The SCALANCE X-300EEC Industrial Ethernet switches with rugged metal enclosure are optimized for mounting on a standard DIN rail. Thanks to the enclosure dimension 19"/2 (internal dimension), two devices can be mounted side by side in a 19" cabinet.

The switches have:

• a 4-pin terminal block for connecting the redundant power supply (2 x 24 V DC)
• A 2-pin terminal block for connecting the isolated signaling contact
• A row of LEDs to indicate the status information (power, link status, data traffic, power supply, signaling contact)
• SELECT/SET key for on-site configuration of the signaling contact
• Slot for optional C-PLUG swap medium on the top of the device for easy replacement in the event of a fault
• Guide rails for strain-relief attachment of the RJ45 and LC connection to the switch

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

• As many as seven integrated fiber-optic ports for connecting the SCALANCE X switches with one another (multimode). The Fast Ethernet fiber optic ports are designed using LC connection technology.
• Up to seven integrated twisted pair ports;
  the RJ45 sockets are designed to be industry-compatible with additional retaining mechanisms, for connection of the Industrial Ethernet FC RJ45 Plug 180.
