##### Electrical and Power Specifications

Use these specifications only as a general planning guide. To determine power values based on expected workloads, use the SPARC T4-1 power calculator located at this online site:

Parameter | Value (at 200 VAC) | Value (at 100 VAC)
--- | --- | ---
Operating input voltage ranges (input voltage tolerance +/- 10%) | 200 to 240 VAC, 50-60 Hz | 100 to 120 VAC, 50/60 Hz
Maximum operating input current (see note) | 3.9 A | 7.87 A
Maximum operating input power (see note) | 762 W | 771 W
Maximum heat dissipation | 2330 BTU/hr2459 KJ/hr | 2239.7 BTU/hr 2556.8 KJ/hr
Maximum standby power | 20 W | 22 W
Maximum server configuration specification under nominal temperature and voltage conditions: One T4 processor, sixteen 32-GByte DDR3 DIMMs, eight HDDs, and six I/O cards. |  |
Idle AC input power | 469 W | 485 W
Peak AC input power (running SpecJBB) | 762 W | 713 W
Minimum server configuration specification under nominal temperature and voltage conditions: One T4 processor, four 4-GByte DDR3 DIMMs, no HDDs, and no I/O cards. |  |
Idle AC input power | 276 W | 280 W
Peak AC input power (running SpecJBB) | 335 W | 358 W

Note - The maximum operating input current values are based on the formula P / (V *0.90), where P = maximum operating input power and V=input voltage. For example: 620W / (100V * 0.90) = 6.89A. You can use this formula to calculate the maximum operating current at your input voltage.
