GL900 • PoE+ Gigabit Ethernet Switch

The GL900 is a 9-port PoE+ capable Gigabit Ethernet switch board, designed for rugged industrial applications. The PCB is provided with 1000BASE-T RJ45 jacks at the front, and in addition a SFP cage at the rear edge for switch expansion. Four front ports are enabled for 802.3at Power-over-Ethernet, up to 120W in total.

The GL900 is equipped with the Marvell® 88E6390 (Peridot) Gigabit Ethernet switch, and in addition the Marvell® Armada® 88F3700 SoC (ARM® v8 Cortex-A53). While the powerful switch is basically self-managed, the CPU enables additional features such as AVB/TSN operation, by means of the optional software stack.
