1、2018/10/14,路由器日常维护胶片,Page 2,设备结构NE40E,1. 风扇塑胶面板 2. 风扇模块 3. 插板区 4. 进风框 5. 电源模块塑胶面板 6. 电源模块 7. 把手 8. 挂耳 9. 走线槽,Page 3,NE40E的单板槽位,Page 4,NE40E的单板外形SRU板外观部件图,SRU是NE40E的主控交换单元，负责系统的集中控制和管理以及数据交换。SRU采用1:1冗余备份设计。SRU板主要由系统主控单元、交换单元、系统时钟单元、交换同步时钟单元、系统维护单元组成。 SRU上有两块CF卡，一块位于SRU的PCB上，另一块在SRU的拉手条上。,Page 5,NE40E
2、的单板外形SFU板外观部件图,SFU是NE40E的交换处理单元，SFU之间采用无阻塞的交换网络架构来实现，其中交换网络采用华为研发的高速ASIC芯片，实现160Gbit/s流量的线速交换。,Page 6,NE40E的单板外形普通LPU外观部件图,LPU模块的主要功能有： 多种链路层协议（如Ethernet_II、PPP等）的处理和封装。 进行数据包流分类，用于监视用户流量；使用访问控制列表进行包过滤。 数据缓存管理和调度功能。 根据转发表进行数据转发。 识别控制协议报文，通过非线速处理接口转发到主CPU处理。,Page 7,NE40E的单板外形灵活插卡线路处理板外观部件图,Page 8,NE4
3、0E的接口编号原则,NE40E的接口编号使用“线路板槽位号/业务接口卡号/端口号”三维索引定位接口。以下就此三维索引的排列顺序和定义做出说明。 线路板槽位号 对于NE40E，槽位号从1开始计数，其计数范围是116。排列顺序为正对路由器前面板从左至右，从上到下递增（面板上有相应的标志）。 业务接口卡号 业务接口卡号从0开始计数，按照从左到右、从上到下递增。若单板没有业务接口卡，则该卡号为0。 端口号 端口号从0开始计数，按照从左到右、从上到下递增。 举例说明如下： 配置4号槽位10端口千兆以太网光接口板上的第3个端口，此接口命名为GigabitEthernet 4/0/2，相应进入接口视图的命令
4、为： Quidway interface gigabitethernet 4/0/2,Page 9,更换NE40E-8的防尘网,NE40E-8有两块防尘网：进风框防尘网、电源面板防尘网。 将手指伸入进风框面板两侧的抠手位，平行向外拉，将进风框面板取下，如图所示。 将进风框面板上的防尘网取下，如图所示。,Page 10,拆卸NE40E-8电源面板的防尘网,将手指伸入电源面板两侧的抠手位，平行向外拉，将电源面板取下，如图所示。 将电源面板上的防尘网取下，如图所示,NE40-8,NE40-8路由器,高度18U 中间两为SRU板（主控）槽位号为9、10 其它8块为业务接口板从左到右逻辑槽位号分别为1-
5、8 NE40-8有两块电源模块，不管插交流还直流模块，逻辑槽位号左为12、右为11，采用1+1热备份方式 机箱顶部有一个风扇，可热插拨，逻辑槽位号为13,Page 12,NE40-8机箱防尘网拆卸,先用双手拇指分别按下走线槽的两侧，在按下走线槽两侧的同时，双手将走线槽盖往外拉，此时槽盖会往下打开，然后将垂直嵌在走线槽盖中的机箱防尘网取出，如下图 如果不按下两侧，直接将走线槽往外拉，会损坏走线槽,Page 13,防尘网清洗指导,路由器采用的是海绵防尘网，海绵防尘网适合于干洗。 将网上较多的灰尘拍打掉。 用吸尘器将防尘网上面的灰尘吸净。,常用维护命令,利用display命令可以收集系统状态信息，根
