8、引擎、线卡组成机箱：装载模块，为各个模块提供互联的接口电源：为路由器提供电力，分为直流电源和交流电源两种风扇：产生在机箱内流动的气流为系统提供散热功能引擎：系统的核心，引擎上有 MSFC、PFC、NMP、SFM 等芯片，同时操作系统和各种软件也安装在上面，为系统提供控制层面和转发层面线卡：用于连接其它网络设备的板卡。有多种型号，为系统提供各种类型速率的接口和多种类型的服务5.1 机箱7600 系列和 6500 系列交换机最常见的型号为 9 插槽型号。这是因为如果部署引擎冗余就需要占用 2 个插槽，这样 3、4、6 插槽型号支持的接口就会存在不足的情况影响交换机的扩展性，13 插槽型号 1-5
9、号插槽只支持单通道，因此性能没有提高，随着线卡的增多性能反而有下降。所以 9 插槽机型是部署的最多型号。5.1.1 7603Cisco 7603 Chassis Features Four RU (7-inch) compact chassis, up to 11 chassis per 7-foot rack Two interface slots plus two supervisor-mounted Gigabit Ethernet ports (gigabit interface converters GBICs) Network Equipment Building Systems
