The SCALANCE XR-300PoE Industrial Ethernet switches with rugged metal enclosure with IP20 degree of protection are optimized for installation in the 19" control cabinet. Versions are available with either 24 V DC or 100 - 240 V AC connections. 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 to protect against power failure with 24 V DC
• 2-pin terminal block for voltage feed with 100 - 240 V AC
• 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 traffic, 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 of the device 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-300PoE switches are available with the following types of port:

• 16 integrated RJ45 ports, eight RJ45 ports supporting PoE;
• The RJ45 sockets are designed to be industry-compatible with additional retaining collars for connection of the Industrial Ethernet FC RJ45 Plug 180
• All electrical Ethernet interfaces support 10/100/1000 Mbps,
  all optical Ethernet interfaces support 100 or 1000 Mbps
• The SCALANCE XR-300 switches support Gigabit Ethernet (1000 Mbps) 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.
