Two-port RJ45 network selector

The ESTONE OZHW7 is a bi-directional Ethernet switch selector that lets a single device choose between two wired networks or lets one network feed two devices alternately. A single button toggles the active path with physical isolation, so only one link is live at a time. It is built for administrators, developers and home-office users who need to move between separate LAN segments without unplugging cables. The compact aluminium housing measures 4cm by 3.5cm by 2.1cm and draws 3.3 V from a USB source.

Replaces manual cable swapping

Instead of reaching behind a desk to exchange patch cords, the selector provides one-click switching between an internal and an external network or between two workstations sharing one uplink. The jump is worth it when frequent network changes cause wear on ports or when IP conflicts must be avoided by guaranteeing physical separation. It supports Cat5 through Cat8 cabling at up to 1000 Mbps and 2.5G or 5G signalling rates. The device cannot activate both paths simultaneously and cannot power down both ports at once.

Tool-less installation with USB power

Connect the three RJ45 cables, plug the short USB lead into any 3.3 V port and the unit is ready; no drivers or reboot are required. LED indicators show which port is active. The 0.8 metre tether limits placement to within 2.62 ft of the USB source, so verify reach before routing cables. The only common issue is forgetting that both ports cannot be online together, which results in a dead link until the button is pressed again.

Questions about this item

What are the exact dimensions of the OZHW7 switch selector?

The unit measures 4 cm by 3.5 cm by 2.1 cm, which is 5.91 by 4.13 by 1.14 inches, and the attached cable is .8 metres or 2.62 feet long.

How do I install the selector and what is the common mistake to avoid?

Plug the single RJ45 cable into the common port and the two networks or devices into the switched ports, connect the USB power lead to a 3.3 V source, then press the button to select the active path; the mistake is expecting both ports to work at once, which the hardware prevents.

What maintenance or replacement will the OZHW7 need over time?

No scheduled maintenance is required; if the LED status indicator fails or the button becomes unreliable, replace the whole selector as there are no user-serviceable parts inside.
