This manual describes how to replace customer-replaceable units (CRUs) in the NVIDIA DGX Vera Rubin NVL72 system.

Customer-Replaceable Units

You can replace the following components:

• E1.S NVMe cache drive

• Compute tray battery

• NVLink Switch tray battery

• Power supply unit (PSU)

• Power shelf management module

An authorized NVIDIA representative must replace components that aren’t on this list.

Recommended Tools

The following tools are recommended for the procedures in this manual:

• Screwdrivers, including a Torx T6 screwdriver
