Cable Lock (Optional); Fault Notification And Recovery; Drive Protection System; Ecc Fault Prediction - HP Z400 Maintenance And Service Manual

Cable lock (optional)

To prevent theft, the rear chassis panel of the workstation accommodates a keyed cable lock. This cable
lock attaches to the chassis and secures it to the work area.

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 that is managed by HP CMS, the workstation sends a fault
notice to the network management application. With HP CMS, you can also remotely schedule
diagnostics to run on managed PCs and create a summary report of failed tests.

Drive Protection System

The Drive Protection System (DPS) is a diagnostic tool built into hard disk drives and is installed in select
HP workstations. The DPS helps diagnose problems that might result in unwarranted hard disk drive
replacement.
When HP workstations are built, each installed hard disk drive is tested using the DPS, and a
permanent record of key information is written onto each drive. Every time the DPS is run, test results
are written to the hard disk drive. The service provider can use this information to help diagnose
conditions that required you to run the DPS software.

ECC fault prediction

When the workstation encounters an excessive number of error checking and correcting (ECC) memory
errors, it displays a local alert message. This message contains information about the errant DIMM,
enabling you to take action before you experience noncorrectable memory errors. ECC DIMMs are
standard on this workstation.

Thermal sensors

Several thermal sensors in the HP Workstation regulate workstation fans to maintain an acceptable,
efficient chassis temperature.
