解决ASR 5500系列“FanFailed”错误情况

简介

本文描述与风扇故障错误和解决方案涉及的问题报告由简单网络管理协议(SNMP)陷阱，看到在思科聚合服务路由器(ASR) 5500平台。这通常发生，虽然少见，在平台的正常操作。

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。

[local]ASR5500# show fan

Lower Rear Fan Tray:
  State:       Unknown
  Speed:       0%
  Temperature: Unknown

Upper Rear Fan Tray:
  State:       Normal
  Speed:       50%
  Temperature: 27C

Lower Front Fan Tray:

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：

3. 输入此命令为了验证风扇模块运行正确固件版本：

   [local]ASR5500# show hardware version fans 
   Thursday May 28 19:16:54 EDT 2015
   Fan Tray Controller Version 
   Upper Fan Tray: 0.2.5
   Lower Fan Tray: 0.2.5

4. 输入此命令为了验证清除了SNMP陷阱错误，并且没有错误，在风扇模块重新安装后：
