Industrial Fiber to Copper 10/100M PoE Media Converter

Overview

(2) VLAN trunking protocol:
There are two types of VLAN trunking protocols:
The N-net NT-IN122 Industrial Ethernet Switch series is 2-Port Industrial Fast Ethernet Redundant Media Converter which supports conversion between single-port 10/100Base-TX and dual-port 100Base-FX. 

ISL (Inter-Switch Link): ISL is a Cisco-specific VLAN trunking protocol.
802.1q (dot1q): 802.1q is standardized and widely used.

The Industrial Fast Ethernet POE Switch designed for critical networks requiring instant auto recovery when redundant mode is selected.

(3) VTP
VTP (Vlan Trunking Protocol) is a VLAN transmission protocol. In a network with multiple switches, you can
Send the VLAN information of the central switch to the subordinate switch.

 While in switch mode, the converters enable the extend transmission distance of network to up to a maximum of 120km via fiber port, and the UTP port is available at either 10M or 100M application,it is packaged in a compact IP40 case that allows either DIN rail or panel mounting for efficient usage of cabinet space. 

The central switch is set to VTP Server, and the lower switch is set to VTP Client.
To be able to learn the VLAN information of the VTP Server, the VTP Client must be in the same VTP domain and require the same password.

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.This Industrial POE Switch is 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, can reduce cables deployment and eliminate the need for dedicated electrical outlets on the wall, ceiling or any unreachable place.
