NOTE: It is common to see some instantaneous values exceed the Power Cap value in the
Maximum line. Power Center monitors this value and controls it to the normal power range with
this happens. You only need to pay attention when the Average power value exceeds the Power
Cap value.
NOTE: You can set the time interval (the period from a time point to the next time point) in the
Settings page. For information on configuring the interval, see Monitoring Settings.
Power details for racks
For racks, you can click Devices → Managed Group → Details to display PDU power consumption for all
rack PDUs.
You can also click Devices → Managed Group → Policies to change a power policy.
You can view the following power details of PDU devices. For more information on supported PDU
devices, see System Requirements.
• PDU device information, including PDU name, model, and IP address.
• PDU outlet information, including outlet number, power (W), voltage (V), amps (A), and the time of the
information recorded, following the format <YYYY-MM-DD HH:MM:SS>. The table lists the
information for each outlet and the total power consumption for all outlets.
查看能耗
每个设备和设备组功耗的详细信息可在设备屏幕上的所有选项卡中获得。
• IT 设备能耗 — 所选设备或设备组中所有托管设备的总能耗和费用。
注: 设备处于 S0（开）状态时，Power Center 可读取设备的功耗。对于处于 S4/S5 状态的设备，
Power Center
使用固定值 (30W) 来计算功耗。
• 冷却能耗 — 冷却所选设备/组所需的估计能耗和费用。
冷却能耗 = IT 设备能耗 * 冷却系数
您可在设置 → 监测屏幕上的能耗费用部分配置冷却系数。
• 能耗（全部） — IT 设备能耗和冷却能耗的总能耗和费用。公式为：
成本 = （ IT 设备能耗 T1* 冷却系数） * 单位电价 T1+ （ IT 设备能耗 T2* 冷却系数） * 单位电价 T2+°¦+ （ IT 设
备能耗
Tn* 冷却系数） * 单位电价 Tn
注: T1/T2/.../Tn 表示某一特定单位电价的时间范围（以小时计算）。
注: 默认情况下，费用列显示为 0。您必须配置单位电价才能查看费用。单位电价为全局设置，可在
设置 → 监测页面进行设置。
注: 能耗费用部分根据设置屏幕中配置的值显示信息。该信息应仅用作估计值。
