|Warning! There are 2 version of nanostation xm and xw.|
|Version/Model||Launch Date||OpenWrt Version Supported||Chip||Bugs in Hardware|
|xw||2014||14.07 - for Nanostation M5||ar9342|
|trunk - for Nanostation Loco M5||Most of these devices have a hardware bug in the ethernet chip. This leads to connection loss of eth0 interface. Only a reboot can fix this. See also Bug description. As of August 2015 there is no workaround in OpenWRT available.|
From the beginning of 2014 Ubiquiti has released new model of Nanostaion 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 Nanostation Loco M5 there is a new image (openwrt-ar71xx-generic-ubnt-loco-m-xw-squashfs-factory.bin) - for models since 2014 - available in trunk, but not included in Barrier Breaker.
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
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/
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.

In CLI this will work to change the poe pass trough instantly without rebooting or waiting for config to apply. Email from development mailing list.
to switch the poe pass trough on use this:
# 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

A pin header can be soldered to the board to use the serial port. The board is mounted to a sled which can be pulled out after the protective cover for the RJ-45 port is removed.
