You can power a Server Module (blade) on or off using the ILOM web GUI or command-line interface (CLI), or by pressing the Power button.
The blade power-on policy is set by default to automatically return to its previous power state when the blade is inserted into a powered-on chassis. This means that the blade might not automatically power on to full 48V power mode when inserted into a powered-on chassis, depending on whether the blade had been powered on or off in its last use.
To apply full power to the blade, you need to use the ILOM web GUI or command-line interface (CLI), or manually press the Power button on the blade.
For more information about the setting the blade power-on policy, see Blade Power-On Policy.
The Chassis Monitoring Module (CMM) grants permission to power on the blade based on the last power-on state. If the last power-on state was ON and the CMM is down when you insert the blade, the blade will be unable to power on.
The blade power-on policy is in effect for the ILOM 1.1.5 firmware and later firmware updates. If you are using an ILOM firmware version before version 1.1.5, the Policy tab in the ILOM web GUI and the ILOM CLI power-on policy command are not available.
To initiate an orderly shutdown of the operating system and then to power off the blade, use one of these methods:
ILOM web GUI – See Control Blade Power From ILOM.
ILOM CLI – See stop /SYS.
Power button – Press the Power button on the blade (use a quick press).
Verify that the blade is powered off.
If you have successfully powered off the blade, the green OK LED will shut off.
After you insert a blade into a powered-on system, the blade's internal service processor (SP) is automatically brought online with 12V standby power (default blade power-on policy).
To apply full 48V power to a blade, use one of these methods:
ILOM web GUI – See Control Blade Power From ILOM.
ILOM CLI – See start /SYS.
Power button – Press the Power button on the blade (use a quick press).
Verify that the blade is powered on and operational.
The green OK LED will Slow Blink (1 on/off cycle per second) during the SP boot process, and will continue to Slow Blink during BIOS boot. When the blade is fully operational, the green OK LED remains SteadyOn.
You can change the default blade power-on policy by enabling the policy to power on the blade automatically to full power mode when it is inserted into a powered-on chassis. If you enable this policy, or if the blade was powered on manually using the Power button, when the blade boots next, it will receive main, 48V power.
To change the default power-on policy, use one of these methods:
ILOM web GUI – See Change Blade Policy From ILOM Web Interface.
ILOM CLI – See show /SP/policy and set /SP/policy.
