Supermicro SDLCSA - Supermicro Direct Liquid Cooling Service Associate (SDLCSA) Exam

An AOC (Add-On Card) in Supermicro systems, such as a NIC or GPU card, is secured to its bracket with1 screwon the metal bar at the top, a standard PCIe card mounting practice (e.g., SYS-420GP-TNAR manuals). This single screw ensures stability while allowing easy removal, consistent with Supermicro’s DLC system serviceability. 4 (A), 2 (B), or 3 (D) screws would be excessive for a single card bracket. Supermicro’s modular design in DLC solutions supports C as the verified number.References:Supermicro AOC card installation guides, DLC system component specs.

In Supermicro’s high-end systems like the SYS-421GE-TNHR2-LCC, the PCIe tray, often loaded with multiple GPUs (e.g., 8 NVIDIA HGX GPUs in DLC setups), is heavy and complex. Supermicro’s safety guidelines (e.g., SYS-420GP-TNAR Manual) recommend two people for removing such trays due to weight (over 50 lbs with GPUs) and the need to avoid damaging liquid cooling lines or connectors. In DLC systems, the tray integrates with coolant manifolds, adding to its bulk. Thus, True (A) aligns with Supermicro’s expertise in ensuring safe handling of DLC components.References:Supermicro safety instructions, DLC rack-scale system specs.
