更新前的准备: 准备一根网线，一根 console 设备对应版本包，Ruijie TFTP Server 传输软件。 
步骤1：使用 console 线路配置交换机的接口地址，然后将笔记本电脑的任何（物理）网卡配置为相应的更新版本设备的同一网段地址，可以 ping 通。 注： 1.笔记本可以用网线连接交换机的任何物理接口(即所有接口都包含) Vlan 1.因此，交换机只配置 Vlan 1 地址即可) 2.路由器配置物理接口地址，连接相应端口。 3.本文设备为交换机。
Ruijie> enable ------>进入特权模式 Ruijie# configure terminal ------>进入全球配置模式 Ruijie(config)# interface vlan 1 ------>进入vlan 1接口 Ruijie(config-if)# ip address 192.168.1.1 255.255.255.0 ------>为vlan 1管理设置在接口上ip Ruijie(config-if)# exit ------>回到全球配置模式 ping 测试
Ruijie# ping 192.168.1.2 Sending 5, 100-byte ICMP Echoes to 192.168.1.2, timeout is 2 seconds: < press Ctrl C to break > !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms. 查看当前版本

步骤2：将 Ruijie TFTP Server 传输软件与设备对应版本包放在同一目录下。 步骤3：打开 TFTP Server 传输软件，选择文件所在目录，默认即可。
步骤4：使用 console 线将笔记本连接交换机 console 口，然后使用 CRT 软件登录交换机，并将软件包复制到设备中。 1.查看是否存在相同文件
# 该命令为显示设备中的文件
Ruijie# dir flash:
2.通过TFTP拷贝 RGOS.bin 文件至交换机flash:目录里
# 格式为 copy tftp://ip地址/软件包名 flash:软件包名
Ruijie#copy tftp://192.168.1.2/S29_RGOS11.4(1)B74P1_install.bin flash:S29_RGOS11.4(1)B74P1_install.bin
3.查看拷贝完成后 FLASH 里面内容
Ruijie# dir flash
