Just upgraded a couple of epmp 2000s to 4.5.0 and I receive 403 forbidden when i try to download the S/A tool. Anyone else having this issue? 4.4.3 works.

Hi,

You can dowload it as a separate tool on our support site:

[https://support.cambiumnetworks.com/files/epmp/](https://support.cambiumnetworks.com/files/epmp/)

Java Web Start SA tool was removed from the firmware.

Thanks,

Dmitry

Apparently I missed that giant line in the release notes. Much appreciated.

It is now moved elsewhere! I searched for him for a while. This shouldn't happen much, especially when one stops and wants to scan quickly.

Where are the instructions on how to use it?&nbsp; How to get it to work?  
  
My Support Ticket person tells me the reason the GUI SA is crashing with a 'Spectral Tools' error, is because it's been removed.&nbsp; I think (again) they haven't actually used the gear, and this person doens't know what they are talking about.&nbsp; This is after them telling me that there ''are no reported problems with the SA"  
  
Anyway - I'm a few days into the Support Ticket, and I want to give them the benefit of the doubt.&nbsp; I have downloaded and installed the "CambiumSA" and when I run it, I put in the IP - - and I just get a "connection refused: connect" message.
