Frequently Asked Questions
What is an industrial Ethernet PoE+ switch used for?
An industrial Ethernet PoE+ switch combines network connectivity and power delivery in a single device, ideal for powering and connecting industrial cameras, wireless access points, IoT sensors, and automation controllers in harsh environments where traditional infrastructure is impractical.
Can the LPH3100A operate in extreme temperatures?
Yes. The Black Box LPH3100A is specifically designed for extreme-temperature industrial environments. Its IP30 metal enclosure and industrial-grade components ensure reliable operation in demanding conditions where standard commercial switches would fail.
What does redundant power input mean?
Redundant 12–24 VDC power inputs provide automatic failover protection. If one power source fails, the switch seamlessly switches to the backup supply, ensuring continuous network availability. The P-fail relay alerts your system to power loss events.
Is the LPH3100A managed or unmanaged?
The LPH3100A is an unmanaged switch, meaning it requires zero configuration. Simply connect power and network cables — it operates immediately without software setup or management overhead, making it ideal for rapid deployment in remote or harsh industrial sites.
