Im trying to understand what these errors are that I get on PRTG. Ill post the commands I used to see what the switch tells me about the transceiver. Any insight is always appreciated.
mA: milliamperes, dBm: decibels (milliwatts), NA or N/A: not applicable. ++ : high alarm, + : high warning, - : low warning, -- : low alarm. A2D readouts (if they differ), are reported in parentheses. The threshold values are calibrated.
