6.5.1 Configuring PUE Standard Mode

Procedure
Step 1 Log in to the ECC800 WebUI as an administrator.
Step 2 Choose System Settings > PUE Configuration.
Step 3 Set PUE function to Enable.
Step 4 Set the PUE configuration mode to Standard, and click Submit.
Step 5 View the PUE. Choose Query > Performance Data and set Device to ECC800 from the
drop-down list box. For other searching criteria such as Performance data, Statistics mode,

Example of PUE Calculation
In this example, the PUE is calculated on the basis of the start time 17:00 and end time 18:00.
1.
2.
Issue 07 (2020-03-16)
The PUE ranges from 1 to 3. If the PUE value is greater than or equal to 3, the value is displayed as 3.
When the PUE value is 1, it is invalid.
PUE Calculation Method
PUE = Increment in total system input electrical energy/Increment in
total electrical energy of system IT load output
PUE = Increment in total active electrical energy of device
input/Increment in total energy consumption of IT load output
When the configuration mode is set to Standard, the ECC800 can automatically calculate the PUE of
multiple devices connected in the N+1 and 2N scenarios.
Choose Query > Performance Data.
Set Device to ECC800, Performance data to Total system input electrical energy,
and Statistics mode to Hour, set other query criteria such as Start time and End time
as required, and click Query. Record the increment in total system input electrical
energy of the ECC800. Increment in total system input electrical energy = 110.0 kWh –
100.0 kWh = 10.0 kWh
