Product Description


The N-net NT-IN321-2 is an Industrial Gigabit Ethernet Switch with 2Fiber port and 1RJ45 port, with fiber redundancy can be applied to the far edges of your network. This Industrial Gigabit Ethernet Switch also offers dual 12~48 VDC power inputs redundan, if one power input fails, the switch can automatically falls over to the second power input. With IP40 protection, you can use it in cold, scorching heat, dirty, outdoor environments with temperature extremes of -40° to +85°C.


1. Dual fiber port redundancy available with DIP switch

2. Built-in efficient switching core to implement flow control and reduce broadcast packets

3. Protocol supported: IEE802.3 10Base-T, IEEE802.3u 100Base-TX/FX, IEEE802.3ab 1000Base-T, IEEE802.3z

5. 10/100/1000Base-TX can automatically identify the direct line and cross-line, is compatible with various cards, switches, HUB and other Ethernet devices

6. Take store-and-forward mechanism to avoid packet loss and error frames

7. This Industrial Switch Provide four independent 10M/100Mbps/1000Mbps self-adaptive twisted pair ports; realize Ethernet port redundancy and multiple users access.

8. Support up to 1536 bytes packet.

9. This Industrial Fiber Switch Support full-duplex flow control / half-duplex back pressure mode

10. 12V--48V DC or 24V AC power supply input, redundant power and reverse polarity protection

11. -40 to 80℃ operating temperature to meet a variety of complex environment

12. IP40 standard protection housing.

13. This Industrial Ethernet Switch Supports ESD protection at Ethernet port and EFT protection.

14. Easy installation, DIN rail or panel mountable.

15. Dual fiber multi mode, single mode and WDM single mode fiber compatible.

16. Support POE power supply up to 25.5W (optional)

17. 12 Gbps back plane bandwidth, 1 k MAC address automatic learning and 512kb internal cache for data buffer
