Description

Dell Fresh Air cooling

With the thermal design and reliability of Dell products, you can have the

capability to operate at excursion-based temperatures beyond the industry

standard of 35°C (95°F) without impacting your availability model. This

solution takes into account servers, networking, storage and other

infrastructure. Find additional information at Dell.com/FreshAir.

Power supply units

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.
