NIU2A-ES2 Managed Ethernet Switch

The NIU2A-ES2 is a Nano sized, self-contained, Layer 3, managed Ethernet Switch that provides up to 16 ports of 10/100/1000Base-T Gigabit Ethernet ports and four (4) optional 10 Gigabit 850 nm fiber-optic ports. Additionally, there is one Gigabit Ethernet and one RS-232 port for maintenance / configuration interface.


NAI’s rugged, compact Ethernet switches provide big performance in a small footprint. If you need a Gig-E, Layer 2+ switching solution that also provides four channels of RS232/423/422/485 serial communications, consider the RESIU31. It provides 12 ports of 10/100/1000Base-T Layer 2+ Ethernet.


Powered by Broadcom SoCs, both switches are compatible with the following standards:

  • IEEE 802.3ab (1000Base-T Gig-E)
  • IEEE 802.3u (100Base-TX Fast Ethernet)
  • IEEE 802.3i (10Base-T Ethernet)
  • IEEE 802.3x (Flow control/full and half duplex)
