We found the comment related to removal of voltage limiting components that was lodged during the SA ballot on Annex J by Mick Maytum (a surge protection expert, unfortunately no longer with us). See
https://www.ieee802.org/3/cr/Comments/D3.0_Unsatisfied.pdf for the full text of the comment and response. The suggested remedy actually asked us to require removal of the components – the comment resolution group disagreed: Add the following text "Voltage limiters intended to prevent Ethernet port insulation breakdown shall be removed for AC and DC voltage testing if their limiting voltage is less than the specified AC or DC test voltages applied. For impulse testing, voltage limiters may be left in place to perform their intended function. If removed for impulse testing, the voltage limiter shall pass the impulse test when separately tested." REJECT. The CRG disagrees with the commenter. There was no consensus to change the text based on the commenters suggested remedy. George Zimmerman, Ph.D. President & Principal CME Consulting, Inc.
