Connecting peripherals

5.3.1
Overview
When connecting the device for the first time, connect a PS/2 keyboard and PS/2 mouse.
Connect any required USB components such as a USB hub.
Caution
Disconnect the device from the power supply before connecting peripherals. This does not
apply to connecting and disconnecting USB devices.
Connect only I/O modules approved for industrial applications according to EN 61000-6-
2:2001. Use shielded cables and metal connectors to connect peripherals. Otherwise, the
specified standards and specifications declared by Siemens AG are no longer valid. Secure
the plugs of the interface cables to the device housing with screws. This improves the
electrical shielding.
Mouse
Connect a PS/2 or USB mouse.
5.3.2
Connecting a monitor
The front panel is activated as the display by default when the operating system starts. An
external monitor connected to the VGA port is therefore deactivated.
Learn how to activate an external monitor by reading the section "Installing and removing
hardware components" in the "Service and maintenance" chapter.
