Step 1 : Configuring RouterOS APC UPS Protection

To sccessfully configure you RouterOS follow the steps as listed below :

1) Connect to your RouterBoard using your RJ45 network cables on ETHER2 and the ethernet port on your laptop / desktop
2)Connect a USB or RS232 cable from your RouterBoard to your APC UPS in this tutorial a USB cable was used.
3) Next go to SYSTEM > PACKAGES to check if the UPS package is installed. If you do not see it as show in the image on the left you have to download the EXTRAS package for your RouterBoard from www.mikrotik.com.

3) Extract the downloaded extra packages archieve file, In Winbox go to FILES and click UPLOAD. Select the file named UPS-6.45.6-MIPSBE and after the file upload completes go to SYSTEM > REBOOT to install the UPS package.

4) After successfull installation of the UPS package you should see it if you go to SYSTEM > UPS. You can check if the UPS package installation is okay by going to SYSTEM > PACKAGES and select the UPS PACKAGE and click on the CHECK INSTALLATION BUTTON(YOU SHOULD GET A INSTALLATION OK MESSAGE). Also ensure that your RouterOS version is on the latest stable version to ensure installation success.

 

5) Next go to SYSTEM > UPS and click the add button. In the dialog that appears add a name for your UPS i.e “APCBACKUPS950” select the port where the UPS is connected to on the port dropdown and set the OFF LINE TIME and MIN RUN TIME values depending on UPS runtime capability. Finally set the ALARM SETTING TO IMMEDIATE( However you can choose any other alarm setting you would want for your UPS). You can also check the MODEL and STATUS tabs to get UPS information such as LOAD and RUNTIME LEFT metrics.

6) The OFFLINE TIME value is the duration that the RouterBooaurd will run whilst on battery. The RouterBoard waits for the amount of time configured and if this time lapse it goes into hibernation mode until the UPS reports that normal power has been restored.
The MIN RUN TIME value is used by RouterOS such that when a power failure occurs RouterOS will monitor the runtime-left value and will go to hibernate mode when this time value is reached.

Step 2 : Configuring Power Monitoring

7) Here we are going to configure UPS power minitoring so that when a power fault occurs you will get an email notification informing you that UPS power is online or offline/ on battery. To do this follow these steps :
