Owner's Manual

• Energy Consumed (Total) — The combined energy consumption and costs for the IT equipment and cooling

energy. The formula is:

Cost = (IT Equipment Energy T1*Cooling Multiplier) *Flat Rate T1+(IT Equipment Energy T2*Cooling Multiplier)

*Flat Rate T2+°¦+(IT Equipment Energy Tn*Cooling Multiplier) *Flat Rate Tn

NOTE: T1/T2/.../Tn is the time period (in hours) at a certain flat rate.

NOTE: By default, the Cost column displays 0. You must configure the cost rate to see the cost. The rate is

a global setting, and can be set on the Settings → Energy Consumption page.

NOTE: The Energy Consumption section displays information based on the values configured in the

Settings page. This information should be used as an estimate only.

NOTE: When a device or group is newly-added or created in Power Center, the power and energy

consumption data displayed in the "1W" and "1M" time windows are different if the monitored time is less

than 1 week, and the data displayed in the "1H" and "1D" time windows are different if the monitored time is

less than 1 day. This occurs because Power Center uses different sampling intervals for different time

windows. For example, a device is added into Power Center at 2011-10-15 09:00, and the current time is

2011-10-17 11:10. For the 1M time window (sampling interval is 1 day), the power and energy consumption

is calculated from 2011-09-17 00:00 to 2011-10-17 00:00. For the 1W time window (sampling time is 1 hour),

the power and energy consumption is calculated from 2011-10-10 11:00 to 2011-10-17 11:00. There is an 11

hour gap; therefore, the data displayed in the two time windows are not the same.

Monitoring PDU Power

To monitor PDU power, click Groups in the left pane, navigate to the PDU, and click the Overview tab. The PDU

Dashboard displays all PDU information.

The boxes in the PDU Dashboard show the instantaneous power value of the PDU. The Dashboard page also lists the

PDU details read from the device. It displays NA when the data is not provided on the PDU device.

Monitoring UPS Power

To monitor UPS power, click Groups in the left pane, navigate to the UPS, and click the Overview tab. The UPS

Dashboard displays all UPS information.

The boxes in the UPS Dashboard show the instantaneous power value of the UPS. The Dashboard page also lists the

UPS details read from the device. It displays NA when the data is not provided on the UPS.

Power Dashboard

You can monitor the Power Center overall status from the Dashboard.

1. Click Groups in the left pane.

2. Click the group/device icon.

3. Click Overview.

4. The Dashboard displays.

For devices (Excludes PDU and UPS):

– The left box displays the average power consumption of the latest sampling interval.

– The right box displays the level of the average power consumption by comparing it with the power

thresholds you set in the Thresholds tab.
