I can not ping or manage my OFDM backhaul, forgot

I can not ping or manage my high speed (OFDM) backhaul, 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.
