Fault Notification and Recovery

Fault Notification and Recovery features combine innovative hardware and software technology to prevent
the loss of critical data and minimize unplanned downtime.
If the workstation is connected to a network managed by HP Client Manager Software, the computer
sends a fault notice to the network management application. With HP Client Manager Software, you can
also remotely schedule diagnostics to automatically run on all managed PCs and create a summary report
of failed tests.

Drive Protection System

The DPS is a diagnostic tool built into the hard drives installed in select HP workstations. DPS is designed
to help diagnose problems that might result in unwarranted hard drive replacement.
When HP workstations are built, each installed hard drive is tested using DPS, and a permanent record of
key information is written onto the drive. Each time DPS is run, test results are written to the hard drive. The
service provider can use this information to help diagnose conditions that caused you to run the DPS
software.

ECC Fault Prediction and Prefailure Warranty

When the workstation encounters an excessive number of error checking and correcting (ECC) memory
errors, the workstation displays a Local Alert message. This message contains detailed information about
the errant memory module, allowing you to take action before you experience non-correctable memory
errors. The Prefailure Warranty for ECC memory modules allows you to replace these modules, free of
charge, before the modules actually fail. ECC memory modules are optional on selected HP systems.
NOTE: To use this feature, you must replace the standard DIMMs with HP ECC DIMMs.

Surge-Tolerant Power Supply

An integrated surge-tolerant power supply provides greater reliability when the workstation is hit with an
unpredictable power surge. This power supply is rated to withstand a power surge of up to 2000V (Line to
PE or Neutral to PE) and 1000V (Line to Line) without any data loss or system downtime.

Thermal Sensor

The thermal sensor is a hardware and software feature that tracks the internal temperature of the
workstation. When combined with HP Client Manager Software, this features notifies the network
administrator when the normal range is exceeded.
The thermal sensor monitors the processor temperature. If the temperature does not go down, then the
system eventually shuts down.
