Design typically involves five core stages: Requirement Analysis, Site Selection & Space Planning, Architecture Design (e.g., Leaf-Spine), Equipment Selection (Core/Aggregation switches), and Implementation & Testing.

A TR is an enclosed space in a building used to house network equipment like switches and patch panels. It serves as the junction between vertical backbone cabling and horizontal cabling to end-user areas.

Consider four key factors: Environmental conditions (temp range/IP rating), Port requirements (RJ45/SFP/PoE), Mounting style (DIN-Rail/Rack-mount), and Management type (Unmanaged/Managed).

Industrial switches feature fanless cooling, rugged casings, and high EMI resistance. They support extreme temperatures and offer fast ring redundancy with dual DC power inputs, whereas commercial switches are designed for climate-controlled environments.

Unmanaged switches are low-cost and plug-and-play, ideal for simple setups. Managed switches support data monitoring, VLANs, and security, essential for large enterprises.

PoE allows a single cable to provide both data and power. The main advantage is reduced cabling costs for devices like cameras and APs in locations without power outlets.

They allow for long-distance transmission (kilometers vs. 100m for copper) and offer immunity to electromagnetic interference, which is critical in industrial settings.
