Cable lock (optional)

To prevent theft, you can attach a keyed cable lock to the bottom-left corner of the chassis. 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 computer is connected to a network that is managed by HP CMS, the computer 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.

ECC fault prediction

When the computer 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 computer.

Thermal sensors

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

Dual-state power button

With ACPI enabled, the power button can function as an on/off switch or as a button. This feature does not
completely turn off power, but instead causes the computer to enter a low-power standby state. This
enables you to go to standby without closing applications, and to return to the same operational state
without any data loss.
