The mechanical and electrical steps involved in replacing the PCU hard disk are described
in:

Commissioning a replacement hard disk
After installing the replacement hard disk, the Ethernet interfaces of the PCU are preset in
the following manner:
● Ethernet 1 (Company Network) as a standard DHCP client
● Ethernet 2 (System Network) as a SINUMERIK DHCP server with the fixed IP address
The PCU must therefore be disconnected from the system network before the replacement
hard disk is fitted.
Download a hard disk back-up (disk image) to commission the replacement hard disk.
Please proceed as follows:
1. Connect a PG/PC as per the recommended configurations.
2. Start the ServiceCenter and select "Restore Disk Image".

Note
If the transfer is interrupted during the "Restore" process, no consistent system is
available on the hard disk, i.e. the "Restore" process cannot be repeated because the
PCU no longer boots up.
In this event, the "Emergency Boot System" is used.
