Powering the Host On and Off
Your server has three power modes (states): power off, Standby power, and Main power.

|
|
|
|
|
The server is completely powered off when the AC power cords are
disconnected.
|
All indicators are off.
The server is disconnected from all power sources.
|
Disconnect all four power cords to completely remove power.
Caution -
Equipment damage. Do not disconnect power cords when system is
in Main power mode. Place all systems in Standby power mode
before disconnecting power cords.
|
|
|
|
In Standby power mode, the host is powered off but the SP is
powered on.
|
The green system System OK indicator flashes slowly.
The green SP OK indicator is steady on.
|
If the server is completely powered off, plug in all four power
cords to apply Standby power.
If the server is in Main power mode, use Oracle ILOM or the Power
button to remove host power. On dual 4-socket systems, complete this
action for both servers.
You can power the host off gracefully, or immediately.
|
|
|
When you power on the host, the server enters Main power
mode.
|
In Main power mode, the green System OK indicator is steady
on.
On single 4-socket and single 8-socket systems,only the System OK
indicator for System A (SMOD0) comes on.
|
Use Oracle ILOM or the On/Standby button to apply host
power.
On dual 4-socket systems, you must complete this action for both
servers.
