The CMM Power-On Policy controls how much power is applied to the system chassis and its modules after the CMM initially boots up. A brief description of the CMM Power-On Policy options and default settings follows:
Auto-Chassis-Power-On (shipped enabled). When the "Auto-Chassis-Power-ON" option is enabled, this option automatically powers on the system chassis, fans, and EMs with main power. It also applies power to the blades and their associated NEMs based on the blade's SP current power-on policy that is in effect (for example, always off, main power, or last power-on state).
Blade and EM connections are powered on and off as a pair. When power is disabled on a blade, it is also disabled on its associated EM (if an EM is configured). EMs are not supported on the Sun Blade 8000 P Chassis.
The Sun Blade 8000 Series Chassis must have at least three power supplies receiving power for the Auto-Chassis-Power-On policy to take effect. If fewer than three chassis power supplies are receiving power, you will need to manually apply main power to the chassis by pressing the system chassis Power button.
When the Auto-Chassis-Power-on Policy option is disabled, the CMMs will not power on the chassis but instead will wait for user action (via Chassis Power button or ILOM remote power controls) to apply main power.
If two CMMs are present in the chassis, the current power-on policy that is in effect on the active CMM applies.
For more information about the blade power-on policy options, see Blade SP Power-On Policy.
ILOM 1.x option -- Three or More Power Supplies to Power-On (shipped enabled). The "Three or More Power Supplies to Power ON" option is only available in ILOM 1.x. When this option is enabled, the system must have at least three or more power supplies installed and operating to apply main power to the system chassis and its modules. Also, when this option is enabled, the “three or more power supplies” requirement applies to power supply hot-plugging operations in a powered- on chassis. For example, if this option is enabled and only three power supplies are installed and operating in the chassis, hot-removal of a power supply module from a powered-on chassis is prevented. For more information about power supply hot-plug procedures, see Replace Power Supply (Sun Blade 8000 Chassis) and Replace Power Supply (Sun Blade 8000 P Chassis).
When the Three or More Power Supplies to Power-On option is disabled, power is applied to the system chassis and its modules (after the CMM boots) based on the number of power supplies installed and operating. If three or more power supplies are installed and operating, then main power is applied. If fewer than three power supplies are installed and operating, standby power is applied to the chassis.
Physical NEM Attention Push Buttons are Enabled (shipped enabled). When the "Physical NEM Attention Push Buttons" are enabled, this option allows the NEMs to be hot-plugged within a powered-on chassis. When disabled, this option forces users to initiate the hot-plug NEM operation from ILOM or via the NEM Attention push button. For information about the NEM hot-plug procedure, see Replace a Network Express Module.
