V.24 interface (external management)
A serial interface is provided on the RJ11 socket (V.24 interface) for the
local connection of an external management station (VT100 terminal or
PC with appropriate terminal emulation) or an AutoConfiguration Adapter
ACA 11. This enables a connection to the Command Line Interface (CLI)
and the system monitor to be made.
The socket housing is electrically connected to the front panel of the
device. The V24 interface is not electrically isolated from the supply
voltage.

Note: You will find the order number for the terminal cable, which is
ordered separately, in the Technical Data chapter (see on page 52
“Technical data”).
Monitoring the ambient air temperature
Only operate the device up to the specified maximum ambient air
temperature.
See “General technical data” on page 52.
The ambient air temperature is the temperature of the air at a distance of
5 cm from the device. It depends on the installation conditions of the
device, e.g. the distance from other devices or other objects, and the
output of neighboring devices.
The temperature displayed in the CLI and the GUI is the inner
temperature of the device. It is up to 20 °C higher than the ambient
temperature. This depends on the configuration of your device.
