Power

Basic information

Slot number, vendor, type, serial number, firmware version, rated power, input mode, input voltage, output voltage, and BOM code of the PSU.

Current Power

Output power of the PSU.

Work Mode

PSU working mode.

Value:

• Load balancing: Multiple PSUs simultaneously supply power to the server and share the server power consumption.
• Active/Standby: One or more active PSUs supply power to the server, and the other PSUs are in standby state.

  This mode provides a higher power supply efficiency and extends the PSU service life.

Default value: Load balancing

Active PSU

Active PSUs.

Hibernate

Setting of the deep hibernation function.

If deep hibernation is enabled, certain PSUs enter the deep hibernation mode and stop outputting power when the server is powered off. When the server is powered on, the PSUs in deep hibernation mode continue to output power.

Click or , and click Save.

• : enables deep hibernation. The setting takes effect when the OS is powered off.
• : disables deep hibernation. The setting takes effect when the OS is powered off.

Power Status

Select the power unit, which can be W or BTU/h.

Statistics Collected

Start time for power statistics collection.

Reset Statistics

Clears the current statistics and starts to collect statistics again.

Set Power Cap

The lower limit for Power Cap is the minimum value allowed. However, if Power Cap is set to a value close to the lower limit for the server equipped with high-power PCIe devices such as GPUs and SSDs, power capping may fail.

Power capping

Power capping function, which can be enabled or disabled.

Power Cap (W)

Maximum power allowed for the server in running.

Value range: After power capping is enabled, the value range will be displayed after you click the Power Cap text box.

The value range varies according to the server model.

The power cap value cannot be smaller than the lower limit of the recommended value range.

Current Power

Current power of the server.

Peak Power

Maximum power collected since the first time the server was powered on or since the last statistics collection start time.

Average Power

Average power collected since the first time the server was powered on or since the last statistics collection start time.

Total Consumed Power

Total power collected since the first time the server was powered on or since the last statistics collection start time.

Power History

Displays the server peak and average power statistics in any time period (accurate to 10 minutes) in the last week.

Alarm Threshold

Alarm threshold of the real-time power. Set the alarm threshold according to the value range displayed on the WebUI.

When the power exceeds the threshold, the iBMC generates an alarm.

Download

Click Download to download the historical power data to the local PC.

Clear

Click Clear to clear all historical power data.

After the historical power data is cleared, the iBMC recollects statistics from the current time. The Power History area displays the power statistics recollected.

System Power

Current status of the server OS.

Power On

Starts the server OS.

Power Off

Shuts down the server OS.

Power-off Timeout (s)

The iBMC acts according to the setting of Power-off Timeout after the Power Off button is clicked to shut down the server OS.

• If Power-off Timeout is enabled, the iBMC forcibly shuts down the OS when the OS fails to shut down within the specified timeout period.
• If Power-off Timeout is disabled, the iBMC does not interfere with the OS shutdown process.

The value range and default value of Timeout Period vary depending on the server model. For details, see the information displayed on the WebUI.

For the server that supports BBU module, the value range of Power-off Timeout is 180 to 6000 if BBU module is installed. In other cases, the value range is 10 to 6000.

Select the check box of Power-off Timeout to enable the power-off timeout.

Click and enter a value in the text box, and click to save the settings.

Forced Power Off

Forcibly powers off the server OS within 6 seconds after this button is clicked.

Forced System Reset

Resets the server OS.

Forced Power Cycle

Forcibly shuts down the server OS, and about 6 seconds later, starts the OS again.

Disable Panel Power Button

Disables the power button on the server panel.

Click or and save the settings.

Default value:

If you set this parameter to , the power button on the server panel does not work.

System State Upon Power Supply

After the server PSUs are powered on, the OS startup policies can be any of the following:

• Power On: Automatically starts the OS after the power supply is restored.
• Remain Off: Keeps the server OS shut down even after the power supply is restored.
• Restore Previous State: Restores the OS to the state before the power failure.
  • If the server OS is started before the power failure, the server OS starts automatically after the power supply is restored.
  • If the server OS is shut down before the power failure, the server OS is shut down after the power supply is restored.

The default value is Power On.

Power-On Delay

The power-off of the upper-level power supply equipment will cause simultaneous power-on of a large number of server. The spike peak current will adversely cause great impact on the power supply equipment and may damage the power supply equipment. To prevent this problem, you can set the power-on delay to postpone the servers from powering on for a specified time.

Auto Power-Off upon Leakage

If this function is enabled, the OS will automatically power off when the iBMC detects a water leakage alarm.

This function is available only for the servers that support leakage detection cards.

• To enable this function, set this parameter to .
• To disable this function, set this parameter to .

It is set to by default.
