NOTE: Heat dissipation is calculated using the PSU wattage rating.
NOTE: This system is also designed to connect to the IT power systems with a phase to phase voltage not exceeding 240 V.
NOTE: PSUs rated for 1100 W Mixed Mode HVDC or 1100 W AC and higher require high-line voltage (200–240 V AC) to supply their rated capacity.
Expansion card installation guidelines
NOTE: A System Event Log (SEL) event is logged if an expansion card riser is not supported or missing. It does not prevent your system from turning on. However, if a F1/F2 pause occurs and an error message is displayed.
The PowerEdge R740 system supports up to eight PCI express (PCIe) generation 3 expansion cards, that can be installed on the system board using expansion card risers. The following table provides detailed information about the expansion card riser specifications:
