Durable and Reliable Design The DIS-200G Series switches are housed in a highly resistant IP30-rated metal casing to protect them from harsh environmental conditions. The high electromagnetic compatibility (EMC) protects the DIS-200G Series from unwanted effects when operating in environments with strong electromagnetic interference. High Redundancy and Reliability The DIS-200G Series supports ERPS quick 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 device continues to operate in the event of a primary power supply failure. Surveillance Traffic Optimization The DIS-200G Series supports the Auto-Surveillance VLAN (ASV) feature. This automatically detects surveillance devices and puts them into a dedicated surveillance VLAN, segmenting this type of traffic from the rest of the network. Easy Troubleshooting The DIS-200G 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 affected port. Limited Lifetime Warranty D-Link offers a Limited Lifetime Warranty on the DIS-200G Series Gigabit Industrial Unmanaged Switches to further its commitment to product quality and long-term customer confidence.
