The Ubiquiti NanoBeam AC Gen1 XC (NBE-5AC-19) is an outdoor 802.11ac CPE
with a waterproof casing (ultrasonically welded) and bulb shaped. 

Hardware:
 - SoC: Qualcomm Atheros QCA9558
 - RAM: 128 MB DDR2
 - Flash: 16 MB SPI NOR
 - Ethernet: 1x GbE, AR8033 phy connected via SGMII
 - PSU: 24 Vdc passive PoE
 - WiFi 5 GHz: Qualcomm Atheros QCA988X
 - Buttons: 1x reset
 - LEDs: 1x power, 1x Ethernet, 4x RSSI, all blue
 - Internal antenna: 19 dBi planar

Installation from stock airOS firmware:
 - Follow instructions for XC-type Ubiquiti devices on OpenWrt wiki at
   https://openwrt.org/toh/ubiquiti/common
