- 2x 2dBi 2.4G MIMO antenna
- 2x 3dBi 5.8G MIMO antenna
- 5x 1 Gbps Ethernet (QCA8075)
- POE: 48V (IEEE 802.3af)
- power: 12V (~1.5A)
- 1x passthru port (rj45 - rj45)

- size: 160mm*86mm*29mm

BACKUP YOUR STOCK FIRMWARE:
```
export device=fap650
mkdir -p /tmp/fw_dump_$device
cd /tmp/fw_dump_$device
dmesg > dmesg_$device.log
dtc -I fs /sys/firmware/devicetree/base > $device.dts
cat /proc/device-tree/model > model
cat /proc/mtd > proc_mtd
while read p; do
mtd_dev=$(echo $p | cut -d: -f1)
echo $mtd_dev
dd if=/dev/$mtd_dev of=$mtd_dev
done < proc_mtd
md5sum * > md5sum.log
tar -cvzf ../$device.tar.gz .
export sum=$(md5sum /tmp/$device.tar.gz | cut -d' ' -f1)
mv ../$device.tar.gz /tmp/${device}_${sum}.tar.gz
echo fw backup saved to: /tmp/${device}_${sum}.tar.gz
```
Upload your backup via tftp to the safe place.

INSTALLATION:
1. stock firmware web ui
Rename factory.bin fw image file to factory.ubin. Flash this image
like ordinary stock fw upgrade.

2. stock firmware telnet method
Enter telnet cli (login: root, password: 476t*_f0%g09y) and upload
 factory.bin fw image and rename it to factory.ubin
`cd /tmp && wget <your_web_server_ip>/factory.ubin`
`sysupgrade factory.ubin

3. initramfs method
    Put imitramfs image to your TFTP server and rename it for example to fap650.initram
    Enable serial console and enter to the u-boot cli.
    Exec these commands:
    `tftpboot <your_tftp_server_ip>:fap650.initram`
    `dhcp`

    When downloading is finished:
    `bootm`
    After booting the device, you need to upload to the device factory.ubi fw image.
    ```
    cd /tmp && wget <your_web_server_ip>/factory.ubi`
    export rootfs=$(cat /proc/mtd | grep rootfs | cut -d: -f1)
    export rootfs_1=$(cat /proc/mtd | grep rootfs_1 | cut -d: -f1)
    ubiformat /dev/${rootfs} -y -f factory.ubi
    ubiformat /dev/${rootfs_1} -y -f factory.ubi
    reboot
    ```

4. u-boot factory.ubi image method
    Put factory.ubi to your TFTP server
    Enter u-boot cli and exec these commands:
    `tftpboot <your_tftp_server_ip>:factory.ubi`
    `dhcp`
    After downloading is finished:
    `flash rootfs`
    `flash rootfs_1`
    `reset`

STOCK FIRMWARE RECOVERY:
Boot initramfs image.
Upload your rootfs mtd partition to the device using scp or download
it from the device using wget.
Enter device ssh cli and exec:
```
cd /tmp && wget <your_web_server_ip>/rootfs_mtd`
export rootfs=$(cat /proc/mtd | grep rootfs | cut -d: -f1)
export rootfs_1=$(cat /proc/mtd | grep rootfs_1 | cut -d: -f1)
ubiformat /dev/${rootfs} -y -f /tmp/rootfs_mtd
ubiformat /dev/${rootfs_1} -y -f /tmp/rootfs_mtd
reboot
```
