简介
本文显示如何执行在ISR (集成业务路由器)的访问接入节点镜像恢复与嵌入式AP802。 描述的方法此处取决于在事实AP802闪存分区从主机路由器是直接可访问的。 此技术不可能从路由器使用与嵌入式AP801;在这样平台上，您将需要执行从AP801控制台(启动装载程序的AP (接入点)镜像恢复。) (如何告诉是否有AP801或AP802)。

重新排版AP闪存
flash:1 ：文件系统是AP802使用的分区。 在我们的测验中，我们将格式化此文件系统消除它干净，然后重新启动AP802造成它启动到AP启动装载程序。(注意:请勿重新排版AP闪烁，除非必要-这用于说明目的执行此处。)

复制在路由器闪存上的AP IOS
复制从一个TFTP (简单文件传输协议)服务器的希望的AP IOS tarball在路由器的主闪存分区上。 在这种情况下，我们使用是自治IOS 15.2(4)JB5的ap802-k9w7-tar.152-4.JB5.tar。 (请参阅条款了解接入点IOS镜像。)

配置AP启动新建的IOS镜像
控制对AP802启动装载程序，并且配置它启动IOS镜像。 注意AP的IOS镜像通常呼叫flash: /platform featureset mx.version/platform featureset MX版本。 然后引导程序AP IOS。

整理路由器闪存并且为自治配置
现在请删除从路由器闪存的tarball，不再必要。 并且请寻址"WLAN_AP_SM-6-UNIFIED_IMAGE"消息，表明路由器认为AP应该运行轻量IOS，因此我们需要使用服务模块WLAN n bootimage命令告诉路由器AP是运行自治(或轻量)。

问：如何分辨ISR是否有AP801或AP802 ？
A1. 执行在AP的show version。
