精选优质文档-倾情为你奉上中国移动通信集团山西有限公司7750SR设备常见故障处理指导书 上海贝尔阿尔卡特股份有限公司 工程服务部 二零零七年十月 1 检查硬件运行状态1.1 7750 SR硬件介绍7750 SR由机箱、SF/CPM、IOM、MDA构成。7750 SR分为SR-12、SR-7、SR-1 3种型号。SR-12 共有12个插槽，其中2个插槽为主控板（SF/CPM）插槽，10个插槽为业务板插槽，最多可插10个IOM、20个MDA。SR-7共有7个插槽，其中2个插槽为主控板（SF/CPM）插槽，5个插槽为业务板插槽，最多可插5个IOM，10个MDA。SR-1主控板固化在机箱内，不需要外配主控板和IOM，最多提供2个MDA插槽。7750 SR-12的IOM 槽位从左起至右编号为1至10槽，板卡为垂直方向定位。每个IOM上目前最多可以安装2个MDA，MDA的编号为上槽slot 1，下槽slot 2。 7750 SR-12最多可以安装2块SF/CPM，位于中间2槽，这2个槽位被分别命名为slots A 和B。至少1个SF/CPM 必须安装，冗余的SF/CPM工作在 stanby状态，一旦主用SF/CPM出现故障，冗余SF/CPM将自动接管系统控制。7750 SR-12在面板前部安装滤风器、SF/CPM、 IOM,、和MDA，电源和风扇在后部安装。 见图1和图2。图1: 7750 SR-12前面板图1Cable management system 2Chassis slot numbers 3MDA (installed) 4Full slot panel blank 5SF/CPM 6MDA blank panel 7Rack mounting brackets 8Air vent 9ESD plug 10Compact flash slots 11Compact flash slot 3 (cf3:)表1： 机箱前面板功能表 图2: 7750 SR-12 后面板图1Grounding studs2Rack mounting brackets 3Impeller (fan) trays4VDC studs for DC power cable5RTN studs for DC power cable6Safety cover 7OFF/ON DC switch8Impeller (fan) tray faceplate9DC PEMs. The top slot is referred to as PEM Slot 1.
