Controller wired wrong

[lonewolf41]

What would happen if someone (hypothetically) switched the positive and negative bundle of wires connected to the SSC from the CAT5?  So instead of :

3 (Positive)
    White with Blue Stripe
    Blue
    White with Green Stripe

4 (Ground)
    Green
    White with Brown Stripe
    Brown

It was (hypothetically) hooked up as:

3 (Positive)
    Green
    White with Brown Stripe
    Brown
   
4 (Ground)
    White with Blue Stripe
    Blue
    White with Green Stripe

What components would be toast and need to be (hypothetically) replaced?

Thanks,

     You could damage the first node.....

Hypothetically,

I'd start with the fuse...

I'd test any nodes with a known good ssc on a known good port on the hub

After correcting the wiring, I would check the input terminal for12v and then check the output of the 5v and 3.3v regulators wit no strings attached.

If everything so far passes, hook up a single node or a short string.

What could be dead - fuse, 5v reg, 3.3v reg, 485 chip, PIC, string...
No electrolytic caps, so all the capacitors should all be fine. Resistors don't care which way the current flows.
