Ubuntu uses a service, Network UPS Tools (NUT), to monitor UPSes and take given actions when they send signals.

The Eaton 5e is not a network UPS, its USB. This is what I needed to do to set it up.

$ sudo apt install nut nut-client

For whatever reason, I didn't have USB libraries on my install of 24.04. So:

$ sudo apt install libusb-1.0-0-dev

• Format a USB drive as either FAT16 or FAT32

• Copy the files in these two zips onto it (unzip them first):

  • https://docs.broadcom.com/docs-and-downloads/host-bus-adapters/host-bus-adapters-common-files/sas_sata_6g_p20/9210-8i_Package_P20_IR_IT_FW_BIOS_for_MSDOS_Windows.zip
  • https://docs.broadcom.com/docs-and-downloads/host-bus-adapters/host-bus-adapters-common-files/sas_sata_6g_p20/Installer_P20_for_UEFI.zip

• Leave the USB plugged in (this is important), then reset your machine

• During boot, keep smashing F11 to get a boot selector menu. Once you have it, choose the Built in EFI shell as your boot enivironment

• Once that boots up, it will list the block devices (hard drives) attached to your machine, but it should also pick up a filesystem on your USB drive. It can only do this on boot, which is why its important to make sure the USB is plugged in at boot time.

Create a role with a trust policy that can be assumed by Cloudformation. Trust policy looks like this:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "",
 "Effect": "Allow",

• Download the CLI version of etcher from here: https://github.com/balena-io/balena-cli/blob/master/INSTALL.md
  • (on macs you can just do brew install balena-cli )
• Once you have it downloaded, executable, and on your path, do this:

# connect your flash drive
# make sure it is visible to etcher

$ balena util available-drives
