Overview
The WESTERMO SDW-550 is a rugged, unmanaged 5-port Industrial Ethernet switch designed for industrial, transportation, and marine applications. Its plug-and-play nature eliminates configuration complexity, making it ideal for field device networks, decentralized systems, and situations requiring simple, reliable connectivity.
The SDW-550 features dual redundant power inputs and total galvanic isolation between ports and chassis, protecting against ground loops, surges, and electrical noise. While the SDW-550 is considered a legacy model, the SDW-550-T5G is the recommended replacement, offering Gigabit speeds and extended temperature tolerance.

FAQ
Q1: Why choose the SDW-550 over a managed switch?
A1: It offers simplicity, cost-effectiveness, and minimal maintenance. Ideal for small clusters or network edges where advanced features like VLANs, QoS, or SNMP are unnecessary.
Q2: What is the difference between SDW-550 and SDW-550-T5G?
A2: The T5G supports Gigabit Ethernet (10/100/1000 Mbps), wider temperature range (down to -40°C), and is the recommended current replacement for legacy SDW-550 systems.
Q3: What does IP21 protection mean?
A3: The switch is protected against finger contact (IP2X) and vertically falling water drops (IPX1), suitable for mounting in enclosures with minor moisture or condensation.
