Applying Power To The Hp Integrity Rx8620 Server; Table 4-2. Bps To Cell Board Configuration To Achieve N+1 - HP Integrity rx8620 User's & Service Manual

Cabling and Power Up
Connecting AC Input Power
IMPORTANT The minimum supported N+1 BPS configuration for one cell board must have BPS slots 0, 1,
and 3 populated. When selecting a single power source, the power cords are connected into A0
and A1.

NOTE Label the AC power cords during the installation. One suggestion is to use tie wraps that have
the flag molded into the tie wrap. The flag can be labeled using the appropriate two characters
to represent the particular AC power input (for example, A0). Another suggestion would be to
use color coded plastic bands. Use one color to represent the first pair A0/A1 and another color
to represent the second pair B0/B1 (provided a second power source is available at the customer
site).

Applying Power to the HP Integrity rx8620 Server

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 Off. The front air intake
fans will flash a dim red color, the bulk power supplies will flash amber and an amber light is present on the
hard disk drives.
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 flash green and the
amber light is still present on the hard disk drives. The front panel On/Off switch is Off at this interval.
Housekeeping power is up at this point.
INTERVAL THREE
With the On/Off switch on the front of the server 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 turns green briefly and
then the LED turns off.
