What are the full steps and proper order for removing the LPIO board from the...

Removing the LPIO (Low-Profile IO) board from the PCIe tray in the SYS-421GE-TNHR2-LCCinvolves:

Remove PCIe air shroud: Clears access to components (standard in Supermicro designs).

Remove all AOC NIC cards: Disconnects cards on the LPIO board for unobstructed removal.

Remove metal bracket holding down LPIO board: Unscrews (typically 2 screws) the bracket securing the board.Option B follows Supermicro’s logical service order (e.g., SYS-420GP-TNAR), ensuring safe access in DLC systems. A (GPU) is unrelated, C (tray removals) is excessive, and D (fans) is irrelevant. B aligns with Supermicro’s DLC modularity, making it correct.References:Supermicro PCIe tray service guides, DLC system IO removal protocols.
