Product Features
Technical Overview
The LBH3080A operates as a Layer 2 switch with eight 10/100Base-T RJ-45 ports that automatically negotiate speed and duplex settings. Each port supports auto MDI/MDI-X crossover detection, eliminating the need for special crossover cables and simplifying installation.
This switch uses store-and-forward switching with a non-blocking architecture to maintain full wire-speed performance across all ports. It incorporates broadcast storm protection to prevent network degradation from excessive broadcast traffic, enhancing overall network stability.

Industrial Automation
Connects PLCs, HMIs, and industrial controllers on factory floors, oil/gas facilities, and processing plants where temperature extremes and vibration are common.
Remote Infrastructure
Networks equipment in telecommunications huts, transportation systems, military installations, and utility substations where environmental control is limited.
Physical Profile
The LBH3080A features a compact industrial design measuring 5.51" high × 1.18" wide × 3.74" deep (139.95 × 29.97 × 95 mm) and weighing approximately 1 lb (453.59 g). Its slim profile allows installation in space-constrained DIN rail enclosures or directly on walls using the included mounting hardware.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 5.51" (139.95 mm), 1.18" (29.97 mm), 3.74" (95 mm), 1 lb (453.59 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

User Manual
FAQ
How many Ethernet ports does the LBH3080A switch have?
The Black Box LBH3080A features eight Fast Ethernet (10/100Base-T) RJ-45 ports. All ports support auto-negotiation for speed and duplex settings, along with auto MDI/MDI-X crossover detection, eliminating the need for special crossover cables during installation.
What temperature range can this industrial switch withstand?
This switch is rated for operation in extreme temperatures from -40°F to +167°F (-40°C to +75°C). This wide operating range makes it suitable for deployment in unheated warehouses, outdoor enclosures, industrial facilities, and other environments where commercial switches would fail.
Can this switch be mounted in industrial control panels?
Yes, the LBH3080A supports multiple mounting options including DIN rail, wall, and panel mounting. The switch includes a panel mount kit for flexible installation in industrial cabinets, control panels, or equipment racks where space is constrained.
Does this switch support Power over Ethernet (PoE)?
No, the LBH3080A does not support Power over Ethernet. It is a standard Fast Ethernet switch that requires separate power connectivity. The switch supports redundant 12-48 VDC power input for power resilience in industrial applications.
What type of network management features does this switch offer?
The LBH3080A is an unmanaged switch, meaning it operates as a plug-and-play device without configuration interfaces or management protocols. It includes basic features like auto-negotiation, auto MDI/MDI-X, and broadcast storm protection, but does not support VLANs, QoS, or SNMP management.
What power input options are available for this industrial switch?
The switch supports redundant 12-48 VDC power input, allowing connection to standard industrial power supplies. It includes a P-Fail relay that monitors power status and can trigger alarms or notifications if power fails, providing additional reliability for mission-critical applications.
