HP Compaq dc7900 User Manual

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.
