Switch não gerido Digitus DN-651148 Gigabit Ethernet 4+2 portas

The Unmanaged Switch Digitus DN-651148 4+2-Port Gigabit Ethernet is a rugged industrial switch offering four 10/100/1000 BASE-TX RJ45 ports and two 1000Base-Fx SFP ports in an IP40 metal enclosure. Designed for harsh environments, it provides redundant DC power input, non-blocking wire-speed performance and operates across a wide temperature range from -40 °C to 80 °C. The switch is suitable for monitoring, control management and wireless services and supports basic Gigabit Ethernet features for industrial networking.

Advantages

The DN-651148 delivers full-duplex Gigabit connectivity on copper and fiber interfaces, a MAC address table of 2000 entries and a switching capacity that supports wire-speed traffic. Its metal IP40 housing, DIN-rail mounting and redundant 12–48 V DC power input improve reliability in industrial installations. Additional protection against ESD and EFT up to 6 kV helps maintain stable operation in electrically noisy environments.

Suitable for

• IP camera systems and video surveillance networks
• Industrial monitoring and control networks
• Wireless access point backhaul in outdoor cabinets or shelters
• Factory automation segments requiring rugged DIN-rail devices

How to use

Mount the switch on a DIN-rail inside an appropriate enclosure or cabinet. Connect the DC power sources to the redundant 12–48 V inputs, observing correct polarity. Plug Ethernet devices into the RJ45 ports and install compatible SFP modules for fiber connections in the SFP slots. The unmanaged switch operates plug-and-play with no configuration required; devices will negotiate link speed and duplex automatically.

Recommendations

Install the switch in a well-ventilated location within the specified temperature range and use shielded Ethernet cables where ambient electrical interference is present. Ensure SFP modules are matched to the fiber type and transceiver specifications, and provide redundant DC power to increase availability in critical installations.
