HP INTEGRITY RX3600 - Manual (Page 79)

AC Input Power
The server can receive ac input from two different ac power sources. If two separate power
sources are available, you can plug the server into the separate power sources, increasing system
reliability if one power source fails. The power receptacles are located at the rear of the chassis.
They are labeled PWR 0 and PWR 1.
You can install a maximum of two bulk power supplies (BPS) in the server. Installing two BPSs
in the server provides 1+1 redundancy, meaning that if one BPS fails, there is still enough power
supplied to the server for it to remain operational. You must promptly replace the failed BPS to
restore 1+1 functionality.
A minimum of one BPS is required to power the server. There is no 1+1 capability if only one
BPS is present.
Power States
The server has three power states:
•
standby power
• full power
• off
To get to standby power state plug the power cord into the appropriate receptacle on the rear
of the chassis. The front panel power button is not turned on.
Full power occurs when the power cord is plugged into the appropriate receptacle and either
the power is activated through the iLO 2 MP PC command, or the power button is activated.
In the off state, the power cords are not plugged in.
Table 3-8 lists the server power states.
