General information and networking
4.3 Networking
Obtaining user authorization
On a TCU that has no user authorization, the first key that is pressed serves exclusively to request
the user authorization, i.e. this key is not evaluated by the operating software.
The settings for the right to veto are stored in file tcu.ini and are only effective if the
operating software is installed on the PCU. At the OP of the TCU, the operating software can
be operated in exactly the same way as an OP directly connected to the PCU.
Note
These operator input sequence steps must only be carried out by qualified personnel!

Example: Distributing boot support across two PCUs
To distribute boot support over two PCUs, "Boot support runtime and configuration only (TFTP/
FTP)" must be selected on PCU_1 and "Boot support IP address only (DHCP)" must be selected on
PCU_2.
The "No boot support" configuration must be selected on PCU_3:

connected TCUs. PCU_3 is not involved in booting the TCUs, it is however displayed by the
TCUs using VNC.
