Installing the drive backplane for NVIDIA GPU configurations
Prerequisites
1. Follow the safety guidelines listed in the Safety instructions.
2. Follow the procedure listed in the Before working inside your system.
3. Remove the drives.
4. Remove the cable cover.
5. Observe and disconnect the intrusion switch bridge cable from the connectors on the storage tray that is connected from
the system board. Observe and disconnect the drive backplane cables, BOSS power and signal cables, fan board cables from
the connector on the storage tray, signal cable from the connectors on the PDB2 and then keep the cables away from the
storage tray. Disconnect the VSB power cables (left and Right) from the connector on the system board and keep them on
the storage tray.
6. Observe and disconnect the drive backplane cables from the backplane and power cables from the system board.
NOTE: To avoid damaging the backplane, remove the disconnected backplane cables from the cable routing clips.
NOTE: Route the cable properly when you replace it to prevent the cable from being pinched or crimped.
Steps
1. Reconnect the backplane cables on the PSB of the bottom layer.
