Power over Ethernet has quietly become critical infrastructure - it's powering your access points, IP phones, security cameras, and an ever-expanding fleet of IoT devices. But as PoE standards have evolved through 802.3at and into 802.3bt (up to 90 watts per port), the question isn't just does it power up - it's does it comply? Discovering a non-compliant device after it's deployed across dozens of sites is a very different problem than catching it in the lab.
ANDOVER, MA / ACCESS Newswire / May 5, 2026 / In this episode of The Tolly Group Analyst Preview, Kevin Tolly provided his analyst insights into the Sifos MPD-600 - a rack-mountable, six-port PoE test instrument built to put powered devices through their paces before they ever touch a production network.
What Kevin Tolly Covers in This Episode
What the MPD-600 actually does - and why IT teams, systems integrators, and manufacturers all have a stake in PoE compliance testing
Simultaneous six-port testing across all PoE power classes - from legacy Class 0 through Class 8 at up to 71 watts
Voltage flexibility testing at 43V, 49V, and 55VDC - simulating everything from long cable runs to short connections, to ensure devices behave across real-world deployments
Automatic violation detection - inrush current monitoring, maintain power signature verification, and class-specific power policing that captures exactly when and how a device fails spec
Three testing modes (Plug 'n Test, Group Interop Test, Diagnostic PD Test) - and when to reach for each one, from quick field verification to extended intermittent-fault capture
Network integration for managing devices under test - how the MPD-600's dedicated GbE ports let technicians interact with powered devices over the network while testing runs
Automation and API support - PowerShell MPD, Tcl/Tk, and C/C++/Python APIs for teams that need to embed PoE qualification into a production line
