Slot Selection Rules for Onyx2 Deskside Systems
Each Onyx2 node board accommodates a maximum of 3 TPU cards. The Onyx2 deskside
system has 6 XIO slots. Slots 3, 5, and 6 (shown in Figure 3) are available for TPU XIO
boards. It is recommended that you fill available odd-numbered slots before filling
even-numbered ones, and that you fill lower-numbered slots before higher-numbered
ones. For example, fill slot 3 before filling either slot 5 or slot 6.
Note: Do not use Onyx2 XIO slots 2 or 4 for the XIO TPU card.
