Installation and Setup
NOTICE
Please verify that cables, interfaces, and handling of the devices comply with the requirements (see chapter 8,
page 47).
First-time users are recommended to set up the system in a test environment that is limited to a single room. This
makes it easier to identify and solve any cabling problems, and experiment with your system more conveniently.
Add-on modules installed in the chassis can be hot plugged.
The chassis configuration determined by customer configuration is delivered accordingly with the initial order.
Installation by the customer is not intended and not necessary. In case of an extender module or add-on module
replacement, please refer to the installation instructions in the 474-BODY manual.
