Single-cable design simplifies underground electrical deployment while improving reliability and content delivery
Sudbury, Ontario — Extending electrical power underground is one of the most complex, costly, and safety-critical aspects of deploying digital infrastructure in mining environments. Maestro Digital Mine is addressing that challenge with the launch of its Power over Ethernet (PoE)-enabled SuperBrite™ Marquee Display. By delivering power and real-time data over a single Ethernet cable through Maestro’s Plexus PowerNet communications system, the display eliminates the need to run high-voltage AC power to each unit, simplifying installation and reducing electrical risk underground.
In underground operations, installing traditional AC-powered digital signage often requires certified electricians, additional panels and breakers, safety inspections, and production interruptions that increase project scope, cost, and scheduling complexity. PoE significantly lowers that barrier by allowing displays to be powered using low-voltage Ethernet cabling, reducing installation time and safety constraints. Reducing separate power infrastructure also minimizes potential failure points in environments where dust, vibration, and moisture are constant challenges.
“Extending electrical power in underground mining environments introduces cost, risk, and operational disruption,” said Michael Gribbons, Founder, President and CEO of Maestro Digital Mine. “By using Power over Ethernet, the SuperBrite™ Marquee Display removes the need to treat signage as a special electrical project. It becomes a standard, managed network device, delivering trusted information reliably without introducing additional electrical complexity underground.”
Designed for continuous 24/7 operation in harsh underground environments, the SuperBrite™ Marquee Display provides high-visibility LED readouts of real-time environmental and ventilation data, including airflow, gas concentrations, humidity, and temperature. As part of the Maestro Digital Mine ecosystem, the display integrates directly with Vigilante AQS™ and Zephyr AQS™ air quality monitoring stations, delivering live data over a managed PoE network rather than relying on locally maintained systems. Centralized power and network management allow operators to monitor device status, reset displays remotely, and ensure information remains current and visible underground.
Built-in fail-safe behavior alerts crews if communication is lost, preventing outdated information from being relied upon. When powered through PoE switches with backup power, displays can also maintain predictable operation during brief outages, supporting more consistent information delivery in safety-critical environments.
By eliminating the requirement for dedicated electrical infrastructure at each display, the PoE-enabled SuperBrite™ Marquee Display also makes it easier to add, replace, or relocate signage as underground networks expand—without triggering additional electrical work or re-certification.
Maestro Digital Mine will be attending SME MineXchange 2026, taking place February 22–25 in Salt Lake City, Utah. The company will be available to discuss the PoE-enabled SuperBrite™ Marquee Display, along with its broader underground communications and monitoring solutions, at Booth #1126.
