The D-Link DIS-300G-12SW Gigabit Industrial Managed Switch is equipped with 8 10/100/1000BASE-T ports and 4 SFP ports. The DGS-300G Series switches feature a robust design making them ideal for deployment in industrial and outdoor surveillance settings, capable of withstanding the harshest environments. The DIS-300G Series furthermore integrate advanced management and security functions to provide a complete solution

• Durable and Reliable Design - The D-Link DIS-300G Series switches are housed in a highly resistant metal casing to protect the switches from harsh environments. The high electromagnetic compatibility (EMC) protects the DIS-300G Series from unwanted electromagnetic interference. Meanwhile, the fanless design extends the life of DIS-300G Series while also being able to operate in a wider temperature range of up to 75 DegreeC. For increased ?exibility, the DIS-300G Series can also be mounted on a DIN rail, wall mounted, or be installed in an equipment rack
• High Redundancy and Reliability - The DIS-300G Series support Fast Ring Failover recovery for ring topologies that ensures minimal downtime and avoids any loss of data in mission-critical deployment settings. Meanwhile, the dual power input allows for a redundant power supply to make sure the network continues to operate in the event of a primary power supply failure
• Easy Troubleshooting - The D-Link DIS-300G Series features loopback detection and cable diagnostics to help network administrators find and solve network problems quickly and easily. Loopback detection is used to detect loops created by a specific port and automatically shuts down the a?ected port. Cable diagnostics helps network administrators quickly examine the quality of the copper cables, recognize the cable type, and detect cable errors
• Easy Management - Easy to manage with user friendly Web-based management and industry-standard CLI
• Gigabit Connectivity with RJ45 and SFP - Designed with 8 x Gigabit ports and 4 x SFPs slot to suit a range of network layouts
• Discrete Size - Small but mighty. To make the most of cabinet space, it measures: 61 x 154 x 109mm
• Fast Deployment - For instant installation it features a snap-to-DIN-rail clip, and also supports wall mounting
• High Availability - Fast Ring failover recovery time of
