Industrial poe switch

Types of industrial poe switches

An industrial PoE switch is a network switch that is manufactured for use in industrial settings. It is specifically designed to withstand harsh environmental conditions, temperature fluctuations, and other challenges typical of industrial environments. Different types of industrial PoE switches include the following:

• Managed PoE switches: These switches are usually equipped with advanced features and configuration options that allow network administrators to have better control over the network. Some of the features commonly found in managed PoE switches include VLAN support, Quality of Service (QoS) configuration, port mirroring, and SNMP monitoring. Managed PoE switches are ideal for large industrial networks that require extensive configuration and monitoring.

• Unmanaged PoE switches: Unmanaged PoE switches are typically plug-and-play devices that do not require any configuration. They are designed for simple industrial networks that do not need advanced features or remote management. Unmanaged PoE switches are easy to install and use, making them suitable for small to medium-sized industrial applications.

• L2 Managed PoE switches: L2 managed PoE switches offer Layer 2 switching capabilities, allowing them to forward data packets between devices on the same network. These switches support VLANs, which help in segmenting the network and improving performance and security. L2 managed PoE switches may also support link aggregation, which involves combining multiple Ethernet links to create a single high-bandwidth connection.

• L3 Managed PoE switches: L3 managed PoE switches offer more advanced features compared to L2 managed PoE switches. In addition to the Layer 2 switching capabilities, L3 managed PoE switches provide routing functionality at Layer 3 of the OSI model. This allows them to route data packets between different networks based on IP addresses. Consequently, L3 managed PoE switches help in creating multiple IP subnets and implementing inter-VLAN routing.

• Light Layer 3 managed PoE switches: Light Layer 3 managed PoE switches are a type of Layer 3 switch that offers basic routing functionality. They typically support static routing, which allows manual configuration of routes between different IP subnets. Light Layer 3 managed PoE switches are suitable for industrial networks that require simple inter-VLAN routing without the need for advanced dynamic routing protocols like OSPF or RIP.

Industrial Ethernet switches include features like RSTP and MSTP to provide network redundancy and rapid failover in case of link or device failures. Some of the switches may also support features like ERPS and G.8032 for ring network topologies.

• Security:

These switches also come with port security features, such as MAC address filtering and 802.1X authentication. They also support network access control (NAC) solutions to ensure only authorized devices and users can connect to the network. Some switches may also include features like IPsec and SSL VPN support for secure remote access.

• Management:

These switches also offer various management options, such as command-line interface (CLI), web-based management, and SNMP support for monitoring and configuring the switch remotely. They also support features like firmware upgrades, configuration backup and restoration, and syslog for logging and troubleshooting purposes.

• Environmental Hardening:

Industrial Ethernet switches are designed to withstand harsh environmental conditions like extreme temperatures, humidity, and vibration. They often have ruggedized enclosures and are certified to meet industry standards for environmental hardening, such as IP67 and NEMA.

• Power Input Options:

These switches offer flexible power input options to suit different deployment scenarios. They may support wide voltage DC power input, such as 12V, 24V, 48V, or even 110V DC. Some switches also support dual power input for redundant power supply.

How to Choose an Industrial PoE Switch

When choosing an industrial PoE switch, it is important to consider many things, such as the number of connected devices, the power requirements of end devices, required network speed, and environmental factors.

• Power budget: It is essential to calculate the power budget. This will help to determine the number of end devices that can be powered simultaneously. It is also wise to consider the power redundancy option that can be used to ensure uninterrupted power supply in important applications.

• Port density and speed: The number of PoE ports required should be put into consideration. Also, consider the data transfer speed required by the application.

• Managed vs. unmanaged: The choice between a managed switch and an unmanaged switch should be made. An unmanaged switch is plug-and-play. It requires no configuration. It is ideal for small-scale deployments. However, a managed switch offers more control and configuration options. It can provide useful features for network optimization and troubleshooting.

• Environmental factors: The temperature range of the operating environment should be taken into consideration. Choose a switch that can withstand the temperature and humidity conditions of the deployment environment.

• Mounting options: The mounting options available should be considered. If there is limited space available, a DIN-rail mount switch is often a more suitable option. Also, ensure to check the dimensions of the switch to make sure it fits in the available space.

• Reliability and fault tolerance: Consider the reliability and fault tolerance features of the switch. It is ideal to choose a switch that offers redundancy features such as STP (Spanning Tree Protocol) to ensure network uptime.

• Choose a switch with the right PoE standard. Some devices, like IP cameras, may use high power, but others, like IP phones, may not. It is essential to know which PoE standard is required by the end devices to be connected.

• Consider the type of PoE required. This is because there are different types of PoE, and each has different power requirements. For example, PoE+ can provide up to 30 watts of power per port, while PoE++ can provide up to 60 watts.
