1-8 Compaq ProLiant 8500 Servers Setup and Installation Guide System Power Management Guidelines Unless operating with two 1150W power supplies at 220V, it may be necessary to make tradeoffs with respect to which options can be added and powered with the installed power supplies. Use the following guidelines when evaluating these tradeoffs. NOTE: The following guidelines are general. Use the Windows NT Power Supply Viewer Utility and option documentation to obtain the most accurate power capacity and assessment of power margin. s Comparing processor and hard drive power: two processors draw as much current as five to six hard drives. s Comparing memory and 3.3V-powered PCI Expansion Board power: each additional 512MB draws approximately as much current as one to two PCI boards. s Comparing hard drive and 5V-powered PCI Expansion Board Power: one PCI card draws as much current as two to five hard drives. s In general, PCI array controllers draw more current than PCI NICs. s For example, if the available capacity of the installed power supplies permits adding two processors, you have the option of adding:  two processors,  one processor and three hard drives, or  up to four hard drives Remote-Flash Redundant ROM This server is equipped with a Remote-Flash Redundant ROM that gives the system the ability to recover the last known good system ROM in the event that the current system ROM has been corrupted. When the server leaves the factory both system ROMs will contain the same image. Through subsequent boots of the server, if any integrity errors are detected by the boot block then the system will automatically launch the redundant image and continue the POST process. If this occurs, you will see a "105" error message saying which system ROM had been deemed faulty. The ROMPaq utility will flash the failed system ROM to the latest released version.

Compaq ProLiant 8500 Servers Setup and Installation Guide
System Power Management Guidelines
Unless operating with two 1150W power supplies at 220V, it may be
necessary to make tradeoffs with respect to which options can be added and
powered with the installed power supplies. Use the following guidelines when
evaluating these tradeoffs.
NOTE:
The following guidelines are general. Use the Windows NT Power Supply Viewer
Utility and option documentation to obtain the most accurate power capacity and
assessment of power margin.
■
Comparing processor and hard drive power: two processors draw as
much current as five to six hard drives.
■
Comparing memory and 3.3V-powered PCI Expansion Board power:
each additional 512MB draws approximately as much current as one to
two PCI boards.
■
Comparing hard drive and 5V-powered PCI Expansion Board Power:
one PCI card draws as much current as two to five hard drives.
■
In general, PCI array controllers draw more current than PCI NICs.
■
For example, if the available capacity of the installed power supplies
permits adding two processors, you have the option of adding:
±
two processors,
±
one processor and three hard drives, or
±
up to four hard drives
Remote-Flash Redundant ROM
This server is equipped with a Remote-Flash Redundant ROM that gives the
system the ability to recover the last known good system ROM in the event
that the current system ROM has been corrupted. When the server leaves the
factory both system ROMs will contain the same image. Through subsequent
boots of the server, if any integrity errors are detected by the boot block then
the system will automatically launch the redundant image and continue the
POST process.
If this occurs, you will see a “105” error message saying which system ROM
had been deemed faulty. The ROMPaq utility will flash the failed system
ROM to the latest released version.
