FreeNAS Install And Configure APC UPS For Power Management

To install and configure APC UPS (Uninterruptible Power Supply) for power management on FreeNAS, follow these steps:

1. Install the apcupsd package:
   pkg install apcupsd
2. Enable the apcupsd service to start at boot time:
   sysrc apcupsd_enable=yes
3. Create a configuration file for apcupsd:
   touch /usr/local/etc/apcupsd/apcupsd.conf
4. Open the configuration file in a text editor:
   nano /usr/local/etc/apcupsd/apcupsd.conf
5. Add the following lines to the configuration file, replacing /dev/cuaU0 with the correct device name for your UPS and your-ups-name with a unique name for your UPS:

UPSNAME your-ups-name
UPSCABLE smart
UPSTYPE apcsmart
DEVICE /dev/cuaU0

6. Save and close the configuration file.
7. Start the apcupsd service:
   service apcupsd start

You can verify that the service is running by checking the status:
service apcupsd status

You can also check the current status of the UPS by running the following command:
apcaccess

To configure power management actions, such as shutting down the system in the event of a power failure, you can edit the /usr/local/etc/apcupsd/apccontrol file. The file contains instructions and examples on how to configure the actions.

FreeNAS is a free and open-source operating system based on FreeBSD that is designed for use on network-attached storage (NAS) devices. APC UPS is a brand of uninterruptible power supply that provides backup power in the event of a power outage. By installing and configuring apcupsd, you can use an APC UPS to protect your FreeNAS system from power disruptions and ensure a smooth shutdown in the event of a power failure.
