The SCALANCE XR-300 Industrial Ethernet switches with rugged metal enclosure with IP30 degree of protection are optimized for installation in the 19" control cabinet. Versions are available with 24 V DC or 230 V AC connection. The connection of the power supply and the data cable outlet are located optionally either at the front or rear of the device.

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
• Row of LEDs for indicating status information (power, link status, data transfer, power supply, signaling contact)
• SELECT/SET pushbutton for easy setting 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-300 switches are available with the following port types:

• 12 slots for electrical or optical 2-port media modules for multi-mode or single-mode connections; the optical media modules are available in various connection technologies
• The RJ45 sockets are designed to be industry-compatible with additional sleeves, for connection of the Industrial Ethernet FC RJ45 Plug 180
• All electrical Ethernet interfaces support 10/100/1000 Mbit/s,
  all optical Ethernet interfaces support 100 or 1000 Mbit/s
• The SCALANCE XR-300 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.
