Downgrade the Base Stations
You can downgrade the base stations running Firmware version 5.0(1) only to the latest branch of Firmware
version 4.8(1) SR1.
Note
The firmware filename contains the version (v) and branch number (b). For example,
DBS-210_v0480_b0001.fwu is version 480 and branch 1. When you put the firmware version and branch
number into the
Firmware Update
page, you don't need the leading zeros.
During the downgrade, the base station LED flashes in the order green, red, green, and amber. Don't power
off the base station while the LED flashes. The downgrade may take about 30 minutes to 1 hour to complete
and reboot the base station.
