The Moxa EDS-P206A-4PoE-MM-ST-T is an unmanaged industrial Ethernet switch with integrated Power-over-Ethernet functionality, specifically designed for use in demanding industrial environments. The device combines data transfer and power supply over a single network cable, simplifying the installation and maintenance of end devices such as IP cameras, access points, or other PoE-capable devices. The combination of a robust metal housing, extended temperature range, and integrated protection features makes the switch suitable for use in harsh environments, for example in manufacturing, transportation, or outdoor applications.

Applications

The switch is designed for industrial applications requiring a reliable, low-maintenance network connection. It is particularly suitable for systems operated in control cabinets without active cooling, or for outdoor installations where extreme temperatures and mechanical stress occur. The support for PoE enables power supply to end devices without additional power sources, simplifying installation and increasing flexibility. The multimode fiber ports with ST connectors provide a stable connection over longer distances, ideal for networking distributed systems.

Features and Equipment in Detail

The switch features four 10/100BaseT(X)-PoE ports with RJ45 connectors, which automatically detect transmission speed and connection configuration (MDI/MDI-X). Two additional 100BaseFX-multimode fiber ports with ST connectors enable high-speed connections via fiber optic cables. Each PoE port supports the IEEE 802.3af/at standard and can deliver up to 30 W of power, with a total PoE budget of 120 W. The pinout follows Mode A (pins 1, 2 = V+, pins 3, 6 = V-), ensuring compatibility with common PoE devices.

Technology Explained Simply

The switch operates in store-and-forward mode, where entire data packets are received, checked, and then forwarded, ensuring high data integrity. The packet buffer size of 768 kbit and a MAC address table with 2K entries enable efficient processing and routing of network traffic. Power supply is via a 4-pole removable terminal block and supports an input voltage of 12 to 57 VDC, with redundant power supply possible. The maximum power consumption is 13.2 W (without PoE load). Integrated protection functions against reverse polarity and overcurrent increase the safety and lifespan of the device.

Compatibility and Accessories

The switch is compatible with IEEE 802.3af/at-compliant end devices, such as IP cameras or WLAN access points. The fiber ports are designed for multimode fiber optic cables with ST connectors. Using fiber cables enables a stable connection over longer distances, with the exact range depending on cable quality and wavelength. The PoE function is designed for devices supporting the Endspan mode.

Mounting and Installation

The device is designed for mounting on a DIN rail and can optionally be wall-mounted. The metal housing with IP30 protection rating provides protection against solid objects and splashing water, but not against dust or direct water ingress. Mounting requires no additional tools, and the connection terminals can be easily removed and reinstalled.

Operational Advantages

The extended operating temperature range of -40 to 75 °C allows use in extreme environments without requiring additional cooling. Redundant power supply increases network availability. Integrated protection functions against reverse polarity and overcurrent extend the lifespan and reduce failure risks. The 5-year warranty underscores the product's reliability. The MTBF (Mean Time Between Failures) is 1,289,258 hours according to Telcordia standard, indicating high operational reliability.

Certifications

The device complies with safety standard UL 508, EMI standards CISPR 32 and FCC Part 15B Class A, as well as EMC standards EN 55032/24. EMS certifications according to IEC 61000-4-2 to -4-8 (ESD, RS, EFT, Surge, CS, PFMF) and mechanical tests according to IEC 60068-2-6/-2-27/-2-31 confirm robustness against electromagnetic interference and mechanical stress.

Environmental Conditions

The switch can be operated at a humidity level of 5 to 95 % (non-condensing). The storage temperature is -40 to 85 °C, enabling flexible storage even under extreme conditions.

Dimensions and Weight

The device has dimensions of 50.3 x 114 x 70 mm and weighs 375 g. The compact design allows flexible placement in control cabinets or on the DIN rail.

Manufacturer and Warranty

The switch is manufactured by Moxa and comes with a 5-year warranty. Further information is available at www.moxa.com/warranty.
