The GSW140 is a highly integrated, low-power, non-blocking six-port Gigabit Ethernet QoS Switch with four Ethernet PHY, one 1G/2.5G SGMII+ and one management port. The GSW140 complies with 10BASE-TE, 100BASE-TX and 1000BASE-T standards. Support of Energy-Efficient Ethernet 802.3az reduces power consumption further in idle state. Smart LED brightness control logic is integrated for additional power saving. LED brightness can be adjusted either by an external push button or varies dynamically depending on the intensity of the light with an external light sensor.
The GSW140 devices are configurable via pin-strapping, by means of the MDIO interface, UART interface, SPI interface or optionally by connecting an external EEPROM. Integrated QoS technology prioritizes switch traffic for different classes of applications e.g. VoIP, video, audio and data based on port ID, 802.1p, IP DSCP/ToS and multiple fields of the packet. IEEE 1588v2 support enables highly accurate precision timing protocol applications. The 1 M Bits embedded packet storage SRAM is integrated with 9 KB jumbo frame support.
The GSW140 features 4K entry VLAN table for 802.1Q VLAN operation and double VLAN tagging (Q-in-Q) translation. The GSW140 supports
IGMPv1/v2/v3 and MLD v1/v2 snooping for efficient use of network bandwidth.
