2.2 Gigabit Ethernet Port
The VB9001 comes with five Gigabit Ethernet ports that support high-speed data transmission. Each Gigabit
Ethernet port uses a 8 Position 8 Contact (8P8C) receptacle connector commonly known as RJ-45, which is fully
compliant with IEEE 802.3 (10BASE-T), 802.3u (100BASE-TX), and 802.3ab (1000BASE-T) standards. The pinouts
of the Gigabit Ethernet port are shown below.
