Did you flip the voltage switch on the back to the 230V setting? If it were
on 115V and you were powering off 230V, the normally warm echoplex would
become positively molten...

If it's as hot as you say, its more likely that the regulators are going
into thermal overload and shutting off.

that's what happens when it is way outside of it's normal temperature
range. I only ever made it do that sort of thing by blowing a heat gun on
it until it failed. (ie, making it extremely hot.)

It should run the same with 115V or 230V, assuming the switch is set right.

are there other things in the rack generating heat? Or is air flow in the
rack limited?
