2.1Properties, 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.
