Removing Network Processor Modules Figure 5-2 Component Tray Removal for Chassis Without a Safety Latch Chassis shell Chassis release screw H2899 Rear of chassis AUX CONSOLE Support the component tray with your hand INPUT 100-240VAC 50/60HZ 3.0-1.5 AMPS Handle Warning Support the component tray from underneath, either on your work surface or with your hands, to prevent it from falling. (See the hand in Figure 5-2.) Step 5 While facing the chassis rear panel, pull the handle on the right side of the router while supporting the component tray with one hand. Slide the component tray out of the chassis shell. Step 6 Set the component tray on your work surface. Removing Network Processor Modules If you are replacing shared memory single in-line memory modules (SIMMs), you must first remove the network processor modules. Follow the steps in this section to remove a network processor module. Caution Some network processor modules are mounted to the rear of the chassis with two external screws. On modules with external rear mounting screws, which include the Fiber Distributed Data Interface (FDDI) module, these screws must be removed before the module can be safely lifted out of the chassis, otherwise damage to the module will occur. Other types of modules may not have the two external rear mounting screws attached to the chassis. Step 1 With the component tray in front of you (as shown in Figure 5-3), remove the module mounting screw from the top end of the network processor module, and the two external rear mounting screws (not shown) if the module has them, and set the screws aside. 5-4 Cisco 4000 Series Hardware Installation and Maintenance
