The base redundant system consists of two hot-plug power supplies in a 1+1 configuration available
at 1400W.

System power supply throttling feature
The PowerEdge C5220 supports a power supply throttling feature that protects the system if power
consumption exceeds the maximum for the supply (1400W). In configurations where power
consumption is greater than the maximum, redundancy is lost, and the PowerEdge C5220 throttles
power consumption of the two or four independent nodes to stay within the power budget.
Performance is degraded in this mode but the system continues to operate. After you replace the
failed power supply, redundancy is restored and all nodes resume normal operation.
