Step 5

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.

Step 6 Set the component tray on your work surface.

Proceed to the later section “Removing Network Processor Modules.”

Removing Network Processor Modules

After you have removed the component tray from the chassis, you can remove the network processor

modules from the chassis.

Caution Some network processor modules are secured to the rear of the chassis with two external screws. On

modules with external rear mounting screws, including multimode FDDI modules, you must remove

these screws before the module can be safely lifted out of the chassis.

Take the following steps to remove a network processor module:

Step 1 Orient the component tray as shown in Figure 6, then remove the module mounting screw from the top

of the network processor module. Remove the two external rear mounting screws if the module has them.

Set all screws aside.
