Power specifications
The following table provides system power consumption/heat load based on the
number of processor books and number of I/O cages with maximum configurations.
Power estimation tool
The Power estimator Tool for z10 BC allows you to enter your precise server
configuration to produce an estimate of power consumption.
Login to Resource Link with any userid. Navigate to Planning, then to Tools, then
to Power Estimation Tools. Specify the quantity for the features that are installed
in your machine. This tool estimates the power consumption for the specified
configuration. The tool does not verify that the specified configuration can be
physically built.
Note: The exact power consumption for your machine will vary. The object of the
Actual power consumption after installation can be confirmed on the HMC System
Activity Display (SAD).

CPC drawer, 0 I/O drawer
CPC drawer, 1 I/O drawer
CPC drawer, 2 I/O drawers
CPC drawer, 3 I/O drawers
CPC drawer, 4 I/O drawers
Notes:
1. Assumes maximum supported configuration (maximum I/O adapters installed)
2. The power factor is approximately unity.
3. Input power (kVA) equals heat output (kW).
4. For heat output expressed in kBTU per hour, multiply table entries by 3.4.
5. Balance:
v Balanced - All phases carry equal current
v Unbalanced-A - Two phases carry equal current and the third phase carries 1.73
times the current in the other two.
v Unbalanced-B - Only one phase pair carries current.
6. See "Dual power installation" on page 101 for recommendations on utility connections
which better balance the current for installations where multiple systems are connected
to the same power panel.
