Recovery Mode - Cambium Networks PTP 650 Series User Manual

Chapter 1: Product description

Recovery mode

The PTP 650 recovery mode provides a means to recover from serious configuration errors
including lost or forgotten passwords and unknown IP addresses.
Recovery mode also allows new main application software to be loaded even when the integrity of
the existing main application software image has been compromised. The most likely cause of an
integrity problem with the installed main application software is where the power supply has been
interrupted during an earlier software upgrade.
The ODU operates in recovery mode in the following circumstances:
•
When a checksum error occurs for the main application software image.
•
When a power on, power off, power on cycle is applied to the ODU with the power off period
being around 5sec.
Recovery mode supports a single IPv4 interface, with IP address 169.254.1.1. Recovery mode does
not support IPv6.
Note
When Recovery has been entered through a power on/off/on cycle, the ODU will revert
to normal operation if no web access has been made to the unit within 30 seconds.
This prevents the unit remaining inadvertently in recovery following a power outage.
Recovery mode options
Options in recovery mode (IPv4 only) are as follows:
• Load new main application software.
•
Reset all configuration data. This option resets IP and Ethernet configuration, and erases
(zeroizes) critical security parameters.
•
Reset IP and Ethernet configuration.
•
Erase (zeroize) critical security parameters.
•
Reboot with existing software and configuration.
Note
If recovery mode has been entered because of a checksum error, after a 30 second
wait the ODU will attempt to reboot with existing software and configuration.
The recovery software image is installed during manufacture of the ODU and cannot be upgraded
by operators.
