Download Firmware Ubiquiti EdgeMAX EdgeSwitch 1.8.3

Ubiquiti Networks has released version 1.8.3 of the firmware for the EdgeMax EdgeSwitches. The EdgeSwitches are characterized by extensive setting options, but require some network knowledge to get it running properly. Also, not all settings can be adjusted via the gui, so you have to start via the command line. The list of changes looks like this:

Important notes

Lite Version
We provide new favorite EdgeSwitch firmware with the Lite suffix. This firmware limits the maximum VLAN count from 4093 to 255, reducing the memory utilization compared to the normal firmware version. If you have no requirement for 255 and more VLANs, you might consider using the Lite firmware. Note that the Lite firmware reduces the total VLAN count to 255, not the allowed VLAN ID range. Please check your configuration before you update to the Lite firmware version, as VLAN config will be lost if there are more than 255 defined VLANs.

Memory re-tuning
This memory re-tuning mechanism checks the flag from firmware version 1.8.2 and after. The device will reboot again and perform memory re-tuning when the flag does not exist. That means that the system will reboot one more time if you are first launching this firmware on the unit. Memory re-tuning might takes about ~5-10 minutes on some units. If your EdgeSwitch does not respond after 10 minutes, please power cycle the unit manually.
