Installing 2T16S Network Processor Modules in the Cisco 4000 Series

78-3277-03

If the second 2T16S module in Figure 2 was replaced by an Ethernet module, the unit addresses would

be as listed in Table 3.

Accessing the Network Processor Modules

To access the network processor modules, you must remove the component tray.

Removing the Component Tray Procedure

Some Cisco 4000 series routers have a safety latch tab on the chassis that affects removing the

component tray. (See Figure 4 and Figure 5.)

If you have a chassis with a safety latch tab, follow the procedure in the next section “Removing the

Component Tray from a Chassis with a Safety Latch.”

If you have a chassis without a safety latch tab, follow the procedure in the section “Removing the

Component Tray from a Chassis without a Safety Latch.”

Removing the Component Tray from a Chassis with a Safety Latch

Warning

Hazardous voltages may exist in or near the power supply, so use extreme caution when working near

the power supply. Before starting any of these procedures, turn OFF power to the system, unplug the

power cord, disconnect any cables at the ports, and attach your ESD-preventive wrist strap.

Take the following steps to remove the component tray from a chassis with a safety latch:

Step 1 Turn OFF the system power.

Step 2 Attach your ESD-preventive wrist strap to your wrist and the other end to a grounded surface.

Step 3 Remove all network and power cables.

Step 4 Loosen the nonremovable chassis release screw on the rear panel of the chassis. (See Figure 4.)

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 until the safety latch catches. (See Figure 4.)
