[Mathew Howard]

It disables the short circuit protection. if you actually do short out a
port with long cable mode on, it will kill the power output on the port
permanently... if you do it without that on, it will typically just shut it
down and it'll work again after resetting it.

You can usually get around the problem by feeding them a bit higher
voltage. I usually run everything at 27v instead of 24v.

regular powerbox have that setting and powerbox pro do not have that settings 
anymore its automatically turned on.

There must be a purpose to this setting, but I don't grasp what it would 
be.

Is there any reason not to always have "poe-in-long-cable=yes"?

The Baicells CPE is not 48v, however. Stuck with 24v with this setup.

Re: [AFMUG] Mikrotik Powerbox Short Circuit Message

[Tim Reichhart]

Actually I had this problem with powerbox pro if you trying to power anything 
over 100ft you can get low voltage and get this message because when I try to 
power up 3 prisms I get short circuit message because the voltage is at 21v it 
needs to be at lease 24v or 48v to make it correctly work. You probably need to 
use the 48v power supply from miktroik.

That is a royal pain if I went through all of that for a setting. The
strange thing is that the output port is the short cable at about 3', the
input is about 80'.

Re: [AFMUG] Mikrotik Powerbox Short Circuit Message

The powerbox is showing over 23v, so I don't think it is a voltage drop
issue.

Re: [AFMUG] Mikrotik Powerbox Short Circuit Message

[Adam Moffett]

Hmm...Is the Baicells thing 24v or 48v?  I think at 48v it took an 
excessive amount of cable or excessive current to have a problem.

Have you worked out the current needed and the voltage drop created by 
the cable?  It might be that the voltage drop is so much that you are
