Industrial Gigabit Switch for Harsh Environments
The Black Box LIG401A is an unmanaged industrial Ethernet switch built for deployment in factories, oil and gas fields, military vehicles, and HVAC or security systems. It provides four RJ-45 ports with 10/100/1000 Mbps auto-negotiation and one 100/1000BASE-SFP slot for fiber uplinks. The fanless, IP30-rated housing operates from -40 to 75 degrees Celsius and supports DIN rail or wall mounting for flexible installation in tight spaces.
Sustained Load Behaviour
A 128 KB buffer and a 2000-entry MAC address table handle continuous traffic without head-of-line blocking, while 9000-byte jumbo frame support reduces overhead on large data transfers. Quality of Service prioritises time-sensitive streams such as surveillance video or control signals during congestion. Dual redundant 12 to 58 V DC inputs with reverse polarity protection keep the switch running if one supply fails, and an alarm relay signals the fault immediately.
Pre-Installation Checks
Verify that your site provides 12 to 58 V DC power and that you have wiring for the dual terminal blocks to enable redundancy. Confirm the SFP module you select matches the required fiber type and distance, noting that Black Box SFPs are recommended for compatibility. Ensure the mounting surface accommodates the 4.4 by 1.1 by 3.5 inch footprint and that ambient temperature stays within the -40 to 75 degree Celsius operating range.

Questions about this item
Does the fanless IP30 enclosure stay cool when the switch runs continuously at 75 °C ambient?
Yes, the fanless design is rated for continuous operation up to 75 °C with no moving parts to fail.
What DC voltage sources do I need to power the dual redundant inputs?
Two independent 12-58 V DC supplies connect to the terminal block for automatic fail-over.
Will my existing 100 Mbps SFP module work in the Gigabit SFP slot?
The slot accepts 100/1000BASE SFP modules, so a 100 Mbps module will link at 100 Mbps.
