Industrial edge switch

The Black Box Innovations LPH3100A is an eight-port unmanaged Gigabit Ethernet switch built for extreme environments. It operates reliably from -40°C to +75°C inside a sealed IP30 metal enclosure that resists dust, dirt and moisture. The unit can be DIN-rail or wall mounted for flexible deployment in industrial facilities, loading docks and remote monitoring stations.

Suited for harsh-edge deployments.

This switch targets installers who need PoE+ power delivery and rugged construction where temperatures swing wildly and contaminants are present. It is not intended for buyers who require managed features such as VLANs, QoS or remote monitoring, nor for those who need fibre uplinks or additional ports beyond the eight copper interfaces provided.

PoE+ power budget across eight copper ports

Each of the eight autosensing 10/100/1000-Mbps ports delivers up to 30 W to connected devices, allowing security cameras, wireless access points and automation equipment to operate without local power outlets. The two extra Gigabit copper ports provide uplink connectivity for backhauling data to the core network.

Questions about this item

How is the LPH3100A mounted and what step is often missed?

The switch can be DIN-rail or wall mounted using its IP30 metal case; the step often missed is ensuring the mounting surface is grounded to maintain the rugged seal against dust and moisture.

What maintenance or replacement will the LPH3100A need over time?

The fanless, sealed IP30 enclosure has no user-serviceable parts; maintenance is limited to periodic visual checks for dust buildup on the case vents and verifying PoE port LEDs remain green under load.

What is the first limit the LPH3100A hits under sustained PoE+ load in a hot cabinet?

The operating ceiling of +75 °C (+167 °F) is the first hard limit; sustained PoE+ output across all eight ports raises internal temperature, so airflow around the metal case must stay clear to avoid thermal shutdown.
