unmanaged Gigabit Ethernet Switch

Overview

The switch is developed according to the principle of the bridge. To learn the switch, first understand two concepts:
Conflict domain
The collision domain is the area to which data must be sent.

NT-IN314 unmanaged Gigabit Ethernet Switch series is an industrial-standard 5-port Gigabit switch. It provides 4-port 10/100/1000BASE-TX Ethernet ports and additional one 1000Base-FX fiber port.

The HUB is a non-intelligent signal driver, and there is a need to enter. The entire network of HUB is a conflict domain.
The network under an interface of the switch is a conflict domain, so the switch can isolate the conflict domain.

Rigorous industrial design makes its stability, practicality with basic protection, making it to flexible enough to Ethernet expansion in harsh industrial environments.

Broadcast domain
The area that can be sent to when broadcasting data is a broadcast domain.

NT-IN314 unmanaged Gigabit Ethernet Switch series is packaged in a compact IP40 case that allows either DIN rail or panel mounting for efficient usage of cabinet space.

Switches and hubs are transparent to broadcast frames, so the network formed by switches and HUBs is a broadcast domain.

It provides an integrated power supply with a wide range of voltages for worldwide operation. It also offers dual-redundant, reversible polarity 12V DC to 48V DC power supply inputs for high availability applications requiring dual or backup power inputs.

The network under an interface of the Router is a broadcast domain. So the router can isolate the broadcast domain.

NT-IN314 unmanaged Gigabit Ethernet Switch series complied with IEEE 802.3at High Power over Ethernet technology (optional). It is backward compatible with 802.3af PoE standards to allow users flexibly deploy standard and high powered devices simultaneously with no need of software configuration. With Data and Power over Ethernet from one unit, NT-IN314 unmanaged Gigabit Ethernet Switch series shall reduce cables deployment and eliminate the need for dedicated electrical outlets on the wall, ceiling or any unreachable place.
