Hi All,

I am looking for an explanation to why some of our RB's power off and require the DC power plug to be removed either from the RB or passive POE injector to repower them.

There is nothing common amongst the RB's apart from all being wireless hotspots - 433A, H, and 411A. Some are indoor, some use passive poe injectors 10-50 metres, some connect direct into DC socket. Some of the PSU's are different manufacturer but all are 24v 1.25a. We have around 100 units and we often just need to pull the DC power socket on the board and replace to rectify the problem.

Is there some kind of surge protection on the RB's that shuts them off in the event of a surge?

TIA

Darryl

Hi,that mean your electricity network possible is not stable. Old rev. RB4xx is sensitive to ~half second power outage. In all new rev. RB this bug is fixed. Use some UPS or lead acid battery to stabilize power.
