Failure of one of the power supplies.
Service actions that require removal of one of the power supplies.
Refer to the SPARC T4-2 Server Service Manual for power supply replacement instructions.
Note - Input power cables: To avoid missing initialization messages, do not attach power cables to the power supplies until you have finished connecting the data cables and have connected the server to a serial terminal or a terminal emulator (PC or workstation). The server goes into Standby mode and the Oracle ILOM SP initializes as soon as the input power cables are connected to the power source.
