D-Link DIS-300G-8PSW Industrial Gigabit Managed PoE Switch
PRODUCT DESCRIPTION
D-Link DIS-300G-8PSW Industrial Gigabit Managed PoE Switch with SFP Slots (DIS-300G-8PSW) - 5 Years Local Warranty
Hardened PoE Switching for Harsh Sites
The D-Link DIS-300G-8PSW is an industrial Gigabit managed switch with 4 x 10/100/1000BASE-T PoE ports, 2 x 10/100/1000BASE-T ports and 2 x 100/1000BASE SFP slots. The PoE ports support IEEE 802.3af and 802.3at with a 120 W total budget for IP cameras, wireless access points and sensors in the field.
Built to Survive Heat, Cold and Vibration
A fanless IP30 housing operates from -40 to +75 °C and is tested for vibration (IEC 60068-2-6), shock (IEC 60068-2-27) and free fall (IEC 60068-2-32), with NEMA-TS2 certification for traffic-control cabinets. It mounts on a DIN rail or a wall.
High Availability
Redundant DC input terminals with reverse power protection, an alarm relay output, STP/RSTP/MSTP and D-Link's fast failover protection ring (link loss recovery under 20 ms) keep critical links running.
Familiar Management
Configure it through an industrial CLI, web GUI, SNMP v1/v2c/v3 or Telnet, with PoE scheduling, power control and PD power consumption monitoring.

Compatibility & Software Support
Management
Industrial CLI, web-based management, SNMP v1/v2c/v3 and Telnet. D-Link's software feature groups: bridge, VLANs and protocols; multicast; traffic management and QoS; security; and network redundancy (IEEE 802.1D STP, 802.1w RSTP, 802.1s MSTP and fast failover protection rings with link loss recovery under 20 ms).
Optional Accessories (per D-Link)
D-Link industrial DIN-rail power supplies DIS-H30-24, DIS-H60-24, DIS-N240-48 and DIS-N480-48; industrial SFP modules DIS-S301SX, DIS-S302SX and DIS-S310LX. The switch is DC-powered, so an industrial PSU is needed on AC sites.
Typical Use
Roadside and traffic cabinets, factories, utilities and outdoor enclosures powering PoE cameras and APs with a fibre uplink.
