NOTE:
If a system with 1100 W AC or HVDC PSU operates from 100 to 120V, the power rating per PSU is derated to 1050
W.
NOTE:
If a system with 1600 W PSUs operates from 100 to 120 V, then the power rating per PSU is derated to 800 W.
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
230 V.
NOTE:
PSUs rated for 1600 W and higher require high-line voltage (200-240 V) to supply their rated capacity.
System battery specifications
The PowerEdge R640 system supports CR 2032 lithium coin cell system battery.
Expansion bus specifications
The PowerEdge R640 system supports PCI express (PCIe) generation 3 expansion cards, which are installed on the system, using
expansion card risers. This system supports 1A, 2A, 1B, and 2B expansion card risers.
NOTE:
• The expansion card riser slots are not hot-pluggable.
• Internal cable connectors are not hot-pluggable.
