Features
The NSM-208PSE is an 8-port unmanaged PoE (Power over Ethernet) Industrial Ethernet switch. It supports 8 PoE ports which are classified as power source equipments (PSE). The NSM-208PSE makes centralized power supply come true and
provide up to 15.4 watts of power per port. The NSM-
208PSE can be used to power IEEE802.3af compliant powered devices (PD) by Ethernet cable and eliminates the need for additional power wiring.
- Automatic MDI/MDI-X crossover for plug-and-play
- Each port supports both 10/100Mbps speed auto negotiation
- Store-and-forward architecture
- Full duplex IEEE 802.3x and half duplex backpressure flow control
- 8 PoE ports with Power Sourcing Equipment (PSE) operation
- Auto-detection of PD (powered devices) and automatic power management
- Over-temperature, over-current and over/under-voltage detection
- Supports operating temperatures from -40°C ~ +75°C
- DIN-Rail mount
- NSM-208PSE-R meets railway standards. "-R" stands for products with MIL SPEC conformal coating protection
