4.4 Maximum Input Amps

The power supply is equipped with automatic input voltage detection.
Non-redundant power supply:
7.5 - 3.8 A at 100-240 VAC, 50/60 Hz
Redundant power supply:
7 - 3.5 A at 100-240 VAC, 50/60 Hz

4.5 Acoustics

The PowerEdge R410 has balanced acoustic and thermal performance to support a fully-configured
system and meets the Dell Acoustic specification AC0142 Rev. A02 category II-D requirement.
The R410 has an aluminum-base passive heat sink with two embedded heat pipes for the processor
cooling and four 40x56mm dual-rotor fans exhausting air through heat sink and out of the system. In
SKU2 (RDN PSU SKU), there are two extra 40X56mm dual-rotor fans in the front of PDB for redundant
power supply cooling.
The 40x56mm dual-rotor fan has an external PWM speed control, and it is integrated into
motherboard and power distribution unit (PDU). The thermal sensor on the front control board senses
the ambient temperature and adjusts the fan speed accordingly. In a normal office environment, the
fans spin slower, resulting in low acoustics. The fan RPM begins to ramp up with ambient, CPU, IOH,
and DIMM temperatures changes and in different system configurations (e.g., different CPU and RAID
card installation) to meet cooling requirements at higher ambient temperatures.
