The installation process begins with configuring controller 0 (CT0) first, as it is the primary controller responsible for initial system setup.

The FlashArray//X20R4 requires a minimum AC input voltage of 180V to operate. This ensures stable power delivery for the array's components.

Ensuring Remote Assist is enabled allows Support to perform remote health checks, and updating the case keeps all parties informed for follow-up.

In the FlashArray//XR2 and //XR3 models, the 2-port InfiniBand card should be installed in PCIe slot 2 on controller CT1. This slot is designated for InfiniBand connectivity, ensuring optimal performance and compatibility during the upgrade process. Installing the card in the correct slot is crucial for maintaining proper system functionality and achieving the desired performance metrics.

Cage nuts should be placed in the lowest square hole of the lowest rack unit (RU) where the array rails will be installed to ensure proper alignment and support.
