What This Bolster Assembly Does
The 2299804-1 is a bolster assembly — a stainless steel frame that backs the LGA 3647 socket on the motherboard, distributing the compressive load from the heatsink or retention mechanism evenly across the socket body. It ships with a cover that protects the socket area during handling and board assembly; the cover stays on until the CPU is installed. The body material is stainless steel, chosen for stiffness and corrosion resistance in server and datacenter environments where the assembly sees repeated thermal cycling.
