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

我们最近从 Cisco购买了一些新的AP3602E。

我试图理解为什么当我们向 AP 发送足够的功率时，这个 AP 不会打开无线电。我正在使用交换机的内联电源，但在 AP 启动后，它会发送%CDP_PD-2-POWER_LOW: All radios disabled到控制台。AP 上的 LED 呈绿色闪烁。

拓扑：

                       <------- cdp Req 13000mW

AP 正在运行 12.4(25e)JAL1arcvk9w8接收映像。

2960S 运行的是 12.2(55)SE7。

问题：我怎样才能让这个 AP 打开无线电？

我与 Cisco Wireless Consulting SE 交谈过...第一个问题是恢复映像（即rcv-w8映像）没有 Dot11 无线电的固件...所以我不得不上传新固件。

升级到ap32g2-k9w7-tar.152-4.JA1.tar（这w7是一个自治 AP 映像）后，Dot11radio 接口出现了。

纯粹提供信息......这是我们用于 2.4G 和 5.0G 调查的开放认证自治 AP 配置......

一些 3600 确实需要 802.3at 功率，看起来像这个，并且出于某种原因它只绘制 802.3af 功率级别。不确定交换机或 AP 代码中是否存在可能导致此问题的错误，但可以尝试以下几点。

在某些情况下（通常使用非 Cisco 设备），我不得不在界面上添加以下内容（在添加/删除之前关闭界面）：

power inline port 2x-mode

如果没有这样做，有时在接口上禁用 CDP 可以通过强制它使用 802.3at 的 IEEE 类协商而不是 CDP 来提供帮助。通常不那么节能，但可以解决问题。
