show version多了条JUNOS Web Management [7.5R1.12]，呵呵，成功了。
还要配置如下：
test@Lab1> configure
Entering configuration mode
[edit]
test@Lab1#
test@Lab1# set system services web-management http port 80
test@Lab1# set system login user wanglinlin class super-user authentication plain-text-password
test@Lab1# commit
如果设备本来没有配置IP地址的，还需要配置IP地址
test@Lab1# set interface fxp0 unit 0 family inet address YY.YY.XX.XX/32
打开IE，就可以通过WEB方式配置、管理设备了。
附：
应急措施
以下是在升级不成功或需要中断升级的情况下可以采取的一些措施。
注意：最好的做法是只在紧急情况下使用这些措施。如果在升级过程中出现问题，请立即联系代理工程师或JUNIPER工程师。这些措施列在这里仅供在紧急情况下使用。
1.如果需要退回到原先的版本
如果因为新版本工作不正常或者是在升级过程中遇到其它问题，需要退回到原先的版本，则你可以重新安装自动保存在/var/sw/pkg 目录下的原先的版本。命令格式与升级操作是一样的，只是文件名不一样。
test@Lab1> request system software add /var/sw/pkg/jinstall-7.0R1.5-export-signed.tgz
test@Lab1> request system reboot
2.从FLASH启动失败
如果升级后系统无法从FLASH启动，则系统会自动从硬盘启动，硬盘上保存有原先的JUNOS版本和配置
我们需要RE启动时本地控制口的日志以确认RE启动失败的原因。
3.RE切换不正常
如果RE切换后主RE工作不正常，需要切回备份RE，可以在主RE本地控制口上执行以下命令：
test@Lab1> request chassis routing-engine master release no-confirm
