除了检查上面的项目，我们还复查并预排了一个系统演示，整个演示作为产品的最终展示服务于与客户进行外部的TRR。

例如，产品可以发送email通知、设置SNMP陷阱、执行一个控制动作比如重启一个服务、或者与另一个管理系统进行通信。

For example the product can issue email notifications, set SNMP traps, perform a control action such as restarting a server, or issue a communication to another management system.

但在此阶段，在继续安装产品之前，我建议您对管理系统(administrative)与管理(management)服务器进行备份。

At this stage, though, before proceeding any further with the product installation, I recommend you make backup copies of both the administrative and management servers.
