Ethernet Switches

Ethernet Switches are broadly categorized into two main categories – Modular and Fixed Configuration.

Modular switches, as the name implies, allows you to add expansion modules into the switches as needed, thereby delivering the best flexibility to address changing networks. Examples of expansion modules are application-specific (such as Firewall, Wireless, or Network Analysis), modules for additional interfaces, power supplies, or cooling fans. Cisco Catalyst 4K and 6K are good examples of Modular switches.

Fixed Configuration switches are switches with a fixed number of ports and are typically not expandable. This category is discussed in further detail below.

According to their complexity and versatility the Fixed configuration switch category is further broken down into:

• Unmanaged Switches
• Smart Switches
• Managed L2 and L3 Switches

By definition, industrial Ethernet switches are designed to withstand harsh industrial environment, such as extreme temperatures, high humidity, large power surge and potential physical impact. These Industrial switches are ideal for infrastructure management, wastertreatment facilities, power utility stations, telecommunication installation, transportation monitoring and other mission-critical applications.
