Summary
The UPS monitor feature works with APC UPS units that support “smart” signaling over serial
RS232 or USB connection. This feature enables the network administrator to monitor the UPS and
set the router to ‘gracefully’ handle any power outage with no corruption or damage to the router.
The basic purpose of this feature is to ensure that the router will come back online after an extended
power failure. To do this, the router will monitor the UPS and set itself to hibernate mode when the
utility power is down and the UPS battery is has less than 10% of its battery power left. The router
will then continue to monitor the UPS (while in hibernate mode) and then restart itself after when
the utility power returns. If the UPS battery is drained and the router loses all power, the router will
power back to full operation when the ‘utility’ power returns.
The UPS monitor feature on the MikroTik RouterOS supports
• hibernate and safe reboot on power and battery failure
• UPS battery test and run time calibration test
• monitoring of all "smart" mode status information supported by UPS
• logging of power changes
