Connect monitors to the onboard HDMI port or to the Thunderbolt/USB-C ports as supported by your host. Attach USB peripherals, an Ethernet cable, SD cards, and RCA audio cables as needed. The dock will provide power to the connected laptop (up to 100W) and supply up to 15W on downstream Thunderbolt ports and up to 7.5W on each USB port for bus-powered devices.

Usage recommendations

For best network performance use Cat5e or higher cabling and a 2.5Gb Ethernet-capable switch or NAS. Choose an M.2 NVMe SSD that is listed as compatible in Sonnet’s NVMe SSD compatibility documentation. When using multiple high-bandwidth devices and displays, verify your computer’s Thunderbolt/USB4 video and bandwidth capabilities to ensure the desired multi-display and throughput configuration.
