D-Link DIS-300G-8PSW Industrial Gigabit Managed PoE Switch with SFP

Applications

Highlights

• 4x PoE ports per IEEE 802.3af/at with up to 30 W per port, plus 2 additional copper ports and 2x SFP slots — 8 ports in total
• 120 W total PoE budget for running multiple devices simultaneously, such as cameras or access points
• Network redundancy with recovery times under 20 ms across ring, coupling, and dual-homing topologies as well as chain connections
• Extended operating temperature range of -40°C to +75°C, including cold-start-capable operation
• IP30-rated housing for DIN-rail or wall mounting, measuring 77 x 154 x 128 mm

Technical Overview

The switch supports Spanning Tree protocols per IEEE 802.1D/802.1w/802.1s and link aggregation per 802.3ad. Network segmentation is handled through up to 256 static VLAN groups (1024 including dynamic groups) with port-, MAC-, IP-subnet-, and protocol-based assignment plus 802.1ad Q-in-Q tagging, complemented by IGMP multicast management (v1/v2/v3) for up to 255 groups. Quality of Service per IEEE 802.1p with eight priority queues per port keeps prioritized traffic flowing, for instance video streams from PoE cameras.

Security features include 802.1X authentication, IP- and MAC-based access control, and storm control; authentication can run locally or through RADIUS/TACACS+ (AAA). Management is available via CLI, web interface, SNMP v1/v2c/v3, Telnet, or encrypted HTTPS/SSH, complemented by syslog, port mirroring, copper diagnostics, and SFP modules with Digital Diagnostic Monitoring (DDM). The redundant power supply covers an input voltage range of 12 to 58 V DC depending on the PoE mode in use.

Notes

Matching SFP transceivers (DIS-S301SX, DIS-S302SX, DIS-S310LX) and external power supplies are compatible accessories. D-Link provides a 5-year manufacturer warranty on the DIS-300G-8PSW.
