PoE device doesn't function properly
• Ensure that all devices are turned on
• Ensure that the PoE device is functioning by plugging it directly
into the PoE switch, computer, etc.
• Double-check that the cables were connected properly
• Run a continuity test on all wires in the cable
• Equipment at both ends must be at the same link speed,
10BaseT with 10BaseT, 100BaseT with 100BaseT, etc.
• Replace with a higher-grade cable for better performance
• Ensure that the cable lengths are within the allowable range and
consistent with the remote PoE device power consumption, and
reduce cable length as needed
• Check that power consumption is within the specifications
