Switch On the Facility Circuit Breakers

---

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.

1. Confirm that you have properly installed and secured the server.

   See Installing the Server.

2. Confirm that you have properly attached the data cables to the server.

   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.

   ---

3. Power on all storage devices, expansion boxes, or peripherals connected to the server.

   Refer to the peripheral device documentation for instructions.

4. Switch on the power grid circuit breaker that supplies power to the cord connected to the AC input filter labeled AC0.

   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.

   ---

5. At the front of the server, confirm that the power supplies labeled PS5 and PS11 are powered on and that their green OK LEDs are lit.

   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.

6. Continue to switch on each power grid circuit breaker in the order of the AC input filters, and verify the operation of each power supply after switching on each circuit breaker.

   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.

   
   

   AC Input Filter Power Supplies AC0 PS5, PS11 AC1 PS4, PS10 AC2 PS3, PS9 AC3 PS2, PS8 AC4 PS1, PS7 AC5 PS0, PS6

   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.

7. Monitor the status indicators on the front or rear LED panel.

   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.

8. Continue with the installation by logging in to the Active SP.

   See Log In to the Active SP.
