Cause

Both MTN880451 as well as MTN880541 has a power consumption about 285 mW, that gives about 7 mA. The power supply MTN884019 could give 1.3 A used with 230 Volt or 1 A used by 115 Volt, so it is more than the number of devices you could have on a segment that are important.
 

Resolution

Both MTN880451 as well as MTN880541 has a power consumption about 285 mW, that gives about 7 mA. The power supply MTN884019 could give 1.3 A used with 230 Volt or 1 A used by 115 Volt, so it is more than the number of devices you could have on a segment that are important.

If you use LinkPower, you theoretical have up to 128 devices, but if you also have FTT devices, these should be counted twice, so 20 LPT and 15 FTT devices should be counted as 50.

It is a recommendation to stay below 64 devices on one segment.
