Executing Power Control Operations

iDRAC7 enables you to remotely perform a power-on, power off, reset, graceful shutdown, Non-Masking Interrupt (NMI),
or power cycle using the Web interface or RACADM.
You can also perform these operations using Lifecycle Controller Remote Services or WS-Management. For more
Lifecycle Controller Remote Services Quick Start Guide available at dell.com/support/manuals and

Dell Power State Management profile document available at delltechcenter.com.

Executing Power Control Operations Using Web Interface

To perform power control operations:
1. In iDRAC7 Web interface, go to Overview → Server → Power/Thermal → Power Configuration → Power Control.
The Power Control page is displayed.
2. Select the required power operation:
– Power On System
– Power Off System
– NMI (Non-Masking Interrupt)
– Graceful Shutdown
– Reset System (warm boot)
– Power Cycle System (cold boot)
3. Click Apply. For more information, see the

Executing Power Control Operations Using RACADM

To perform power actions, use the serveraction command. For more information, see the
Reference Guide for iDRAC7 and CMC available at dell.com/support/manuals.

Power Capping

You can view the power threshold limits that covers the range of AC and DC power consumption that a system under
heavy workload presents to the datacenter. This is a licensed feature.

Power Capping in Blade Servers

Before a blade server powers up, iDRAC7 provides CMC with its power requirements. It is higher than the actual power
that the blade can consume and is calculated based on limited hardware inventory information. It may request a smaller
power range after the server is powered up based on the actual power consumed by the server. If the power
consumption increases over time and if the server is consuming power near its maximum allocation, iDRAC7 may
request an increase of the maximum potential power consumption thus increasing the power envelope. iDRAC7 only
increases its maximum potential power consumption request to CMC. It does not request for a lesser minimum potential
power if the consumption decreases. iDRAC7 continues to request for more power if the power consumption exceeds
the power allocated by CMC.
After, the system is powered on and initialized, iDRAC7 calculates a new power requirement based on the actual blade
configuration. The blade stays powered on even if the CMC fails to allocate new power request.
CMC reclaims any unused power from lower priority servers and subsequently allocates the reclaimed power to a
higher priority infrastructure module or a server.
