I had one at home do the exact same thing this weekend. I was able to do the firmware recovery (I think), as it accepted a tftp upload after holding the reset for 8 seconds after power-on. The two ports I had PoE enabled on did turn on once a couple of reboots after the recovery, but then

WILL NOT ACCEPT -48VDC (positive on Earth/chassis/tower ground) AT ALL! If an “X” radio has been powered by -48VDC with respect to case (tower ground) it will surely be damaged!* * * Regards, Alex On Jun 28, 2017, at 6:30 PM, Kristian Hoffmann <kh...@fire2wire.com <mailto:kh...@fire2wire.com>>

[Ubnt_users] AF24 and -48VDC input?

2017-06-27 Thread Kristian Hoffmann
Hi, Is the AF24's internal power supply isolated in such a way that it can be powered with -48VDC, like other telco equipment with a positive ground, or will this cause a short when mixed with other -48VDC equipment on the same ground plane? Thanks, -- Kristian Hoffmann Fire2Wire kh

[Ubnt_users] AF5x packet loss

2018-02-21 Thread Kristian Hoffmann
Hi, This is going to sound crazy, but here we go... Has anyone seen packet loss across an AF5x link that occurred exactly every 30 seconds?  I have a couple of links, on completely different towers, that drop packets every 30 seconds.  I can observe it using the MikroTik traffic generator, or
