I can't ping or manage my 5.4GHz or 5.7GHz 30/60 or 150/300 Mb OFDM BH, forgot the IP address, and forgot the password

Solution for OFDM high speed backhaul only: Reset factory IP (Master 169.254.1.2) (Slave 169.254.1.1) by powering up radio, then press and hold reset button on the Power IDU for 20 seconds. This will reset the IP and password (no password) and default to Slave.
