Fault Notification And Recovery - HP Xw8200 - Workstation - 1 GB RAM Technical Reference Manual

Hood Sensor (Smart Cover Sensor)
This sensor is set in the Computer Setup utility. You can set this to notify a user if the access panel has
been removed.
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 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. 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.
Ultra ATA Integrity Monitoring
Ultra ATA Integrity Monitoring monitors the integrity of data as it is transferred between an Ultra ATA hard
drive and the system's core logic. If the workstation detects an abnormal number of transmission errors,
the workstation displays a Local Alert message with recommended actions.
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 2000 V (Line
to PE or Neutral to PE) and 1000 V (Line to Line) without any data loss or system downtime.
