* Six (6) x 25G Base-R SFP28 interfaces
* One (1) x RJ-45 console connector, interfacing to the on board UART
* One (1) x USB Type-A connector, interfacing to the USB 2.0 port (0)
* One (1) x USB Type-mini B connector, interfacing to the USB 2.0 port (1)
* One (1) x RJ-45 1G Base-T Management port, interfacing to the host
  port (shared with PCIe) Connected to 88E1512 Gigabit Ethernet Phy
* One (1) x Oculink port, interfacing to the PCIe port for external CPU
  connection
* POE 802.3AT support on Port 1 ~ Port 32, 802.3BT support on Port 33 ~
  Port 48 (Microsemi PD69208T4, PD69208M or TI TPS2388,TPS23881
  solution)
* POE total power budget 780W
* LED interfaces per network port/POE
* LED interfaces (common) showing system status
* PTP TC mode Supported (Reserved M.2 connector to support BC mode)
