Resetting
ODU
to factory defaults by power
cycling
Operators may reset a PTP 550 radio to default factory configuration by a sequence of power
cycling (removing and re-applying power to the device). This procedure allows operators to
perform a factory default reset without a tower climb or additional tools. The procedure is
depicted in Figure 53.
Procedure:
1
Remove the Ethernet cable from PoE jack of the power supply for at least 10 seconds.
2
Reconnect the Ethernet cable to re-supply power to the ODU for 3-5 seconds
and disconnect
cable to power off the ODU for
3-5 seconds
.

6
Reconnect the Ethernet cable to re-supply power to the
ODU
for at least 30 seconds and allow
it to go through the boot up procedure (Note: Device will go through an additional reset
automatically). This will reset the current configuration files to factory default configuration
(e.g. IP addresses, Device mode, RF configuration etc.). The device can be pinged from a PC to
check if boot up is complete (Successful ping replies indicates boot up is complete).

Access the
ODU
e using the default IP address of 192.168.0.1.
