"admin" and "" before you operate the device.
To prevent unauthorized access, note the following security recommendations.
General
●You should make regular checks to make sure that the device meets these
recommendations and/or other security guidelines.
●Evaluate your plant as a whole in terms of security. Use a cell protection concept with
suitable products (https://www.industry.siemens.com/topics/global/en/industrial-
security/pages/default.aspx).
●When the internal and external network are disconnected, an attacker cannot access
internal data from the outside. Therefore operate the device only within a protected
network area.
●For communication via non-secure networks use additional devices with VPN functionality
to encrypt and authenticate the communication.
●Terminate management connections correctly (WBM. Telnet, SSH etc.).
Physical access
●Restrict physical access to the device to qualified personnel.
–The memory card or the PLUG (C-PLUG, KEY-PLUG) contains sensitive data such as
certificates, keys etc. that can be read out and modified.
–Using the button, you can reset the device to the factory defaults.
●If the device is publicly accessible, disable the functions of the button using the software.

–SNMPv1/v2c →SNMPv3
Check whether use of SNMPv1/v2c. is necessary. SNMPv1/v2c is classified as non-
secure. Use the option of preventing write access. The device provides you with
suitable setting options.
If SNMP is enabled, change the community names. If no unrestricted access is
necessary, restrict access with SNMP.
Use the authentication and encryption mechanisms of SNMPv3.
●Use secure protocols when access to the device is not prevented by physical protection
measures.
●If you require non-secure protocols and services, operate the device only within a
protected network area.
●Restrict the services and protocols available to the outside to a minimum.
●For the DCP function, enable the "Read Only" mode after commissioning.
●If you use RADIUS for management access to the device, activate secure protocols and
services.

Properties and functions
SCALANCE XM-400 product group
The product group SCALANCE XM-400 consists of basic devices (compact switches) and
extenders (port extenders and function extender).
SCALANCE XM-400 basic device
Basic properties
The SCALANCE XM-400 basic devices are modular compact switches with fixed RJ-45
ports (10/100/1000 Mbps) and SFP transceiver slots that can be equipped individually. The
SFP transceiver slots are combo ports.
A SCALANCE XM-400 can manage a maximum of 24 ports with 10/100/1000 Mbps.
The following components exist only on the basic device:
●CPU
●Power supply
●Signaling contact
●Out-of-band port
●Serial interface
●"SELECT / SET" button
Expansions
The basic devices can be expanded with additional ports and functions by using an
extender. The extenders are connected to the side of the basic device. Each basic device
has an expansion interface to the left for function extenders and to the right an expansion
interface for port extenders.
Depending on the number of ports of the basic device (10/100/1000 Mbps) up to 2 port
extenders can be added. Further port extenders are not supplied with power. There is no
particular order in which the port extenders need to be added.
Example:
●The basic device SCALANCE XM408-8C has 8 ports. It can therefore be expanded by 2
port extenders each with 8 ports.
●The basic device SCALANCE XM416-4C has 16 ports. It can therefore be expanded by
one port extender with 8 ports.
A function extender can be added.
