The Backbone switches in the MACH4000 family are equipped with 8 or 16 Gigabit Ethernet ports as standard. By adding additional hot-swappable 8-port media modules, the port density can be increased to 24 or 48. Depending on the model of switch (5 versions available), three 10 Gigabit interfaces are also provided.
Further features of these backbone switches include various routing functions, comprehensive management and redundancy methods, as well as numerous security mechanisms. A USB interface can be used for connection to the ACA 21 auto-configuration adapter, which can be used to save all configuration data as well as to conveniently upgrade the operating system. Due to their robust design,

the MACH4000 switches can withstand shocks and vibrations, magnetic fields and electrostatic discharges. The switches also boast a number of industryspecific certifications, making them suitable for use in such areas as transformer substations (IEC 61850), railways (EN 50121-4), and onboard ships (GL).
