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.
When a fault occurs, the computer displays a Local Alert message containing a description of the
fault and any recommended actions. You can then view current system health by using Compaq
Insight Personal Edition. If the computer is connected to a network managed by Compaq Insight
Manager or other SNMP-based management products from Compaq Management Solutions
Partners, the computer also sends a fault notice to the network management application.
2.10.1

Pentium II Fault Prediction and Prefailure Warranty

When the processor encounters an excessive number of error checking and correcting (ECC)
cache memory errors, the computer displays a Local Alert Message. This message contains
detailed information about the faulty processor, allowing your to take action before you
experience non-correctable cache memory errors. The Prefailure Warranty allows you to replace
these processors, free of charge, before they actually fail. Processors with ECC cache memory are
available on select Compaq personal computers.
2.10.2

SMART Hard Drive Fault Prediction

The SMART hard drive monitors hard drive activity to predict failures and, in some cases, fix
faults before failures occur. Fault prediction and failure indication parameters, such as abnormal
variations in spinup and seek times, or non-correctable read and write errors, are tracked to
determine the hard drive condition. Should these errors become significant, the computer displays
a warning message. The warning gives you time to back up the hard drive and replace it prior to
experiencing downtime or loss of data. The Prefailure Warranty for SMART hard drives allows
you to replace these drives, free of charge, before the drives fail.
SMART hard drives are compliant with the Small Form Factor Committee Specification for Self-
Monitoring, Analysis, and Reporting Technology (SMART). SMART is the industry standard
technology, pioneered by Compaq and originally called IntelliSafe, that allows you to prevent data
loss and minimize downtime, in concert with Compaq Insight Management Agents.
2.10.3

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 computer detects an abnormal number of
transmission errors, the computer displays a Local Alert message with recommended actions. An
alert is also sent over the network to the system administrator.
2.10.4

ECC Fault Prediction and Prefailure Warranty

When the computer encounters an excessive number of error checking and correcting (ECC)
memory errors, the computer 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 all Compaq personal computers.
To use this feature, you must replace the standard DIMMs with ECC DIMMs.
