Re: [AFMUG] Mikrotik Powerbox Short Circuit Message
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. -Original Message- From: "Adam Moffett" To: af@afmug.com Date: 11/03/17 10:24 Subject: Re: [AFMUG] Mikrotik Powerbox Short Circuit Message There must be a purpose to this setting, but I don't grasp what it would be.

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

Re: [AFMUG] Mikrotik Powerbox Short Circuit Message
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. -Original Message- From: "Matt Hoppes" To: af@afmug.com Date: 11/02/17 08:36 Subject: Re: [AFMUG] Mikrotik Powerbox Short Circuit Message It's the input cable that's the issue.

Yep, what Matt said... that setting will more than likely fix it.

Re: [AFMUG] Mikrotik Powerbox Short Circuit Message
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
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. -- Original Message -- From: "Chuck McCown" To: af@afmug.com Sent: 11/2/2017 7:22:20 PM Subject: Re: [AFMUG] Mikrotik Powerbox Short Circuit Message Have you worked out the current needed and the voltage drop created by the cable?
