The SCALANCE XR-500 Industrial Ethernet switches with robust metal enclosure with IP20 degree of protection are optimized for installation in the 19" control cabinet. The power supply unit (85 to 264 V AC) for power supply to the SCALANCE XR-500, which is also optimized for the 19" cabinet, can either be installed directly at the back of the SCALANCE XR522/XR528, or connected using connecting cables (installation of the power supply unit in a 19" rack). The data ports of the SCALANCE XR-500 are located optionally either at the front or rear of the device (depending on the device variant).

The switches have:

• 4-pole terminal block on the front for connecting the optionally available power supply unit (85 V to 264 V AC)
• 6-pole connector for assembly of the optionally available power supply unit (85 V to 264 V AC) on the rear
• 2-pole 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 on the side of the device for the C-PLUG swap medium for simple device replacement in the event of a fault, or for the KEY-PLUG for adding IP routing to the device functionality
• Console port (RS 232 serial interface, RJ11 cable to Sub-D (9-pole) included in scope of delivery) and management port (Ethernet interface) for on-site parameter assignment/diagnostics

The SCALANCE XR-500 switches are available with the following types of port depending on the device variant:

• Four SFP+ slots for optical SFP+ or SFP plug-in transceivers (multimode and singlemode connections)
  • The SFP+ plug-in transceivers support 10 Gbps
  • The SFP plug-in transceivers support 1000 Mbps
• Up to 12 slots for electrical 4-port media modules and electrical PoE 4-port media modules or optical 4-port media modules for multimode or singlemode connections; the optical media modules are available in various connection technologies
  • The RJ45 sockets are also available in industry-standard design 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
