Keep all the at-risk outside runs ON the 170 (8ex)! Much cheaper/easier to get/change a module than the card IN the 816.
Check if you have 16v on the second pair (wh/or), the protection circuit might see a short and have the dpits power shut down. You should have 33v on the first pair (wh/be). If you are using apits sets, be sure xdp is disabled. I'm assuming you are using slts as the external sets, and don't have the second pair extended thru the long cable. If the 16v is shut down, check for a shorted pulse transformer (black coated transformer) on the ports that got hit, they will short between winding easily on lightning hits. With power disconnected, check for less than 10 ohms between second pair on each port. You can steal transformers from a cheap kxt1232 dss card ;-) Card will work with removed bad transformer (obviously not the bad port). -- larry / dallas Russ Hay wrote: > Hi all - thanks for the advice so far - this module has been installed > in the top expansion slot of the KXTD816.
