简介
本文档介绍如何重置思科安全邮件网关(SEG)或安全网络设备(SWA)硬件设备（如果您使用启用身份验证方法）。
先决条件
使用的组件
- SEG AsyncOS 14.2.2或更高版本
- SWA AsyncOS 14.5.1-008或更高版本
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
问题
如果升级失败或服务损坏，则无法通过WebUI或网络访问SEG/SWA，这会将RMA作为唯一选项。SEG/SWA中的新功能允许将设备完全重置为出厂设置，这样就无需对设备进行RMA。
解决方案
SEG/SWA和管理员密码在手，通过控制台或以太网终端会话访问设备。
用户用户名：enablediag
password：管理员密码
可用命令包括新选项resetappliance
resetappliance选项会生成要选择的先前版本选项的列表。
选中后，设备会清除所有设置为系统默认设置，包括删除网络ip设置。
最终结果会生成一个完全未配置的SEG/SWA，准备进行设置。
完成resetappliance进程的输出示例。
