问题

有时FanFailed报警在ASR 5500平台被看到关于风扇第1和2如显示此处:

Tue Apr 01 16:07:07 2014 Internal trap notification 22 (FanFailed)
fan number 2 fan status Communication Error
Tue Apr 01 16:07:27 2014 Internal trap notification 22 (FanFailed)
fan number 1 fan status Communication Error

更低后方和更低前鼓风机当前报告UNKNOWN状态,并且节点卡的一般温度当时看来是好的。

解决方案

当您重新安装风扇模块时,此问题通常是解决的。完成这些步骤为了验证状态是正常:

  1. 滑风扇模块。等待两到三分钟然后滑它回到slot。
  2. 输入此命令为了验证风扇在正常状态:
