2.11.2 Fault Management
Fault Management 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 simple network management protocol (SNMP)–based management products (e.g.,
HP OpenView or IBM Tivoli TME10 NetView), the computer also sends a fault notice to the
network management application.
SMART II Hard Drive Fault Prediction
The SMART II hard drive monitors hard drive activity to predict failures before they 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 II hard drives allows you to replace these drives, free of charge, before the
drives fail.
SMART II hard drives are compliant with the Small Form Factor Committee Specification for Self-
Monitoring, Analysis, and Reporting Technology (SMART) Version II. 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.
ECC Fault Prediction and Prefailure Warranty
When the computer encounters an excessive number of error checking and correcting (ECC) memory
errors, the screen 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 Deskpro personal computers.
✎
To use this feature, you must replace the standard DIMMs with ECC DIMMs.
Monitor Fault Diagnosis
New Compaq monitors detect when the operating temperature exceeds the normal range or when a
hardware fault occurs. Hardware faults may include the following:
■
Power voltage out of range
■
Power current out of range
■
Horizontal deflection
■
Vertical deflection
■
I/O controller operation failure
