Monitoring and managing power
You can use iDRAC to monitor and manage the power requirements of the managed system. This helps to protect the system from power
outages by appropriately distributing and regulating the power consumption on the system.
The key features are:
• Power Monitoring — View the power status, history of power measurements, the current averages, peaks, and so on for the managed
system.
• Power Capping — View and set the power cap for the managed system, including displaying the minimum and maximum potential
power consumption. This is a licensed feature.
• Power Control — Enables you to remotely perform power control operations (such as, power on, power o, system reset, power cycle,
and graceful shutdown) on the managed system.
• Power Supply Options — Congure the power supply options such as redundancy policy, hot spare, and power factor correction.
Topics:
• Monitoring power
• Setting warning threshold for power consumption
• Executing power control operations
• Power capping
• Conguring power supply options
• Enabling or disabling power button

Monitoring power
iDRAC monitors the power consumption in the system continuously and displays the following power values:
• Power consumption warning and critical thresholds.
• Cumulative power, peak power, and peak amperage values.
• Power consumption over the last hour, last day or last week.
• Average, minimum, and maximum power consumption.
• Historical peak values and peak timestamps.
• Peak headroom and instantaneous headroom values (for rack and tower servers).
NOTE
: The histogram for the system power consumption trend (hourly, daily, weekly) is maintained only while iDRAC is running.
If iDRAC is restarted, the existing power consumption data is lost and the histogram is restarted.
