Technical Specifications

The IP175GHR operates at a voltage of typically 3.3V. It supports IEEE 802.3 and IEEE 802.3u Ethernet standards. The switch controller features a non-blocking architecture, ensuring that all ports can operate at full speed simultaneously. It includes an integrated address lookup table for efficient packet forwarding. The device is typically available in a QFP (Quad Flat Package) for easy surface mounting. It also supports loopback detection to prevent network loops. Furthermore, the switch contains diagnostic LEDs, providing link and activity status information for each port.
