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
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

motherboards in the component tray. The motherboard was changed when the Cisco 4700-M was
introduced, and the new motherboard is also used in newer versions of the Cisco 4500-M.
Step 2
Caution
do not exert any side-to-side pressure because the handle might work loose and damage the network
processor module.
Figure 7 shows the network processor module and connector locations.

Support the component tray from underneath, either on your work surface or with your
Pull on the handle located on the upper right corner of the chassis to slide the component
tray out of the chassis shell while you support the component tray with one hand.
Set the component tray on your work surface.
Some network processor modules are attached to the rear of the chassis with two external
With the component tray in front of you (as shown in Figure 5 and Figure 6), remove the
module mounting screw from the network processor module, and the two external rear
mounting screws (not shown) if the module has them, and set the screws aside.
The Cisco 4500, Cisco 4700, and older versions of the Cisco 4500-M use very similar
To lift the module out of its connector after removing the module mounting screws, grasp
the network processor module handle and pull straight up. (See Figure 7.)
Do not rock the handle up and down when handling the network processor module, and
