Power Off From Main Power
●
To power off the server module from main power mode, use one of the
following two methods:
■
Graceful shutdown –
Press and release the Power button on the front panel.
This operation will cause any Advanced Configuration and Power Interface
(ACPI) enabled operating system to perform an orderly shutdown of the
operating system. Servers not running ACPI-enabled operating systems will
shut down to standby power mode immediately.
■
Emergency shutdown –
Press and hold the Power button for five seconds to
force main power off and to enter standby power mode.

Troubleshoot Server Power States
Each time a server module powers on in the Sun Blade 6000 Series chassis, it queries
the CMM to ensure that there is enough power available from the power supply
units (PSUs) to power on the server module. If there is not enough power to power
on the server module, the SP denies the server module from receiving power
(standby and main). If this situation occurs, the OK/Power LED on the front panel
of the server module will remain off. To troubleshoot this power issue, follow these
guidelines:
1. Review the ILOM event log messages to determine whether the server module
has permission to power on. An event message is recorded in the log any time
there is inadequate amount of power available from the PSUs to power on the
server module.
For more information about the ILOM event log or monitoring power
consumption, refer to the
Oracle Integrated Lights Out Manager (ILOM) 3.0
Documentation Collection
(see
“Related Documentation” on page viii
for part
numbers).
2. Ensure that the system chassis has the proper amount of power supplies installed
to support powering on all the chassis components that are currently installed.
Refer to the system chassis documentation for information about the number of
power supplies required to power on chassis components.
3. To avoid power loss, it is recommended that you use the
default
CMM power
management settings in ILOM for power supplies.
For more information about power management, refer to the information about
power management policy in the
Oracle Integrated Lights Out Management (ILOM)
3.0 Concepts Guide
(820-6410).
