This configuration does not supportpower supply redundancy. A power supplyfiller must be installed in bays 1, 2, and 4.2 power supplies The power supplies should be installed inbays 2 and 3 with each supply on separatepower feeds for feed redundancy. Bothpower supplies must be the same type (thatis, the same wattage, ac power supplies, ordc power supplies). A power supply fillermust be installed in bays 1 and 4.4 power supplies Power supplies 1, 2, 3, and 4 must be thesame input type (that is, all ac powersupplies or all dc power supplies).v Four 750-watt -48 volt dc power supplies is the only 750-watt -48 volt dc powersupply configuration that the server supports (for each 4-socket node).v The following table lists the supported ac power supply configurations at both220 V ac and 110 V ac. These configurations apply for each 4-socket node of the8-socket server:Table 30.
