Sun M5000Solaris 10系统的安装、打补丁及IPMP的配置目录一、安装准备 (3)节 1.01 1 M5000的初始设置 (4)节 1.02 2 添加用户及给机器加电 (4)二、安装系统 (15)三、打补丁 (49)四、做镜像 (86)五、配置IPMP (92)一、安装准备首先使用串口线将笔记本与M5000连接，端口的设置请看（图1-1）：图1-1操作系统安装以及IP地址配置如下：系统的分区如下：节 1.01 1 M5000的初始设置新出厂的机器，XSCF没有设置用户，需要使用串口进行初始用户的创建。

机器加插上电源后，XSCF启动完成后出现登陆提示符：根据提示，输入用户名default后，将前面板钥匙由锁定位置拧到维护位置，按回车，等待5秒后，将钥匙由维护位置拧到锁定位置，敲回车，这样系统就进入XSCF提示符了。

（钥匙顺序也可以相反，即开始本来在维护位置，那么就拧到锁定，再由锁定到维护）节 1.02 2 添加用户及给机器加电Change the panel mode switch to Service and press return...Leave it in that position for at least 5 seconds.

5.模拟信号和数字信号
模拟信号是指信号的因变量对时间的取值是连续变化的信号。
6.通信方式有几种？ 串行通信，并行通信 7.通信系统由哪几部分组成?各自具有什么功能?
通信系统是传递信息所需的一切技术设备的总和。它一般由信息源和信息接收者，发送、接收设备，传输媒介几部分组成。 信息源和接收者是信息的产生者和使用者 发送设备的基本功能是将信息源和传输媒介匹配起来， 即将信息源产生的消息信号经过编码， 并变换为便于传送的信号， 送往传输媒介。 传输介质指发送设备到接收设备之间信号传递所经媒介。它可以是无线的，也可以是有线的(包括光纤)。有线和无线均有多种传输媒 介，如电磁波、红外线为无线传输介质，各种电缆、光缆、双绞线等为有线传输介质。 接收设备的基本功能是完成发送设备的反变换， 即进行解调、 译码、 解密等。 它的任务是从带有干扰的信号中正确恢复出原始信息来， 对于多路复用信号，还包括解除多路复用，实现正确分路。
