问题描述
CE12800一般需要电源备份,如何确定电源模块、电源线的安装位置以及相关电源备份的配置?
告警信息
处理过程
CE12800电源的备份方式主要有三种:无备份、电源模块级别(Module)和电源源的级别(Source)。
  • 无备份,即任何电源模块故障即影响设备的正常运行,这种模式对电源模块的插接位置没有特殊要求,如果考虑后续有可能改造为电源源级别的备份,所有电源模块要求放置在左区或者右区(将电源区从中间均分,左右可以称为左区和右区)。软件不需要特殊配置,系统默认电源备份模式为电源模块级别。这里需要命令power redundant  non修改为无电源备份级别。不建议无备份方式。
  • 电源模块级别的备份以N+1为例,可以实现任一电源模块故障,而不影响设备的正常运行。这种模式对电源模块的插接位置没有特殊要求,如果考虑后续有可能改造为电源源级别的备份,所有电源模块要求放置在左区或者右区(将电源区从中间均分,左右可以称为左区和右区)。软件不需要特殊配置,系统默认电源备份模式为电源模块级别。
  • 电源源级别的备份以N+N为例,在两路电均正常工作情况下任一或者N个电源模块故障,或者可以实现任一路电源掉电,而不影响设备的正常运行。这种模式要求电源模块的插接位置有特殊要求,N个电源模块放置在左区,N个电源模块放置在右区(将电源区从中间均分,左右可以称为左区和右区)。软件需要特殊配置,系统默认电源备份模式为电源模块级别,这里需要命令power redundant  source修改为电源源的备份级别。

根因
建议与总结
软件的备份方式极容易忘记设置,将导致查看功率时可用功率增大,后续扩容后可能出现单路供电异常后设备供电不足导致部分单板无法加电,中断业务。
