2.1 Properties, Functionality and Features of
SCALANCE X-400
This chapter explains special properties, features and options available to you with
the SCALANCE X-400 product line.
The basic device consists of the frame, the power supply, digital inputs and a
Switch CPU.
SCALANCE X-400 provides a modular structure for the required ports. This modu-
larity simplifies setup and subsequent expansion of complex network topologies to
meet current needs.
● Gigabit technology
The basic device has ports with a transmission rate of 1 Gbps for electrical ca-
bles (twisted pair) or by adding a gigabit media module for fiber-optic cables
(FO).
● With SCALANCE X-400, it is possible to split the ring ports into two different
slots (fast Ethernet module - slots 6 and 7). If one of the media modules fails,
operation can be maintained as a line structure. A defective module can be re-
placed during operation.
● Diagnostics
Remote diagnostic options are available with Web-based management, TelNet,
or SNMP.
● The basic device has a signaling contact for local operator control.
● An Ethernet interface is available for diagnostics and management purposes.
