概括

PTP.650/670/700 units can be defaulted to factory setting using the power cycle recovery procedure. The document explains the recovery procedures and the conditions or situations for the radio recovery.

Cause

当有严重的配置错误时，丢失或忘记密码和未知的IP地址。恢复模式还允许加载新的主应用软件，即使现有主应用软件映像的完整性受到泄露。安装主应用软件的完整性问题最有可能的原因是在早期软件升级期间电源被中断的位置。

Solution

PTP 650/670/700恢复模式提供了一种从严重配置错误中恢复的方法，包括丢失或忘记密码和未知的IP地址。

ODU在以下情况下在恢复模式下运行：

  • 当主应用程序软件图像发生校验和错误时。
  • 当电源关闭电源时，将电源循环应用于ODU，电源关闭时段为5秒。

恢复模式支持一个IPv4接口,with IP address 169.254.1.1, and with default link settings. 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 in recovery mode (IPv4 only) are as follows:

  • 加载新的主应用软件。
  • 重置所有配置数据。此选项重置IP，以太网和安全配置
  • Reset IP and Ethernet configuration.
  • Reset (zeroize) critical security parameters.
  • Reboot with existing software and configuration.

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.

Entering recovery mode

使用此过程手动输入恢复模式。

Note
The unit may enter recovery mode automatically, in response to some failures. Once the unit has entered recovery, it will switch back to normal operation if no access has been made to the recovery web page within 30 seconds.

程序：

  1. Apply power to PSU for at least 10 seconds.

  2. Remove power for two seconds.

  3. Re-apply power to the PSU.

  4. When the unit is in recovery mode, access the web interface by entering the default IP address 169.254.1.1. The Recovery Image Warning page is displayed:
