I/O Side V12

Two hot-swappable ac/dc power supplies generate main system power, and a standby power voltage. One active power supply is sufficient to operate the system at maximum load. Each power supply receives ac power through the integrated ac inlet. The system can operate at 100-240 VAC and achieve 1+1 redundancy. The power supplies are power factor corrected and the maximum dc power output of the power system is 1095 watts. Service the hot-swappable power supplies are serviced by sliding them out the rear of the chassis.

Applying system power in normal customer usage, the rx3600 runs on 100 to 240 V. Standby power will be supplied on either; hence the BMC will power up when the power supplies are plugged in. The BPS0_AC_OK and BPS1_AC_OK signals indicate whether the ac voltage to the power supplies is within the required range. If neither BPS0_AC_OK nor BPS1_AC_OK is asserted, then the BMC should log an event and prevent the system from turning on.

Power Button The power button on the rx3600 is a momentary contact push button. The BMC polls the front panel power button at a rate of at least 2 Hz. The power button is an input to the System Power State Management. If the system is off, a single button press will turn on the system. If the system has booted to an OS, and a short button press is detected, a graceful-shutdown request will be sent to the system by pulsing ACPI_PWR_BTN_L; when the ACPI bits are set to note the O/S has shut down, the BMC will perform a hard power down. If the system has not booted to an OS, or if a long (5 second) button press is detected, the system will do an immediate hard power off.

System Power State Management The system power may be controlled from the power button, an IPMI Chassis command, Wake-On-LAN, loss or gain of ac.

Power On Sequence:

1.Update the cache of DIMM SPD information.

2.Ensure that the memory board is detected and that the cpu board has a processor in socket 0. If these FRUs are not detected the BMC logs an event against the Missing Device sensor (sensor 0x15).

3.Check for a BPS0_AC_OK or a BPS1_AC_OK signal. If neither is asserted, then the ac supply has a problem.

4.If any FRUs are missing or both ac supplies are not valid, then return to power off state.
