GAOTek Industrial 4 x 10/100 M Ethernet Switch

This Industrial 4 x 10/100M Ethernet Switch is a physically isolated industrial Ethernet switch which is designed for usage in hardened industrial environments. It is useful in building an internal network and public network simultaneously.




The GAOTek Industrial 4 x 10/100 M Ethernet Switch is a physically isolated industrial Ethernet switch is designed for hardened industrial environments. It used for building an internal network and public network simultaneously. This Ethernet switch provides for 10/100M Ethernet, one analog video, one RS485 data, and one Gigabit fiber port. It is suitable for occasions with four highly isolated networks and allows DSLAM bandwidth expansion without changing the original fiber optical cable. It offers lightening protection with excellent heat elimination without the need for cooling fans. Additionally, it provides the LED which is used to monitor the working state of each port.


  • 4 10/100Base-TX, 1 analog Video, 1RS485 Data and 1 1000Base-FX uplink port
  • Supports 1536 bytes frame; with 1M bit built-in frame memory
  • Supports 1024 MAC address, with automatic MAC address learning and update functions
  • 4 Ethernet Ports support 10/100M auto-negotiation, Full/Half duplex mode, auto-MDI-MDI-X
  • Automatically selects the Store and Forward mode or Cut-Through mode to reduce the delay
