PowerEdge T710 Technical Guidebook20DELL6.6 Maximum Input AmpsThe T710 system exhibits the following maximum current draw at the stated voltages:• 13.7A maximum at 90 VAC• 12.0A maximum at 100 VAC• 10.4A maximum at 115 VAC• 5.75A maximum at 208 VAC• 5.45A maximum at 220 VAC• 5.2A maximum at 230 VAC6.7 EnergySmart EnablementT710 does not support a separate EnergySmart configuration as was offered with certain 10 G servers.A 750 W EnergySmart power supply option is under investigation, but will not be available at RTS.Certain other EnergySmart options may be made available in the future.6.8 Energy Star ComplianceThe final Energy Star specification for servers was issued in mid-May, 2009. Work is underway todetermine which configurations of T710 will be Energy Star compliant. This section will be updatedaccordingly.6.9 AcousticsThe acoustical design of the PowerEdge T710 reflects:• Adherence to Dell’s high sound quality standards. Sound quality is different from sound powerlevel and sound pressure level in that it describes how humans respond to annoyances insound, like whistles, hums, etc. One of the sound quality metrics in the Dell specification isprominence ratio of a tone, and this is listed in the table below.• Office environment acoustics. Compare the values for LpA in Table 7 to see that they are lowerthan ambient noise levels of typical office environments.• Hardware configurations affect system noise levels. Dell’s advanced thermal control providesfor optimized cooling with varying hardware configurations. Some of the perhaps less intuitivebut potentially important decision-making configuration examples are listed below.o Most typical configurations perform as listed in Table 7.o However, some less typical configurations and components can result in higher noiselevels. Examples of acoustical performance for non-typical hardware configurations areshown in Table 7.o The dBA values are not additive, e.g., incorporating a change for 2 dBA reduction andanother change for 3 dBA does not generally produce a 5 dBA reduction.• Noise ramp and descent at Boot-up. Fan speed noise levels ramp during the boot process toadd a layer of protection for component cooling if the system does not boot properly.
