Monitoring Power and Executing Power Control
Commands on the Chassis
You can use the Web interface or RACADM to:
• View the system’s current power status.
• Perform an orderly shutdown through the operating system when
rebooting, and power the system on or off.
For information about power management on CMC and configuring power
budget, redundancy, and power control, see "Power Management" on
page 289.
Viewing Power Budget Status
For instructions on viewing power budget status for the chassis, servers,
and PSUs using either the Web interface or RACADM, see "Viewing Power
Consumption Status" on page 311.
Executing a Power Control Operation
For instructions on powering on, powering off, resetting, or power-cycling the
system using the CMC Web interface or RACADM, see "Executing Power
Control Operations on the Chassis" on page 327, "Executing Power Control
Operations on an IOM" on page 329, and "Executing Power Control
Operations on a Server" on page 330.
Power Troubleshooting
Use the items below to assist in troubleshooting power supply and
power-related issues:
• Problem: Configured the Power Redundancy Policy to AC Redundancy ,
and a Power Supply Redundancy Lost event was raised.
–
Resolution A : This configuration requires at least one power supply in
side 1 (the left three slots) and one power supply in side 2 (the right
three slots) to be present and functional in the modular enclosure.
Additionally the capacity of each side must be enough to support the
total power allocations for the chassis to maintain
AC redundancy .
(For full AC Redundancy operation, ensure that a full PSU
configuration of six power supplies is available.)
