Deployment / Use Cases
This industrial switch is ideal for environments requiring reliable Ethernet connectivity in challenging conditions. Its rugged design and wide operating temperature range make it suitable for manufacturing floors, outdoor enclosures, transportation systems, and utility installations.
The combination of copper and fiber connectivity options allows flexible network design. Use the RJ-45 ports for local device connections while employing the SFP uplink for backbone connections to network cores or for spanning longer distances where copper would be impractical.
Industrial Automation
Connect PLCs, HMIs, sensors, and control devices on factory floors where temperature extremes, vibration, and particulate contamination are common challenges.
Outdoor & Harsh Environments
Deploy in weatherproof enclosures for traffic control systems, remote monitoring stations, or agricultural applications where temperature fluctuations exceed commercial equipment specifications.
Physical Profile
The switch's compact dimensions (4.40" × 1.10" × 3.50") and lightweight design (11.20 oz) facilitate installation in space-constrained locations. The industrial gray finish and sturdy construction withstand physical stress in demanding environments. Both DIN rail and wall mounting hardware are included, providing installation flexibility without additional purchases.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 4.40" (111.76 mm), 1.10" (27.94 mm), 3.50" (88.90 mm), 11.20 oz (317.51 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

User Manual
FAQ
How many network ports does this switch have?
The Black Box LIG401A provides four 10/100/1000BASE-T RJ-45 Gigabit Ethernet ports for connecting network devices. Additionally, it includes one SFP (Small Form-factor Pluggable) slot that serves as an uplink port, supporting either fiber or copper SFP modules for network expansion or longer-distance connections.
Is this a managed or unmanaged switch?
This is an unmanaged Layer 2 Ethernet switch, meaning it operates as a plug-and-play device without configuration interfaces or advanced management features. It automatically negotiates connections and forwards traffic between ports, making it ideal for simple network segments where basic connectivity is the primary requirement.
What temperature range can this switch operate in?
The industrial design supports operation in extreme temperatures from -40°F to +167°F (-40°C to +75°C). This wide range allows deployment in unheated outdoor enclosures, refrigerated spaces, or hot industrial environments where standard commercial switches would fail due to temperature limitations.
Does this switch support Power over Ethernet (PoE)?
No, the LIG401A does not provide Power over Ethernet functionality. While it complies with IEEE 802.3af and 802.3at standards for interoperability, it cannot deliver power to connected devices via the Ethernet ports. Connected devices must have their own power sources.
What mounting options are available for this switch?
The switch supports both DIN rail and wall mounting. The package includes a DIN rail clip for standard 35mm DIN rail installation commonly used in industrial control panels, plus two wall mount plates with hardware for direct surface mounting. The compact dimensions allow installation in space-constrained locations.
What type of power input does this switch require?
The switch accepts 12-58 V DC power input through the included terminal block. This wide voltage range provides flexibility for integration with various industrial power systems, including 12V, 24V, or 48V DC sources commonly found in industrial and transportation applications.
