Aruba 无线控制器常见故障解决 AC 650砖机复活记！

爱快北京无线

过去的10年内，Aruba 650 AC在很多中小企业以及连锁酒店大量应用，这些年不断的出现AC挂掉，反复重启的现象，近期解决了大量此类问题，现在给大家总结一下

1.其中有几例是POE供电造成主板烧毁，建议不要使用650上自带的POE去带135 2xx这种耗电量大的设备，最好是不要用650 POE带ap,如果实在要带，尽量越少越好

2.CPU背部变黄，虚焊，cpu直接烧毁，这种应该加强机房散热，检测主机风扇是否有停转现象，因为时间长了有些主机风扇都坏了，而使用人还不知道，继续使用，长期如此造成此现象，建议定期检查更换或者可以增加部分散热风扇原机风扇对新机来说还可以，但用了5年以上的老机器原机风扇有些力不从心

3.无法升级，反复重启，这些后期发现好多都是因为nand flash内垃圾太多，nand 坏块造成的，这个要及时清理垃圾用命令delete 和tar clean命令即可,nand 坏块这个问题不太容易解决，有很多机器因为nand坏块到关键部位造成tpm错误，这个问题暂时不太好解决，更换nand flash有可能解决，后期试验一下给提供结果.

4.无法升级固件，这种情况只能提前备份数据后，进入cpboot强行升级.
