I have a DEQNA cabinet kit that does not work. I know this because if I
replace it with another one the activity light on the switch works and I am
able to see MOP requests coming from the machine to my boot node, with the
faulty one none of this happens.
I asusme the 2 cabkits are of the same type,. there's not some differnece
between them
Now, I have tested the fuse and I have tested the connectivity of every wire
from the internal connector that connects to the DEQNA board (also tried
with a DELQA by the way) to the AUI connector on the outside of the cabinet
kit. Everything seems to be OK. But it doesn't work. I have tried
"jiggling"
the wires a bit while testing the continuity of the wires, but it still
seems OK.
IIRC there is a ltitle electronics in these cabkits, something like a
linear voltae regualtor to provide the power for the transceiver. Is it
possible that this has failed. Have yuo measured the votlage ebtween the
transceiver power ins on the AUI connector using both the good and bad
cabkits (with the machine powered up, of course)?
