Ubiquiti Nanostation M5 / Loco M5

Warning! There are two versions of NanoStation: xm and xw.

The old xm version has limited RAM (32 MB) and thus is not recommended.

xm - 14.07 ar724x
xw 2014 14.07 - for Nanostation M5 ar9342
14.07 - for Nanostation Loco M5 A hardware bug causing loss of eth0 connectivity was fixed in OpenWrt 17.01.

In 2014 Ubiquiti released a new model of Nanostation M5 devices (old boards use ar724x chip while new ones are using ar934x chip).

New Ubiquiti Nanostation M5 firmware page devices use xw firmware image, while older use xm image.

  • For newer Nanostation Loco M5 (XW) (models since 2014) there is a new image (openwrt-ar71xx-generic-ubnt-loco-m-xw-squashfs-factory.bin).
  • For old Nanostation Loco M5 (XM) the image name is openwrt-ar71xx-generic-ubnt-nano-m-squashfs-factory.bin.

If you have installed OpenWrt and issue cat /proc/cpuinfo or look trough boot messages XW based hardware should come back as Atheros AR93xx, XM = Atheros AR72xx

Installation

Install OpenWrt (generic explanation)

Image name: openwrt-ar71xx-generic-ubnt-nano-m-…

You can install the *-factory image over the webinterface or via tftp rescue. Webinterface default address is http://192.168.1.20/

You may need to downgrade the original AirOS firmware to v5.5 in order to allow a firmware upload via the web interface. Upload via TFTP should work even for new AirOS versions.

To enter tftp rescue mode power cycle the device while keep the reset button pushed (for ~10 sec). Leds will start to blink red and yellow.

# pick an address in the range 192.168.1.1-254 for your network device
# tftp 192.168.1.20
tftp> bin
tftp> trace
# depending on your version **xm** or **xw**
tftp> put openwrt-ar71xx-generic-ubnt-nano-m-squashfs-factory.bin
tftp> put openwrt-ar71xx-generic-ubnt-nano-m-xw-squashfs-factory.bin

Installing OpenWrt via TFTP

PoE passtrough

It is possible to supply power to another device via the secondary ethernet port. POE passthrough is disabled by default.

Device Model GPIO pin
xm 8
xw 2

Configure via UCI

The POE passthrough GPIO pin is configurable via UCI:

uci show system.poe_passthrough

Permanent configuration changes can be specified via command line:

uci set system.poe_passthrough.value=1
uci commit system

Temporary changes via CLI

Run the following commands to change the state of the POE passthrough switch:

# nanostation xm
echo 8 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio8/direction
echo 1 > /sys/class/gpio/gpio8/value
# disable with echo 0 > /sys/class/gpio/gpio8/value
# nanostation xw
echo 2 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio2/direction
echo 1 > /sys/class/gpio/gpio2/value
# disable with echo 0 > /sys/class/gpio/gpio2/value

This state does not survive a reboot. See the UCI based setting above for permanent configuration changes.
