Industrial Switch ROLINE 21.13.1154 6x RJ-45 2x SC unmanaged

The ROLINE Industrial Switch 21.13.1154 is an unmanaged Fast Ethernet switch designed for industrial network environments. It provides six 10/100Base-T RJ-45 ports and two 100Base-FX SC fiber ports, offering wire-speed store-and-forward switching and support for full- and half-duplex flow control. The unit accepts 7–30 V DC input via a terminal block or a 6.3 mm/2.0 mm DC jack and is suitable for DIN-rail mounting in temperature-critical installations.

Advantages

This industrial switch delivers reliable, industrial-rated emission and immunity performance and maintains stable operation across a wide temperature range (-20 °C to +70 °C). It supports IEEE 802.3x flow control for full-duplex links and back-pressure flow control for half-duplex links, ensuring efficient traffic handling. The compact metal housing and DIN-rail mounting option simplify installation in control cabinets and other constrained spaces.

Suitable for

• Factory automation networks
• Transport and surveillance systems requiring fiber uplinks
• Industrial control cabinets and field installations
• Small to medium-sized Ethernet segment extension with fiber reach

How to use

Mount the switch on a DIN rail and connect the DC power source to the terminal block or the 6.3 mm/2.0 mm DC jack, ensuring the supply voltage is within 7–30 V DC. Connect copper devices to the RJ-45 ports and fiber links to the SC ports. The unmanaged switch operates without configuration; connected devices will negotiate link speed and duplex according to IEEE standards and flow control will be handled automatically.

Recommendations

Install the switch in a ventilated enclosure and avoid placing it near strong electromagnetic interference sources. Use the recommended power supply (21.13.1226) to ensure stable operation and verify fiber connector cleanliness before establishing fiber links.
