All dc7900 Series models featuring this technology include processors which
are part of the Intel 2008 Stable Image Platform Program (SIPP) designed to
ensure the stability promise inherent in the value proposition of the HP
Compaq dc7900 Series business desktop, thus making these model the most
stable, secure, and manageable platforms available to enterprises today.
The 2008 SIPP processors are:
Core 2 Duo E8400, E8500, E8600
Core 2 Quad Q9400, Q9550, Q9650
Intel's Core 2 Processor with vPro Technology suite of features includes:
Intel Active Management Technology
an advanced set of remote management features and functionality
which provides network administrators the latest and most effective
tools to remotely discover, heal, and protect networked client systems
regardless of the system's health or power state. Intel Active
Management Technology includes all features described as part of
Intel Standard Manageability plus the following advanced management
functions:
Fast Call for Help
– a client inside or outside the firewall may
initiate a call for help via BIOS screen, periodic connections, or
alert triggered connection
Remote Scheduled Maintenance
– pre-schedule when the PC
connects to the IT or service provider console for maintenance.
Remote PCs can get required patches, be inventoried, etc by
connecting to their IT console or Service Provider when it's
convenient
Remote Alerts
– automatically alert IT or service provider if
issues arise
Access Monitor
– Provides oversight into Intel® AMT actions to
support security requirements
Microsoft NAP Support
Allows Intel Active Management Technology to gain access to a
Microsoft NAP enabled 802.1x network OOB to enable OOB SW
updates, inventories, remote diagnostics, etc. NAP is a new platform
and solution that controls access to network resources based on a
client computer's identity and compliance with corporate governance
policy. NAP allows network administrators to define granular levels of
network access based on who a client is, the groups to which the client
X X X
QuickSpecs
HP Compaq dc7900 Business PC
Standard Features and Configurable Components
DA - 13029 Worldwide QuickSpecs — Version 24 — 10/30/2009
Page 10
belongs, and the degree to which that client is compliant with corporate
governance policy. If a client is not compliant, NAP provides a
mechanism to automatically bring the client back into compliance and
then dynamically increase its level of network access.
When a client attempts to access the network or communicate on the
network, it must present its system health state or proof of health
compliance. If a client cannot prove it is compliant with system health
requirements (for example, that it has the latest operating system and
antivirus updates installed), its access to the network or communication
on the network can be limited to a restricted network containing server
resources so that health compliance issues can be remedied. After the
updates are installed, the client requests access to the network or
attempts the communication again. If compliant, the client is granted
unlimited access to the network or the communication is allowed.
Memory
DDR2 SYNCH DRAM NON-ECC MEMORY
Memory upgrades are accomplished by adding single or multiple DIMMs of the same or varied
sizes. This chart does not represent all possible memory configurations. The HP Compaq dc7900
business desktop supports non-ECC DDR2 PC2-5300 (667-MHz) and PC2-6400 (800-MHz)
memory.
CAUTION:
You must shut down the computer and disconnect the power cord before adding or
removing memory modules. Regardless of the power-on state, voltage is always supplied to the
memory modules as long as the computer is plugged in to an active AC outlet. Adding or removing
memory modules while voltage is present may cause irreparable damage to the memory modules
or system board.
HP recommends dual-channel symmetric configurations for maximum performance.
For best performance, add the same amount of total memory to each channel and do not mix
speeds. For dual-channel symmetric performance, the total amount of memory in each channel
must be equal. If speeds are mixed, speed will default to the slowest DIMM.
RAID
Redundant Array of Independent Drives
Fl
exible implementation:
DriveLock is supported while in RAID mode. Users can manage DriveLock password from
within F10 Setup. Locked drives will be displayed as such in the RAID option ROM interface.
Hard drive information can be viewed within F10 Setup while in RAID mode. Previously, the
hard drives will not appear in Drive Configuration when switching to RAID mode.
DPS Self Test can be executed on physical hard drives while in RAID mode.
The RAID Setup Utility (accessed through CTRL-I) can be protected by the F10 Setup
password.
NOTE:
RAID 1 is the only RAID configuration that HP Compaq dc7900 Business PC products
offer as factory configurations. The pre-configured systems:
Are only available on the CMT and SFF form factors. The USDT does not support RAID as it
does not allow for more than one hard disk drive.
Are complete RAID systems and have both drives installed.
Have the necessary Option ROM configuration.
Are pre-loaded and pre-installed with all required Intel software.
Include a preinstalled operating system that is mirrored mode out of the box.
Please refer to the HP White Paper titled "Advanced Host Controller Interface (AHCI) and
Redundant Array of Independent Disks (RAID) on HP Compaq dc7900 Business PCs" at

ADI control panel to allow independent audio streams to be sent to/from the
front and rear jacks. This allows for different audio applications to use
separate audio ports on the system. For example, the front jacks could be
used with a headset for a communications application while the rear jacks
are being used with external speakers and a multimedia application.
