The fan board in Supermicro systems, including the SYS-421GE-TNHR2-LCC with DLC, manages cooling (even in hybrid air/liquid setups). The removal process, per Supermicro’s service manuals, involves:
Disconnect the power supply from all the fans: This ensures safety and prevents damage, a critical step in DLC systems where fans may supplement liquid cooling.
Pull up on the blue levers on each side of the fan board to unlock it: Blue levers are a common Supermicro design feature for releasing components securely.
Pull the fan board straight up and out of the tray: Once unlocked, the board is lifted free.Option B includes all necessary steps. A skips disconnection and unlocking, C omits the levers, and D misses power disconnection, risking damage. Supermicro’s DLC solutionsemphasize safe maintenance, supporting B as the correct procedure.References:Supermicro motherboard tray service guides, DLC system maintenance protocols.
