Dell EMC PowerEdge C4140 Installation and Service Manual
Power supply units
Your system supports two 2400 W or 2000 W AC PSUs or two PSUs (one is supported if the optional SATA drive cage is installed)
NOTE For more information, see the PowerEdge
C4140 Technical Specs at
.www.dell.com/poweredgemanuals.
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 is not supported, even if the PSUs have the same power rating. Mixing PSUs will result in mismatch condition or failure to turn the system on.
NOTE When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally from both PSUs when Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs is put into the sleep mode when system utilization is low in order to maximize efficiency.
CAUTION If two PSUs are used, they must be of the same type, and have the same maximum output power.
CAUTION If two PSUs are used, they must operate from the same AC linelevel or the system may report a PSU mismatch.
