|Netra Blade X3-2B (formerly Sun Netra X6270 M3 Server Module) HTML Document Collection|
Each time a blade powers on in a Sun Netra 6000 modular system, it queries the CMM to ensure that there is enough power available from the power supply units (PSUs) to power on the blade.
If there is not enough power to power on the blade, the CMM prevents the blade from receiving main power. If this situation occurs, the OK/Power LED on the front panel of the blade remains at standby blink.
To troubleshoot this power issue, follow these guidelines:
Review the Oracle ILOM event log messages to determine whether the blade has permission to power on. An event message is recorded in the log any time there is inadequate amount of power available from the chassis PSUs to power on a blade.
For more information about the Oracle ILOM event log or monitoring power consumption, see the Oracle Integrated Lights Out Manager (ILOM) 3.1 documentation library.
Ensure that the system chassis has the proper number of power supplies installed to support powering on all the chassis components that are currently installed.
See the system chassis documentation for information about the number of power supplies required to power on chassis components.
To avoid power loss, use the default CMM power management settings in Oracle ILOM for power supplies.
For more information about power management, see the Oracle ILOM 3.1 documentation.
Note - When power-on permissions become available, the OK/Power LED on the front panel of the blade illuminates a standby blink.
As needed, see the Oracle x86 Server Diagnostics Guide for instructions on how to run the start up diagnostic tools provided with the blade.
