These instructions should work for just about any APC Network Management card (NMC), but the one I’m using is the AP9631.
Step #1: Navigate to the UPS configuration options
There are two ways to get into the UPS configuration:
- Navigate to Services -> UPS in the sidebar, or …
- Click on Services at the top of the page, then click the wrench icon next to UPS
It makes no difference which one you choose.
Step #2: Configure the UPS
As stated earlier, I’m using an AP9631 so I’ll select the driver closest to that model. In this case, it is the APC ups 3 (various) AP9630 monitoring card (snmp-ups privProtocol=AES) driver:
… And then continue with the configuration.
- Identifier is how FreeNAS will refer to your UPS.
- Port is the IP address of the network management card
- Shutdown mode can be one of the following (you’ll have to decide which one of these is appropriate for your environment):
- UPS reaches low battery
- UPS goes on battery
- Monitor User is the username of the user that exists on the NMC that will be used to issue shutdown commands. The AP9631 ships with a user called “device”, but you need to change the password for this user when you configure your NMC.
- Monitor Password is the corresponding password for the NMC user.
- Remote Monitor this option allows other servers to monitor the UPS via the NAS. You may or may not need this functionality.
- Send Email Status Updates and To email these should be self explanatory.
Once you’ve saved your configuration, start the service:
Step #3: Verify the UPS service is communicating with the NMC
Open a terminal and ssh to your NAS and run the following command (where APCNMC is the Identifier you entered in your UPS configuration):
You should see something like this:
