To make them output power, install the "poemgr" package from the packages feed. This package can control the PD69104B1 PSE controller. Installation ------------ 1. Connect to the booted device at 192.168.1.20 using username/password "ubnt" via SSH. 2. Add the uboot-envtools configuration file /etc/fw_env.config with the following content $ echo "/dev/mtd1 0x0 0x1000 0x10000 1" > /etc/fw_env.config 3. Update the bootloader environment. $ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr); fdt rm /signature; bootubnt" $ fw_setenv bootcmd "run boot_openwrt" 4. Transfer the OpenWrt sysupgrade image to the device using SCP. 5. Check the mtd partition number for bs / kernel0 / kernel1 $ cat /proc/mtd 6. Set the bootselect flag to boot from kernel0 $ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4 7. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1 $ dd if=openwrt.bin of=/dev/mtdblock6 $ dd if=openwrt.bin of=/dev/mtdblock7 8. Reboot the device. It should boot into OpenWrt. Restore to UniFi ---------------- To restore the vendor firmware, follow the Ubiquiti UniFi TFTP recovery guide for access points. The process is the same for the Flex switch.
