带有rcvk9w8图像的AP3602抛出“％CDP_PD-2-POWER_LOW：禁用所有无线电”

我们最近从思科购买了一些新的AP3602E。

我试图了解为什么当我们向AP发送足够的功率时，此AP无法打开无线电。我正在使用来自交换机的嵌入式电源，但是AP接通电源后，它将发送%CDP_PD-2-POWER_LOW: All radios disabled到控制台。AP上的LED闪烁绿色。

拓扑结构：

AP正在运行12.4（25e）JAL1a rcvk9w8接收图像。

2960S正在运行12.2（55）SE7。

问题：如何使此AP打开无线电？

问题：如何使此AP打开无线电？

我与Cisco Wireless Consulting SE进行了交谈...第一个问题是恢复映像（即rcv-w8映像）没有Dot11无线电的固件...因此我必须上载新的固件。

archive download-sw /force-reload /overwrite tftp://...当我处理较旧的Cisco AP 1242型号时，我通常使用升级映像。但是，在此图像下，直到使用debug capwap console cli... 我一直出现错误。

AP0006.6566.a57b#arch?

升级到ap32g2-k9w7-tar.152-4.JA1.tar（w7是自治AP映像）后，出现了Dot11radio接口。

纯粹是信息性的...这是我们用于2.4G和5.0G调查的开放式身份验证自主AP配置...

某些3600确实需要802.3at的功率，并且看起来就像这样，并且由于某种原因，它仅消耗802.3af的功率。不确定交换机或AP代码中是否存在可能导致此错误的错误，但是可以尝试以下两种方法。

在某些情况下（通常在非Cisco设备上），我不得不在接口上添加以下内容（在添加/删除之前关闭接口）：

power inline port 2x-mode

如果这样做不起作用，则有时可以通过强制接口使用802.3at的IEEE类协商而非CDP来禁用接口上的CDP。通常效率不高，但可以解决问题。
