This switch has 27 fiber ports, 4x25G, 20x10G , and 3x100G ports ports. CPU: Intel ® Atom™ Processor C3508,1.6GHz BMC: None MAC: Broadcom BCM88470 (Qumran AX). MISC: Support IEEE1588v2, hot-swappable PSU, hot-swappable fan tray. But notice here, BCM88470 is not supported for SAI now. So the syncd container is not running so far.
