Ethernet network splitter switch ALLNET ALL-NS1003 3-port 1GbE

The ALLNET ALL-NS1003 3-port 1GbE Ethernet splitter switch is a compact unmanaged switch that provides three Gigabit Ethernet ports for basic wired networking. Designed for small offices, home networks and simple network expansions, it enables multiple devices to share a single uplink with plug-and-play operation. The unit supports standard Ethernet connectivity at 1 Gbps per port and requires no configuration, making it suitable for situations where straightforward wired links are needed between desktops, printers, IP cameras or networked appliances.

Advantages

The switch offers Gigabit-speed ports in a small, low-profile enclosure that can be placed on a desk or mounted in constrained spaces. Unmanaged operation eliminates the need for configuration or management software, while auto-negotiation and auto-MDI/MDIX simplify cable and device compatibility. The device provides a simple way to expand port count from a single uplink without additional network complexity, and its energy-efficient design helps reduce power consumption during normal operation.

Suitable for

• Small office desktop networking and peripheral connections
• Home networks requiring additional wired Gigabit ports
• Connecting printers, NAS devices or IP cameras to an existing router or modem
• Temporary or portable network setups for meetings or events

Key specifications

• Ports: 3 × 10/100/1000 Mbps Ethernet ports
• Operating mode: Unmanaged switch with plug-and-play functionality
• Auto-negotiation: Supported on all ports
• Auto MDI/MDIX: Supported, no crossover cable required
• Throughput: Designed for line-rate forwarding at Gigabit speeds for typical small network use
• Form factor: Compact, desktop-mountable housing
• Power: External power adapter (included) with low-power operation

How to use

Place the switch on a stable surface near your router or network uplink. Connect the uplink from your router or modem to one of the switch ports using a standard Ethernet cable, then connect your devices (PCs, printers, NAS, IP cameras) to the remaining ports. Plug in the external power adapter and verify that the link/activity LEDs indicate established connections. As an unmanaged device, the switch requires no software installation or setup; devices connected through the switch will obtain network access according to your existing network configuration.

Usage recommendations

For reliable performance, use Category 5e or higher Ethernet cables when connecting Gigabit devices. Place the switch in a ventilated location away from sources of heat and moisture. If connecting multiple high-bandwidth devices simultaneously, monitor device performance at the network level to ensure the single uplink meets aggregated bandwidth needs.
