Install the 3.5 inch drive adapter into the 3.5 inch hot swappable drive carrier.Power supply unitsPSU specificationsThe power supply unit (PSU) is an internal hardware component which supplies power to the components in the system.Your system supports one of the following:● Two 2400 W, 2000 W, 1600 W, 1100 W, 750 W, or 495 W AC PSUs● Two 750 W Mixed Mode HVDC PSUsNOTE: For more information, see the Technical specifications section.CAUTION: If two PSUs are installed, both the PSUs must have the same type of label. For example,Extended Power Performance (EPP) label. Mixing PSUs from previous generations of PowerEdge servers isnot supported, even if the PSUs have the same power rating. Mixing PSUs will result in mismatch condition orfailure to turn the system on.NOTE: Titanium PSU is nominally rated for 200 V AC to 240 V AC input only.NOTE: When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy or 2+0 – withoutredundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally from both PSUswhen Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs is put into the sleep mode when system utilizationis low in order to maximize efficiency.NOTE: If two PSUs are used, they must be of the same maximum output power.Installing and removing system components 43
