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 Drive Protection System (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 pre-failure 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, enabling you to take action before you experience non-correctable memory errors. The pre-failure warranty for ECC memory modules enables you to replace these modules, free of charge, before the modules actually fail. ECC memory modules are optional on selected HP systems. Thermal sensor There are multiple sensors on your workstation: ● One per processor ● One per memory module (DIMM) ● One for the system board ● Some hard drives The processor 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. In this case, the processor clock automatically begins to throttle. If the temperature does not decrease, the system eventually shuts down. 44 Chapter 3 System management ENWW

There are multiple sensors on your workstation:

One per memory module (DIMM)
●
One for the system board
