iRMC S2/S3 195
Power Management
Enabled
Enables 0 Watt mode.
Even if Enabled has been configured, the 0 Watt mode is blocked in the
following cases:
● Power-cycle request / power-on delay
A power cycle request powers down the server without enabling
0Watt mode, i.e. 0 Watt mode will not be enabled in the delay between
powering down and powering up during a power cycle:
– Any power-on request occurring within the delay causes the
server to be powered on after the delay is over.
– If no power-on request occurred during the delay, the iRMC S3
enables the 0 Watt mode after the delay time period has passed.
● Thermal power-on prohibition
If the Temperature Monitoring mode (system thermal power on
prohibition) has been configured in the BIOS/UEFI setup menu, 0 Watt
mode will not be enabled.
● ASR&R
Any ASR&R action currently reducing the retry counter prevents
0Watt mode from being enabled. This applies even if the server was
finally powered off after the retry counter reached 0.
● Scheduled Power On/Off Time (see "Power On/Off Time - Specify
power on/off times for the server" on page 193)
As long as a Power On/Off timer configured in the iRMC S3 Power
Options page is active, 0 Watt mode cannot be enabled.
0 Watt mode also cannot be enabled if the Power On/Off timer gets
deactivated while the server is powered off. In this case, only next
power-off transition will enable 0 Watt mode. No scheduled Power
On/Off timer will then prevent 0 Watt mode from being enabled.
● Global Error LED
If the global Error LED indicates any problematic system health
conditions, the iRMC S3 will not enable 0Watt mode. This is because
the server must be able to report system health problems even if
powered off.
