Imagine if you will, the following scenario.
RB433AH connected to an APC UPS,
Ether 1 - Ether 6 on the RB433AH are all connected to RB411Rs that are in integrated enclosures - making up a rather large access point.
All 7 routerboards are powered via the UPS.
What I'd like is for the RB433AH to get a signal from the UPS if there are power problems and to then let the other RBs know about it and when the time comes, they all shut down if the UPS reaches the end of it's run.
How can I do this?
Thanks in advance
