IS2100D series switch is Yunke China’s new-generation DIN rail industrial switch for the industrial application scenarios with severe operating environment and extremely high demands regarding reliability.  IS2100D series adopts industrial-grade, high-reliability components, industrial- grade hardware structure design and software based on DCNOS platform, can provide various flexible solutions for industrial application scenarios.

High-quality design and robust performance

IS2100D series adopts industrial-grade hardware components and a cooling shell of aluminum alloy to ensure the industrial-grade quality of product.

The series adopts a fan-free thermal design with such multi-cooling structure as built-in cooling fin, thermal grease etc., to ensure an operating temperature range of -40-85°C.

The series is provided with two-circuit direct current power redundancy design and system power failure alarm. It supports resistance to vibration and dust, and follows IP grade protection standards as IP40.

Diverse options of VLAN expansion

The series supports ordinary QinQ, selective QinQ and flexible QinQ technology, which ensures users have the maximum freedom to configure QinQ strategies.

The series supports the exchange function of N: 1 VLAN ID, that is, N: 1 VLAN Translation. N VLAN Tags of access port message can be converted to one designated VLAN Tag, thus providing strong technology guarantee for the convergence of QoS strategies.

The series supports multiple types of VLAN, such as protocol VLAN, MAC VLAN and Voice VLAN, and plays a role in the multi-service integrated network.

Enhanced protection, ensuring safety and controllability

As Ethernet gradually becomes the mainstream access mode in enterprise-level and operator-level networks, clients have increasingly higher demand on the safety, controllability and simplicity of the access layer. IS2100D series is provided with various safety protection mechanisms, offering various anti-DOS attack technologies like SYN Flood, Land and IGMP Flood, and supporting BPDU Guard and Root Guard, prevents accidental topology rings and illegal edge devices from becoming root nodes, thus avoiding unnecessary topological shock.

In terms of anti-attack measures targeted at user level, the series simultaneously supports DHCP snooping and IP Source Guard based on port and VLAN respectively, which can be combined to effectively prevent the illegal address spoofing of MAC, IP and MAC+IP and reduce the risk of DOS attack.

The series supports source MAC address learning restriction function based on port and based on VLAN, and effectively prevents source MAC spoofing from impacting the device MAC table entry, which results in, among others, flooding due to normal users’ failure to learn MAC table. 

The series supports customized ACL, and can perform more flexible rule matching on the first 128 bytes of message’s Ethernet header or IP header according to user demands. 

The series supports standard 802.1X authentication access, expanded 802.1X authentication access, effectively avoids IP conflict and PC cloning, and realizes extended enhancement functions like static IP address issuing.  

Redundant backup, guaranteeing stability and reliability

The series has two gigabit uplink ports, which realizes dual uplink network and enhances the robustness and high reliability of user network structure.

The series is the first to support the industrial standard ERPS ring network solution, supports various networking mode like single ring, tangent ring, intersecting ring and dual homing ring, ensures the convergence speed to be less than 50ms, and realizes carrier-grade reliability. 

The series supports multi-process MSTP. The processes can run different spanning tree protocols. At the meantime, the number of access sub-rings is increased. Additional access rings can be realized by creating a new MSTP, without affecting original service traffic to reduce network impact.

The series supports DCN EMVTE enhanced multi-VLAN sub-network traffic engineering technology, which is DCN’s link backup and load balancing solution based on multi-VLAN sub-network for dual uplink networking environment. Through ULPP (Uplink Protection Protocol) and ULSM (Uplink State Monitor) protocols, fast switch convergence of multiple uplinks is realized to guarantee network performance.

The series has built-in lightning protection settings. The service port has 8KV lightning protection capacity to effectively withstand lightning. This makes the series more adaptable to harsh environment than ordinary switches, and significantly reduces the damage rate of device.

The series provides dual DC power input and system power failure alarm.

PoE+ Supply, smart power supply

PoE model supports enhanced Ethernet power supply function (PoE+), with maximum 30W output power per port, and can directly power auxiliary PD devices (including 802.11n wireless access point, visual IP phone, HD web camera, etc.).

The series provides a perfect PoE solution, which allows users to selectively set PoE power supply port and configure the maximum output power for each port, so as to save energy. The series supports setting for various power supply strategies, such as free setting the power supply priority for ports. Thus when there are a large number of devices to be powered, it can maximally ensure that devices with high priority are powered first. Thus, flexible PoE power supply management is realized.
