Switch unmanaged Barox PC-IA402-S

The Barox PC-IA402-S is an unmanaged L2 Fast Ethernet switch with four 10/100TX RJ-45 ports and two SFP slots for fibre connections. Built with a high backplane capacity and a MAC address table of 1024 entries, the device supports efficient traffic handling in demanding networks. It complies with IEEE 802.3 standards, accepts a wide DC input range of 9–56 V, is supplied in black, and can be mounted on a wall or DIN rail for outdoor or industrial installations.

Advantages

The switch provides five to eight-port-style connectivity by combining four copper ports and two SFP fibre uplinks, delivering a total switching capacity of 1.2 Gbit/s. Its robust industrial design and wide voltage input make it suitable for installations with fluctuating power and for outdoor or harsh environments. The unmanaged L2 operation simplifies deployment without requiring configuration, while the SFP bays allow multimode or singlemode fibre modules for flexible uplink distances.

Suitable for

• Video surveillance systems and high-traffic camera networks
• Industrial automation and control networks
• Outdoor and wall- or DIN-rail-mounted network segments
• Short to long-distance uplinks using multimode or singlemode fibre

How to use

Install the Barox PC-IA402-S on a wall or DIN rail following the manufacturer's mounting instructions and connect the DC power source within the 9–56 V range. Plug Ethernet devices into the RJ-45 ports and insert appropriate SFP fibre modules (multimode or singlemode) into the SFP slots for uplink connections. As an unmanaged L2 switch, it operates without configuration; connected devices will negotiate link speed and duplex automatically according to IEEE 802.3 standards.

Recommendations

For reliable operation in surveillance or industrial environments, use shielded Ethernet cables where required, choose SFP modules that match your fibre type and distance, and ensure a stable DC supply within the specified voltage range. Avoid locating the unit in areas with excessive heat or moisture beyond outdoor-rated installation guidelines.
