HP Z230 Workstation - Maintenance and Service Guide

Side access panel solenoid lock
The side access panel solenoid lock (available only on specific workstations) secures the side access panel to
the chassis. The solenoid is controlled by a local or remote signal.
To lock the solenoid, set a password for the solenoid lock in Computer Setup (f10) Utility. To unlock the
solenoid, remove the solenoid lock password in Computer Setup (f10) Utility.
The solenoid lock FailSafe Key (available from HP) is is a device for manually disabling the solenoid lock. You
will need the FailSafe Key in case of a forgotten password, power loss, or computer malfunction.
Cable lock (optional)
To prevent theft, you can attach a keyed cable lock to the rear chassis panel. 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.
