Hard to answer. Power up the MT with it resting on something that is not conductive.
Measure from both sides of the incoming power to the chassis and ethernet shield connection. If there is no voltage between chassis and shield and either side of the power input it is probably a floating load. If it is a floating load you can hook it up to any source of 48 volts. However, if you measure a voltage from chassis to the positive input, then it is a negative ground load and will short out a –48 input.

Should I expect a cat 5 connection between the router and the DSLAM to cause issues? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP
