Access panel key lock This lock prevents removal of the access panel and all internal components. The key is shipped on the rear of the workstation. 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, it displays a Local Alert message. This message contains detailed information about the errant memory module, enabling you to take action before you experience un-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 supported on current HP workstations. Thermal sensors A thermal sensor is a hardware and software feature that tracks temperature. When combined with HP Client Manager Software, a thermal sensor notifies the network administrator when a normal temperature range is exceeded. For example, a thermal sensor monitors processor temperature. If processor temperature remains too high, the system eventually shuts down. ENWW Desktop management 49
