Caution - This procedure provides the safest and preferred way of supplying facility power to the server by switching on the facility circuit breakers in sequential order. If you do not have access to the circuit breakers and the facility power grids are on, connect the power cord IEC 60309 plugs to the live facility power grid sockets in the order of the AC input filters.
Ensure that you have connected the following cables:
Serial cables and network cables to the two SPs – Connecting the Front SP Cables
At least one network cable to each PDomain – Connect the EMS Network Cables
Any cable required for peripherals – Connect Other Data Cables
Note - If you power on the server without first connecting terminal devices to the SER MGT ports, you will not see the system power-on messages.
Refer to the peripheral device documentation for instructions.
Consult with your facilities manager or a qualified electrician for the specific instructions on how to use the circuit breakers at your data center.
Note - If you do not have access to the circuit breakers and the facility power grids are on, connect the power cord IEC 60309 plug labeled AC0 to the live facility power grid socket.
Do not proceed to the next step until you have confirmed that these two power supplies are operating normally.
Note - The green OK LEDs of the remaining power supplies will remain off until they receive AC power in Step 6.
Note - The server can operate with eleven power supplies if one has failed. (The server must contain eleven power supplies to cool the IOU components.) The server requires twelve power supplies for proper cooling and for power supply redundancy, so replace any failed power supply as soon as possible. Refer to the Server Service, servicing power supplies, for instructions.
Confirm that the green OK LEDs on the appropriate power supplies are lit after switching on each circuit breaker. Use the following table to determine which AC input filter powers which power supplies. See Power Cord-to-Power Supply Relationship for more information.
Note - If you do not have access to the circuit breakers and the facility power grids are on, connect the power cord IEC 60309 plugs to the live facility power grid sockets in the order of the AC input filters.
Soon after you connect AC power to the server, one of the two SPs will assume the role of the Active SP. The front and rear panel SP LEDs blink as the Active SP powers on, runs diagnostics, and initializes the Oracle ILOM firmware. See System Status LEDs for a description of these status indicators.
After the Oracle ILOM firmware initializes, the front and rear panel SP LEDs remain lit (the preceding illustration shows the front panel SP LED) and the login prompt displays on the Active-SP terminal device. The host is not yet initialized or powered on.
