Free Practice Questions for Supermicro SDLCSA Exam

The LPIO (Low-Profile IO) board and BMC cable in Supermicro systems are typically secured by a minimal number of screws for quick serviceability, a principle in DLC designs like the SYS-421GE-TNHR2-LCC. Based on similar systems (e.g., SYS-420GP-TNAR), the metal bracket holding these components is fastened with 2 screws, balancing security and ease of access. Higher counts like 8 (A), 5 (B), or 6 (D) are excessive for a small bracket, while 2 (C) matches Supermicro’s standard for IO-related brackets. In DLC contexts, modularity is key, supporting C as the verified number.

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.
