Hallitsematon kytkin Digitus DN-95347-2 16-porttinen Gigabit Ethernet 1U

The Digitus DN-95347-2 is an unmanaged 16-port Gigabit Ethernet switch in a 1U rack-mount design that supports Power over Ethernet (PoE) with a total PoE budget of 250 W. It provides wire-speed forwarding, 2 uplink ports and a switching capacity of 36 Gbit/s, making it suitable for expanding network connectivity in small to medium-sized business environments.

Advantages

The switch supports IEEE 802.3af/at PoE standards and delivers up to 30 W per port, with automatic detection and intelligent identification of PoE-powered devices to avoid damage to non-standard devices. It features port power-supply prioritization to maintain power to critical nodes, panel indicators for status monitoring and fault analysis, VLAN support, flow control for full-duplex and back-pressure for half-duplex operation, and Energy-Efficient Ethernet (IEEE 802.3az) to reduce power consumption.

Suitable for

• Connecting and powering IP cameras and CCTV systems
• Supplying PoE access points in small to medium enterprise networks
• Network expansion in rack-mounted installations (1U)
• Deployments requiring unmanaged, plug-and-play switching

How to use

Mount the DN-95347-2 in a standard 19-inch rack (1U) and connect the AC power cable to an appropriate mains outlet (AC 100–240 V, 50/60 Hz). Connect network devices to the Gigabit RJ-45 ports; PoE-capable devices will be automatically detected and supplied with up to 30 W per port until the 250 W total budget is reached. Use the panel indicators to verify link/activity and PoE status. For unmanaged operation no configuration is required; connect uplink ports to the rest of the network as needed.

Recommendations

To ensure stable PoE operation, calculate the total power draw of connected devices before deployment and prioritize critical devices using the switch’s port power-supply prioritization. Install the switch in a ventilated rack space, maintain ambient temperatures within the specified range, and ensure proper grounding of the rack installation.
