A DC-in jack power connector simplifies installation and power management within rackless or desktop deployments.
Advantages
This compact Gigabit Ethernet switch delivers up to 8 ports of 10/100/1000 Mbps connectivity in a black enclosure suitable for visible desktop placement or discreet installation. Support for full duplex operation reduces collisions and improves throughput for simultaneous send/receive traffic. Compliance with IEEE 802.3x flow control helps prevent packet loss during high-traffic conditions. The small footprint and DC-in jack enable flexible placement without requiring specialized power infrastructure.
Suitable for
 Small office and home office wired networks
 Expanding LAN ports for routers or access points
 Connecting desktops, NAS devices and printers
 Temporary network setups for events or testing
Key specifications

How to use
Place the switch on a stable surface with adequate ventilation and connect the power adapter to the DC-in jack. Use standard Cat5e or Cat6 cables to connect network devices to the RJ-45 ports. Connect one port to your router or upstream switch to provide network and internet access to connected devices. The device operates plug-and-play without additional configuration; observe network LED indicators on the ports to confirm link status and activity.
Usage recommendations
For optimal performance, use Cat5e or higher-rated Ethernet cables and connect high-traffic devices such as NAS or servers to individual ports to take advantage of Gigabit speeds. Avoid stacking units directly on top of each other to maintain airflow, and place the switch away from heat sources. Regularly verify link LEDs and test throughput after adding multiple devices to ensure the IEEE 802.3x flow control behaves as expected in your network topology.
