1.8.1 V.24 interface (external management)
A serial interface is provided on the RJ45 socket (V.24 interface) for the local
connection of an external management station (VT100 terminal or PC with
corresponding terminal emulation). This enables you to set up a connection
to the Command Line Interface CLI and to the system monitor.
The socket housing is electrically connected to the front panel of the device.
The V.24 interface is electrically insulated from the supply voltage.
Note: The Terminal cable is available as an accessory.
See “Accessories” on page 54.
1.8.2 USB interface
The USB interface allows you to connect the AutoConfiguration Adapter
ACA21 storage medium. This is used for saving/loading the configuration
data and diagnostic information, and for loading the software.
For information about the position on the device see “Front view” on page 21.
On the front of the device there is an LED display that informs you about the
status of the interface.
