To install an adapter into a node, it needs to be powered down. Insert the adapter into a free PCI slot that matches the adapter:
4x, 8x or 16x PCI-Express slot for DXH410 if it is to be used in x4 mode
8x or 16x PCI-Express slot for DXH410 if it is to be used in x8 mode
Make sure you are properly grounded to avoid static discharges that may destroy the hardware. When the card is properly inserted and fixed, close the enclosure and power up the node again. The LED(s) on the adapter slot cover has to light orange.
Proceed this way with all nodes. It is recommended that all nodes are set up identically, thus use the same slot for the adapter (if the node hardware is identical).
You do not yet need to connect the cables at this point: cabling instructions customized for the specific cluster will be created during the software installation which will guide you through the cabling. Generally, the cables can safely be connected and disconnected with the nodes powered up as Dolphin DX is a fully hot-plug capable interconnect.
If you know how to connect the cables, you can do so now. Please be advised to inspect and verify the cabling for correctness as described in the remainder of this chapter, though.
