CPU : COM-e Module Ice Lake-D (D-1713NTE) RAM : DDR4 SDRAM (16GB x 2 with ECC (SO-DIMM) DDR4) NOR Flash (Boot) : 64MB NOR Flash (Backup) : 64MB M.2 2280 SSD : 240G NVMe SSD Management : UART RS232 console port(RJ45 x1 port), Out-Band Management Ethernet port(RJ45 x 1 port), In-Band Management Ethernet port 2 x SFP28 ports MAC : Broadcom Tomahawk 5(BCM78902), 1 pcs, 25.6Tbs multi-layer Ethernet switch controller Ethernet Port : 32 x 800G QSFP-DD ports / 32 x 800G OSFP ports Power Supply : 12V/2400W PSU front to back airflow(AC to DC), 1+1 redundant load-sharing, hot-swappable Cooling : 7 FAN-tray modules with 7 pcs of 40mm x 56mm 12V hot-swappable fans DS-SCM Module : Aspeed AST2600 (BMC) + AST1060 (RoT) Dimension : 1U , 438.4mm(W) x 589mm(L) x 43mm(H)

Note:

1. The latest kernel version supported by the Open Network Linux (ONL) upstream is 5.4, and there is no newer kernel version available or maintained at this time. Therefore, this platform is based on kernel 5.4.
2. Some advanced features, such as SDK-based management or advanced switching, require proprietary Broadcom binaries. These binaries are not included in ONL due to licensing restrictions. This commit only ports the platform code and does not include any Broadcom SDK or proprietary binaries.
