GLYPH<SM590000> Two DC converter assemblies (DCAs) that provide power to the CPC drawer. The loss of  one DCA leaves enough power to satisfy the drawer’s power requirements (n+1  redundancy). The DCAs can be concurrently removed and replaced (one at a time). GLYPH<SM590000> Water-cooling manifold for PU chips. GLYPH<SM590000> Three SMP connectors for inter-drawer connectivity. Figure 2-6 shows the front view of a CPC drawer, with fanouts slots and connector for water  cooling, and the rear view of drawer, with the DIMM slots and DCA connector. Figure 2-7 shows the front view of a fully populated processor drawer. Redundant FSP  adapters (2) always are installed, and PCIe I/O fanouts are plugged in specific slots for best  performance and availability. SMP interconnect cables are present when multiple drawers are  present. Also present are the ICA SR and InfiniBand fanouts for coupling connectivity.
