Context Before
For the modules at the front of chassis - CX-9,BlueField-4, and management - the PDB feeds 12VDC of power to each of the modules. 50VDC l down to 12VDC at the PDB then, via a coper busbar device, the PDB feeds 12VDC to its neighboring modules. The power connector of CX-9 is located near the Paladin HD2 at the top of the modules.
Compute Tray: Mechanical
Evidence
The mechanical components of the VR NVL72 compute tray are slightly more sophisticated than that of the Grace Blackwell. At the front of the chassis, there is a mechanical structure that separates the front into three sections, with the left and right sections housing the Orchid modules and the middle sections housing the BlueField-4, the power delivery and the management modules. Each of the modules will also have a small metal chassis. The mechanical structure provides a simple guiding mechanism that guides the modules to a blind mate process with the midplane and the internal manifolds.
