Operations

Power up the server

The DX chassis firmware initiates an automatic power-up sequence when the servers are installed. If the default setting is
changed, use one of the following methods to power up each server:
• Use a virtual power button selection through iLO 5.
• Press and release the Power On/Standby button.
When the server goes from standby mode to full power mode, the server power LED changes from amber to green.

Power down the server

Before powering down the server for any upgrade or maintenance procedures, perform a backup of critical server data
and programs.
IMPORTANT: When the server is in standby mode, auxiliary power is still being provided to the system.
To power down the server, use one of the following methods:
• Press and release the Power On/Standby button.
This method initiates a controlled shutdown of applications and the OS before the server enters standby mode.
• Press and hold the Power On/Standby button for more than 4 seconds to force the server to enter standby mode.
This method forces the server to enter standby mode without properly exiting applications and the OS. If an
application stops responding, you can use this method to force a shutdown.
• Use a virtual power button selection through iLO 5.
This method initiates a controlled remote shutdown of applications and the OS before the server enters standby
mode.
Before proceeding, verify that the server is in standby mode by observing that the system power LED is amber.

Power capping

The HPE ProLiant DX family of products provides a power capping feature that operates at the server enclosure (chassis)
level. The capping feature can be activated using the HPE Apollo Platform Manager. After a power cap is set for the
enclosure all the resident servers in the enclosure will have the same uniform power cap applied to them until the cap is
either modified or canceled.
Using APM, the enclosure-level power capping feature can be expanded, or different caps can be applied to user-defined
groups by using flexible zones within the same rack. A global power cap can also be applied to all enclosures with one
APM command. For more information on using the APM, see the HPE Apollo Platform Manager User Guide (https://
www.hpe.com/support/APM_UG_en).

Power capping modes

The following Power Management modes are standard and are configurable in the power management controller:
NOTE: Mode 4 is only supported through APM.
