## Summary description

The Digitus 4 Port Fast Ethernet Network PoE Switch is an unmanaged industrial switch with 4 Fast Ethernet ports and 1 SFP uplink. It supports Power over Ethernet (PoE) and has a switching capacity of 0.1 Gbit/s. Designed for reliable network connectivity in industrial environments, it features a MAC address table with 2000 entries and operates on a DC input voltage of 48 - 57 V.

## Long description

DN-651131 is an industrial 5-port unmanaged Fast Ethernet PoE switch that delivers non-blocking wire-speed performance for harsh environments. It combines four 10/100 Mbps RJ45 PoE ports with one 100 Mbps fibre (SFP) uplink and is designed for reliable data transmission, long service life and compact installation in control cabinets.
Advantages
The switch uses high-quality photoelectric integration modules for stable optical and electrical characteristics and supports full- and half-duplex modes with automatic negotiation. It provides automatic MDI/MDIX port identification, an internal store-and-forward mechanism and support for common Ethernet protocols. The device meets industrial operating standards with an average MTBF exceeding 300,000 hours, wide operating temperature range and surge protection for power lines.
Suitable for
 Industrial Ethernet networks requiring PoE for cameras, access points or sensors
 Compact control cabinets and machine rooms with limited space
 Environments with wide temperature variations (–40 °C to 80 °C)
 Deployments needing an SFP uplink for fibre connection
Key specifications
 Ports: 4 × 10/100 Mbps RJ45 (PoE), 1 × 100 Mbps SFP (fiber uplink)
 Switching capacity: 0.1 Gbit/s
 MAC address table: 2000 entries
 Power input: DC 48–57 V with reverse polarity protection
 Surge protection (power): 5000 A (8/20 µs)
 Operating temperature: -40 °C to 80 °C
 Protection class: IP40
 Colour: Black, Blue; Weight: 0.45 kg
 Standards: IEEE 802.3at (PoE)
How to use
Install the DN-651131 on a DIN rail inside the control cabinet or in a suitable industrial enclosure. Connect the DC 48–57 V power source, observing polarity and ensuring the supply provides required PoE power budget. Connect PoE-capable devices (for example IP cameras or wireless access points) to the RJ45 ports and use the SFP port for a fibre uplink if needed. The switch operates in unmanaged mode — ports negotiate speed and duplex automatically and MDI/MDIX is handled internally.
Usage recommendations
For reliable long-term operation, mount the switch in a ventilated area away from direct heat sources, ensure the power supply meets the device’s voltage range and use surge-protected cabling where lightning or transient surges are a risk.
