and relay functions to manage IP address assignment across attached devices.
