Ecc Fault Prediction And Prefailure Warranty; Thermal Sensor - HP xw4300 Service And Technical Reference Manual

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 sensors are hardware and software features that track the internal temperature of the workstation. Based on
those readings, the sensors influence the speed of the internal fans. The sensors can also cause the system to execute
slowly or shut down when predetermined temperature limits are exceeded. When combined with HP Client Manager
Software, this feature notifies the network administrator when the normal range is exceeded.
