8.3 Hard Disk
8.3.1 General Information
WARNING
Loss of data!
All required application data as well as operating system settings are to be
backed up on an external data carrier!
WARNING
Damages on the VSB 40.3 due to electrostatic discharges!
Comply with all ESD protective measures while working with modules and
components! Avoid electrostatic discharges!
To store user data and to avoid the reinstallation of the operating
system and application programs after a hard disk exchange, back‐
up the well-working hard disk at regular intervals.
The hard disk to be inserted must already be provided with an in‐
stalled operating system, if no external boot medium is connected
to the control cabinet PC! In any case, we recommend you to have
a completely installed operating system on the hard disk to shorten
the installation time!
8.3.2 Exchanging the Hard Disk of the VSB 40.3
1. All required user data as well as the operating system settings of your
system are to be stored either on an external storage medium or via the
network connection! For the back up, see also chapter 9 "Software" on
page 55.
2. Switch off the supply voltage.
3. Wait until the power supply unit switches off automatically after the UPS
operation.
4. Ensure that no voltage is in the control cabinet PC. Disconnect the PC
power supply from the X10 connection, if required, see "24 VDC voltage
supply" on page 38.
