Deployment / Use Cases
This switch excels in industrial automation environments where reliable networking must coexist with machinery, motors, and harsh conditions. Its PoE+ capability powers surveillance cameras and access points throughout manufacturing facilities while the SFP slots connect to fiber backbones spanning long distances between buildings.
Transportation networks deploy these switches in rail signaling systems, toll collection points, or airport baggage handling where vibration resistance and consistent performance are critical. The hardened construction also suits outdoor installations in weather-protected enclosures for traffic management systems, remote monitoring stations, or renewable energy facilities.
Industrial IoT Networks
Connects sensors, controllers, and HMIs across production lines with PoE for simplified wiring and managed switching for traffic control.
Critical Infrastructure
Provides reliable connectivity for security systems, access control, and monitoring equipment in utilities, transportation, and public safety applications.
Physical Profile
The switch measures 2.85" (72.39 mm) in height, 6.80" (172.72 mm) in width, and 5.60" (142.24 mm) in depth, with a weight of approximately 3.74 lb (1696.44 g). This compact footprint fits standard DIN rail enclosures or 19-inch rack shelves while leaving space for cable management and ventilation. The environmentally friendly construction meets industrial standards for durability and sustainability.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 2.85" (72.39 mm), 6.80" (172.72 mm), 5.60" (142.24 mm), 3.74 lb (1696.44 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

FAQ
How many PoE+ ports does this switch have and what power do they deliver?
The Black Box LEH1104A-2GSFP has four Fast Ethernet ports with PoE+ capability. These ports comply with IEEE 802.3at standards, delivering up to 30W per port to power devices such as IP cameras, wireless access points, VoIP phones, or sensors without requiring separate power supplies at each endpoint.
What types of SFP modules are compatible with the two expansion slots?
The two Gigabit SFP slots support standard SFP modules for both copper and fiber connections. You can use 1000Base-T copper SFPs for twisted pair connections up to 100 meters, or 1000Base-X fiber SFPs for single-mode or multi-mode fiber connections, providing flexibility for different distance requirements and media types in your network backbone.
Is this switch manageable and what Layer does it support?
Yes, this is a fully manageable Layer 2 switch. It supports standard management protocols for configuration, monitoring, and diagnostics. Layer 2 features include VLANs for network segmentation, QoS for traffic prioritization, and security functions like port security and storm control, providing enterprise-grade network control in an industrial form factor.
What mounting options are available for installation?
The switch offers three mounting options: DIN rail mounting for industrial control panels, 19-inch rack mounting for standard network racks, and panel mounting for enclosure integration.
