I had seen that you had responded to tim's post about a pulled plug
it can be just that simple sometimes
we had a digital cross connect system in the early 90s
two bays of gear separated by an aisle for equipment access
no redundancy...our engineers had not wrapped their heads around the concept of catastrophic failure...yet
remember those shiny nylon band jackets?
while taking a group of sightseers on a tour of our latest marvel a tech walked between the bays and pointed out (literally) some unique feature of the backplane
as his nylon-clad torso made contact with one bay and his naked finger touched the opposite bay...the onlookers said they actually heard a zzzzzzt just before the alarms sounded
it took a very long time to fix...ultimately they gave up and did an emergency replacement
in those early days all the programming had to be done manually
over the years it was discovered that contact wasn't required for one of these things to fail
merely walking between the bays or proximate use of the early cellphones would kill it
so pulling a cord causing a catastrophic failure....who knows, but I've seen stranger things than a voltage spike cause trouble
