Fortinet FAP-220-B is a dual-radio, dual-band 802.11n enterprise managed access point with PoE input and single gigabit Ethernet interface. Hardware highlights: Power: 802.3af PoE input on Ethernet port, +12V input on 5.5/2.1mm DC jack. SoC: Atheros AR7161 (MIPS 24kc at 680MHz) RAM: 64MB DDR400 Flash: 16MB SPI-NOR Wi-Fi 1: Atheros AR9220 2T2R 802.11abgn (dual-band) Wi-Fi 2: Atheros AR9223 2T2R 802.11bgn (single-band) Ethernet: Atheros AR8021 single gigabit Phy (RGMII) Console: External RS232 port using Cisco 8P8C connector (9600-8-N-1) USB: Single USB 2.0 host port LEDs: Power (single colour, green), Wi-Fi 1, Wi-Fi 2, Ethernet, Mode, Status (dual-colour, green and yellow) Buttons: reset button hidden in bottom grill, in the top row, 2nd column from the right. Label MAC address: eth0 FCC ID: TVE-220102 Serial port pinout: 3 - TxD 4 - GND 6 - RxD Installation: The same methods apply as for already supported FAP-221-B. For both methods, a backup of flash partitions is recommended, as stock firmware is not freely available on the internet. (a) Using factory image: 1. Connect console cable to the console port 2. Connect Ethernet interface to your PC 3. Start preferred terminal at 9600-8-N-1 4. Have a TFTP server running on the PC. 5. Put the "factory" image in TFTP root 6. Power on the device 7. Break boot sequence by pressing "Ctrl+C" 8. Press "G". The console will ask you for device IP, server IP, and filename. Enter them appropriately. The defaults are: Server IP: 192.168.1.1 # Update accordingly Device IP: 192.168.1.2 # Update accordingly Image file: image.out # Use for example: openwrt-ath79-generic-fortinet_fap-220-b-squashfs-factory.bin 9. The device will load the firmware over TFTP, and verify it. When verification passes, press "D" to continue installation. The device will reboot on completion. (b) Using initramfs + sysupgrade 1. Connect console cable to the console port 2. Connect Ethernet interface to your PC 3. Start preferred terminal at 9600-8-N-1 4. Have a TFTP server running on the PC. 5. Put the "initramfs" image in TFTP root 6. Power on the device. 7. Break boot sequence by pressing "Ctrl+C" 8. Enter hidden U-boot shell by pressing "K". The password is literal "1". 9. Load the initramfs over TFTP: > setenv serverip 192.168.1.1 # Your PC IP > setenv ipaddr 192.168.1.22 # Device IP, both have to share a subnet. > tftpboot 81000000 openwrt-ath79-generic-fortinet_fap-220-b-initramfs-kernel.bin > bootm 81000000 10. (Optional) Copy over contents of at least "fwconcat0", "loader", and "fwconcat1" partitions, to allow restoring factory firmware in future: # cat /dev/mtd1 > /tmp/mtd1_fwconcat0.bin # cat /dev/mtd2 > /tmp/mtd2_loader.bin # cat /dev/mtd3 > /tmp/mtd3_fwconcat1.bin and then SCP them over to safety at your PC. 11. When the device boots, copy over the sysupgrade image, and execute normal upgrade: # sysupgrade openwrt-ath79-generic-fortinet_fap-220-b-squashfs-sysupgrade.bin Return to stock firmware: 1. Boot initramfs image as per initial installation up to point 9 2. Copy over the previously backed up contents over network 3. Write the backed up contents back: # mtd write /tmp/mtd1_fwconcat0.bin fwconcat0 # mtd write /tmp/mtd2_loader.bin loader # mtd write /tmp/mtd3_fwconcat1.bin fwconcat1 4. Erase the reserved partition: # mtd erase reserved 5. Reboot the device Quirks and known issues: - The power LED blinking pattern is disrupted during boot, probably due to very slow serial console, which prints a lot during boot compared to stock FW. - "mac-address-ascii" device tree binding cannot yet be used for address stored in U-boot partition, because it expects the colons as delimiters, which this address lacks. Addresses found in ART partition are used instead. - Due to using kmod-owl-loader, the device will lack wireless interfaces while in initramfs, unless you compile it in. - The device heats up A LOT on the bottom, even when idle. It even contains a warning sticker there. - Stock firmware uses a fully read-write filesystem for its rootfs. - Stock firmware loads a lot of USB-serial converter drivers for use with built-in host, probably meant for hosting modem devices. - U-boot build of the device is stripped of all branding, despite that evidence of it (obviously) being U-boot can be found in the binary. - The user can break into hidden U-boot shell using key "K" after breaking boot sequence. The password is "1" (without quotes). - Telnet is available by default, with login "admin", without password. The same is true for serial console, both drop straight to the Busybox shell. - The web interface drops to the login page again, after successfull login. - Whole image authentication boils down to comparing a device ID against one stored in U-boot. - And this device is apparently made by a security company. Big thanks for Michael Pratt for providing support for FAP-221-B, which shares the entirety of image configuration with this device, this saved me a ton of work.
