Power Consumption Information
NOTE When the PC Workstation is turned off with the power button on the
front panel, the power consumption falls below 5 Watts, but is not zero.
The special on/off method used by this PC Workstation considerably
extends the lifetime of the power supply. To reach zero power
consumption in “off” mode, either unplug the PC Workstation from the
power outlet or use a power block with a switch. You should be aware
that, in this case, the PC Workstation will lose its time settings within a
few days.
Maximum Loads Available for Accessory Slots
The load limits for the ISA and PCI accessory slots are compliant with
ISA and PCI specifications. More details of permitted loads are
provided on the World Wide Web in the support documentation section
for your PC Workstation.
Maximum power consumption 260 W
Typical consumption with:
•One processor installed
•Two processors installed
approx. 85 W
approx. 99 W
Off 2.5 W1
1. The power supply in your PC Workstation continues to supply power to the CMOS
memory, even when switched off.

The HP FastRAID Option
10 English
Network Features
The HP FastRAID Option
HP FastRAID uses RAID technology to accelerate the performance of
your PC’s hard drives. Rather than focussing on data protection, as
with server-based RAID technologies, HP FastRAID brings top
performance to your computer.
If you purchased your computer with the HP FastRAID option, an
Adaptec ARO-1130 PCI RAIDport™adapter will have been pre-
installed in the RAIDport connector slot of your PC’s system board, and
configured to provide maximum I/O throughput for your PC’s two hard
drives.
Although your ARO-1130 adapter and hard drives come pre-configured
for maximum performance (RAID 0), you can also configure the
RAIDport adapter and drives to provide protection against data loss
(RAID 1).

Audio Front Panel
Connector
The Audio Front Panel Connector, labeled “Audio Front Panel,” is a
10-pin connector that links the system board with the multimedia Front
Panel. This connector directs stereo output to either the front panel
headphone jack or the rear panel stereo jack, as follows:
•When the headphone jack on the Audio Front Panel of the
PC Workstation is not being used, the audio signal is available on the
rear panel and the internal speakers are active.
•When external speakers are plugged into the rear jack, the audio
signal is directed to the rear jack and the internal speakers are
muted.
•When a headphone is plugged into the headphone jack, the audio
signal is directed to the headphone jack, no sound is available on the
rear panel and the internal speakers are muted.
The Audio Front Panel Connector has the following pin assignments:
