Applying Power to the hp rp8400 Server Series

Initial observations can be made as to the functionality of the server before attaching any LAN or serial

cables, the system console or any peripherals to the server. When an active AC power source is first applied to

the server, the following observations can be made at three different intervals or points in time.

INTERVAL ONE

The power has just been applied to the server but the front panel On/Off switch is not On. The front air

intake fans will be flashing a dim red color, the bulk power supplies will be flashing amber and there will be

an amber light present on the hard disk drive(s).

INTERVAL TWO

After the power has been plugged into the server for about 30 seconds, the standby power turns on and the

front intake fan LED indicators turn solid green. The Bulk Power Supplies (BPS) will be flashing green and

the amber light is still present on the hard disk drive(s). The front panel On/Off switch is not On at this

point. House keeping power is up at this point.

INTERVAL THREE

With the On/Off switch on the front of the server is set to On, the intake fans spin up and become noticeably

audible while the LED indicator remains solid green. The BPS LED indicator turns a solid green and the PCI

backplane power supply LED indicators turn solid green. The hard disk drive LED will turn green briefly and

then the LED will turn off.
