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.
