客户反映：SUN T5220后面板告警，及前面板FAN指示灯告警。
1/登进串口控制台，默认进入“sc>”用户终端(此终端为admin用户所登陆,之前有人登陆。)
注：登进串口控制台，root用户（初始密码：changeme）,在无admin用户情况下，创建admin用户:
create /SP/users/admin
password:admin
-->set /SP/users/admin role=Administrator
-->set /SP/users/admin cli_mode=alom
创建完后，注销
-->exit
2/既然在“sc>”提示符下，则先“help”
sc> help
