The SCALANCE XR-300EEC Industrial Ethernet switches with rugged metal enclosure with IP20 degree of protection are optimized for installation in the 19" cabinet.

The switches have:

• 4-pin terminal block for redundant voltage feed for protection against voltage failure in 24 V DC version
• 3-pin terminal block for voltage feed in 230 V AC version
• 2-pin terminal block for connecting the isolated signaling contact for simple display of faults
• A row of LEDs to indicate the status information (power, link status, data traffic, power supply, signaling contact)
• SELECT/SET pushbutton for simple adjustment of the fault signaling contact on the device
• Slot for optional C-PLUG swap medium on the side of the device for easy replacement in the event of a fault
• Console port (serial interface) for on-site parameterization/diagnostics (RJ11 cable to RS232 (9-pin) included in scope of delivery)

The SCALANCE XR-300EEC switches are available with the following port types:

• 16 integrated RJ45 ports;
  The RJ45 sockets are designed to be industry-compatible with additional sleeves, for connection of the Industrial Ethernet FC RJ45 Plug 180
• Four slots for electrical or optical 2-port media modules for multimode or single-mode connections; the optical media modules are available in various connection technologies
• All electrical Ethernet interfaces support 10/100/1000 Mbit/s,
  all optical Ethernet interfaces support 100 or 1000 Mbit/s
• The SCALANCE XR-300EEC switches support Gigabit Ethernet (1000 Mbit/s) at all ports.
  The 24 ports are divided into three groups of eight ports each (Gigabit Ethernet Blocking). Gigabit Ethernet is supported with full wire speed within each group, but not between the groups.
