The SCALANCE X-300 Industrial Ethernet switches with their robust metal enclosure are optimized for mounting on a standard DIN rail and the S7-300 mounting rail. Direct wall mounting in different positions is also possible. Due to the S7-300 enclosure dimensions, the devices are ideally suited for integration in an automation system using S7-300 components.

The switches have:

• 4-pin terminal block for connection of the redundant power supply (2 x 24 V DC)
• Row of LEDs for indicating status information (power, link status, data transfer, error indication, redundancy manager, standby manager)
• 2-pin terminal block for connecting the isolated signaling contact
• SELECT/SET pushbutton for on-site configuration of the signaling contact
• Slot for optional C-PLUG swap medium on the rear of the device for the easy replacement of the device in the event of a fault
• SCALANCE X308-2M PoE has four integrated electrical, PoE-compatible Ethernet ports and two slots for accommodating 2-port media modules
