DIS‑300G‑14PSW managed the switch, equipped with 10 10/100 / 1000Base-T ports (8 ports support Power over Ethernet (PoE)), and 4 1000Base-X SFP ports used to connect to a high-speed backbone, is designed for applications in the networks of industrial enterprises. The DIS‑300G‑14PSW supports D-Link Green technology and advanced management and security features. Management functions include SNMP, Web-based management, D-Link Network Assistant and the command-line interface (CLI).
The metal case (IP30 standard) and a wide operating temperature range allow the DIS‑300G‑14PSW to be used in adverse environmental conditions. A high level of electromagnetic compatibility ensures the stability of the switch to the effects of strong electromagnetic interference, and the passive cooling system - the noiseless operation of the switch. This device can be mounted on a wall, mounted on a DIN rail or in a 19-inch rack using the appropriate brackets (rack mounts are not included in the scope of delivery).
Protection against static electricity of 6 kV ensures the stability of copper ports to the induced voltage and prevents damage to the switch and the devices connected to it.
Reliability and fault tolerance
The DIS‑300G‑14PSW supports Ethernet Ring Protection Switching (ERPS, ITU-T G.8032), which provides minimum recovery time for the ring after a failure. To ensure maximum resiliency in the switch, a dual redundancy scheme is implemented: up to two independent DC power supplies can be connected to the DIS‑300G‑14PSW.
Auto Surveillance VLAN
The DIS‑300G‑14PSW supports Auto Surveillance VLAN (ASV), which makes it an ideal solution for deploying video surveillance systems. This functionality allows you to automatically recognize in the general network of video surveillance equipment and allocate it to a separate VLAN within which the highest priority of service will be assigned for video traffic. Support for Auto Surveillance VLAN ensures stable operation of video applications, high-quality transmission and maximum protection of multimedia traffic, regardless of the overall network load.
The DIS‑300G‑14PSW supports cable diagnostics and Loopback Detection, which allows network administrators to quickly and easily find and fix network problems. Loopback Detection is used to detect loops and automatically turn off the port on which the loop is detected. The cable diagnosis function is used to determine the status of the twisted pair, as well as the type of cable fault.
Power over Ethernet
The 8 ports of this switch support the IEEE 802.3at PoE standard. At the same time, the total budget of the switch can reach 240 W depending on the power of the connected power source. If you connect a more powerful power source such as 300 watts, the PoE budget can reach 240 watts, that is, 30 watts per port. The special indicators on the front panel of the device helps control the activated PoE budget.
Quality of Service
The DIS‑300G‑14PSW implements a rich set of multilayer QoS/CoS features to ensure that critical network services such as VoIP, video conferencing, IPTV, and IP surveillance are given high priority. Flexible packet classification can be based on various header fields or user-defined packet content to help administrators prioritize network traffic. Traffic shaping features guarantee bandwidth for these critical services when the network is busy. Multilayer QoS/CoS features let IT managers arrange network resources more efficiently in enterprise environments.
