Installation MS20/MS30
Release 13 09/2019
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
ACA11. 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 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 section
(see on page 62
.
Monitoring the ambient air temperature
Operate the device below the specified maximum ambient air
temperature exclusively.
See “General technical data” on page 62.
The ambient air temperature is the temperature of the air at a distance of
2 in (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 internal
temperature of the device. It is up to 68 °F (20 °C) higher than the ambient
temperature. This depends on the configuration of your device.
