Recently upgraded an old Cisco router to Mikrotik 1100AHx2 and due to other upgrades realised I had no way to monitor the UPS anymore. Was hoping to use the MT to watch the UPS and when on battery send a sign (email/http post etc) to some script / software I will write to shut the hosts down. Anyway MT does connect to the UPS (its over serial by the way, and MT is running 5.26) but I get a red exclamation mark to the left of it on the system>ups screen (this is in winbox) but other than that all seems well, can see voltages and UPS info.
The problem is this, if power fails, UPS takes the load, but MT shuts down immediately. If I play with the runtime / offline time timers setting them to anything except 5 mins results in MT shutting down immediately on power fail. If I set to 5 mins the MT counts down, and I guess would shut down at zero, and I get nice log entries to say on battery, and then on mains again when UPS is back live.
What I want it to do, is to leave the UPS (and MT running) until battery low. There is approx 33mins of runtime, but the MT will never get there!
If I set the runtime / offline to zero (as suggested in help) the MT should sit and wait, but it doesn’t, it immediately shuts down.
Anyone else seeing this issue? Maybe a bug in 5.26?
any help appreciated!
